Best Reviewed Flicker Free 27" 1440p AHVA/IPS/PLS

Always purchase from retailers with hassle free return and exchange policies.  Read retailers return and exchange policies before buying.

My recommendations are based off of testing more than 60 monitors and reading in-depth reviews from over fifteen reviewers across the realm.

Many monitors not found in this thread likely perform well, but it makes more sense to buy well reviewed monitors, and I like having sources to refer to, even though I do not always agree with them.

If a monitor is not mentioned it is because it has not been reviewed properly, been reviewed at all or is mediocre.  All monitors suffer from regular quality control issues: back-light bleeding and pixel issues (dead and stuck pixels).

Recommendations are PWM or Flicker Free:

I do not recommend monitors which use low LED PWM Dimming frequencies since they ruin motion clarity and cause some people to suffer from health issues like head aches and eyestrain.  LED PWM Dimming Side Effects.

Best 60-75hz Monitors

Glossy* Monitors

*There are four kinds of glossy coatings used on monitors, they are the almost-glossy or low haze coating, full glossy, semi-glossy coating and plasma deposition coating.

There's only three modern (2016-2019) glossy-type coated 1440p monitor, the Dell S2718D, Nixeus Pro VUE27S and Planar PXL2790MW.  Neither the Dell nor Nixeus are as accurate as the best matte competitors, and the Dell uses a semi-glossy coating which looks washed out under bright lighting, and looks grainy when viewed slightly off angle.

The Nixeus PRO VUE27S and Planar PXL2790MW use coated tempered glass some call Plasma Deposition Coating which is the clearest and most vibrant coating, but has a glass covered black bezel which vastly reduces the perceived black depth.  The perceived black depth can be increased with bias lighting (light placed behind the display) or by placing non-stick silver tape tape on the black bezel.

The Planar is very accurate while the less accurate Nixeus needs to be set to the User mode to reduce the strong preset blue tint, and has high input lag (around 27ms if measured with the Leo Bodnar device) for a modern (2019) 1440p monitor.  I tested the Planar and measured a 20ms delay with the Leo Bodnar device while Tom's Hardware, using their own testing methodology, measured 88ms for the Nixeus and 81ms for the Planar, which is a 7ms difference, hence my 27ms estimation for the Nixeus.

PDC coated monitors are the clearest, least reflective and most vibrant type of glossy monitors, but the black looks greyish due to the perceived black depth decreasing glass covered black bezel.  The perceived black depth can be increased with bias lighting (light placed behind the display) or by placing non-stick silver tape tape on the black bezel.


Matte Monitors

1.) Samsung S27H850QFU (adjustable stand, AMD Free-Sync & 75hz)
2.) Asus VZ27AQ (AMD Free-Sync & 75hz)
3.) Dell S2719DM (AMD Free-Sync & 75hz)
4.) Acer BE270U (AMD Free-Sync & 75hz)

April 3rd 2020 Update thanks to stplsd

The S27H850QFU uses low frequency LED PWM Dimming (source) when the brightness is set below a certain point (x/100).  It probably uses low frequency PWM when the brightness is set under 36 (0-35/100) like its predecessor the S27H850QFI.

The Asus VZ27AQ (Free-Sync & 75hz), Dell S2719DM (Free-Sync & 75hz), Dell U2719D (very accurate PLS), Dell U2719DC (IPS with USB-C), iiyama XUB2792QSU-B1 and Samsung S27H850QFU (best/most accurate; Free-Sync & 75hz) are the best of the non-wide gamut 2560x1440 IPS/PLS 60-75hz monitors for casual (non 144hz+) gaming and preset color accuracy wise.

*The Dell S2719DM (74hz) and iiyama XUB2792QSU-B1 (73hz) drop or skip frames when overclocked above the bracketed refresh rates when connected to Nvidia graphics cards pre-Nvidia Free-Sync supporting drivers.  I'm not sure about the others or if the new Nvidia drivers from January 14th 2019 and on fix this issue since these monitors were tested before then.

The S2719D has fake HDR (lacks wide gamut 8 bit panel with full DCI-P3 color space coverage, local dimming and high brightness), only two HDMI, and the matte coating is slightly grainier than some competitors according to PC Monitors.

The Asus PA27AC and Viewsonic VP2768 only supports 60hz and lack Free-Sync, but are extremely accurate and supports hardware calibration with an accurate colorimeter like the X-Rite i1 Display Pro, and have 14 bit 3D Look Up Tables which help reduce banding and color and shade differentiation.

The very accurate and delay free BenQ PD2710QC, Dell P2720DC (USB-C), Dell U2719D, Dell U2719DC (USB-C), LG 27QD58P-B and Philips 272B7QUPBEB (USB-C) are also great 60hz matte 1440p options with 1000:1+ contrast and height adjustable stands.

Some other competitors are the Acer RC271U, Acer BE270U (Free-Sync & 75hz), AOC Q2790PQU, Dell U2715H, Dell U2717D, S2718D (semi-glossy), Lenovo L27q-10 IPS DP, Philips 272B8QJEB, Viewsonic VX2778 which aren't as accurate and/or have lower contrast than the monitors mentioned above.

5.) Razer Raptor 27 (20-144hz AMD Free-Sync) IPS type
5.) Gigabyte AORUS AD27QD (48-144hz AMD Free-Sync) Innolux IPS
6.) Asus MG279Q (30-90hz AMD Free-Sync) AHVA
6.) Nixeus NX-EDG27Sv2 & NX-EDG27v2 (30-144hz AMD Free-Sync) AHVA
7) Acer Nitro VG270UP (40-144hz AMD Free-Sync & 120hz back-light strobing = Visual Boost Response); Innolux IPS version
8.). Acer VG271 (40-144hz AMD Free-Sync & 120hz back-light strobing = Visual Boost Response); Innolux IPS


The Acer Nitro VG270UP (AUO AHVA panel) and Eizo Foris FS2735 is the best 144hz 1440p AHVA panel since they are very accurate as well as supports back-light strobing; the Acer is significantly cheaper, but lacks a height adjustable stand and USB ports, and Acer replaced it with an inferior Innolux IPS panel which is less accurate and has slower pixel response times. 

The Acer XF270HUA uses an AHVA panel with faster pixel response times (less ghosting) than the Innolux IPS panels, as well as is very accurate.  The  Acer Nitro XV272UP and Gigabyte AORUS AD27QD are very similar, but the Acer is more accurate out of the box and when set to the over-saturation reducing sRGB mode.

The 27GL850 is also excellent, but needs to be set to the sRGB mode (which is very accurate and has adjustable brightness but locked color controls) to prevent the wide gamut panel from over-saturating the color of non-HDR content.  The 27GL850 has negligible or very low input lag and very fast pixel response times with minimal overshoot, but the overdrive needs to be set from Normal to Fast at 144hz to provide the fastest pixel response times, and to Normal at 60hz to prevent obvious overshoot ghosting.

The Pixio PX7 Prime and ViewSonic VX2758-2KP-MHD have negligible input lag, superior gamma tracking and sRGB (99.5% measured by Rtings) color space coverage than the LG 27GL83A-B which has faster pixel response times (less ghosting) and less color bleed (in gradient tests) than both the Pixio and ViewSonic.  The Pixio PX7 Prime comes with a height adjustable stand, 165hz support and more inputs than the Viewsonic, but the ViewSonic  VX2758-2KP-MHD has better black uniformity (based on Rtings reviews) and slightly faster pixel response times (less ghosting).

The Gigabyte AORUS AD27QD (Innolux IPS) is the most consistently accurate 144-165hz 1440p AHVA/IPS panel with Free-Sync along with the Eizo FS2735, has a semi-wide gamut Innolux IPS panel with some HDR support and great gaming performance, but it is slower than the AHVA panels and LG IPS panel in the LG 27GL850.  Read my in depth Gigabyte analysis here for much more information about how the reviewed units compare.

The 170hz ASUS ROG Strix XG279Q is faster than the Gigabyte monitors, BenQ EX2708Q and a few others, but also over-saturates SDR color (HDTV/REC 709 & sRGB) by over 30% and does not have a good SDR color mode.

The BenQ EX2780Q is very accurate when set to the Standard and Rec 709 Picture modes; the Standard mode uses the native wide gamut which covers 94% of the DCI-P3/HDR color space and over-saturates SDR color (HDTV/REC 709 & sRGB) by 33% while the REC 709 mode accurately emulates the REC 709 color space without significant over or under-saturation and should be used when not viewing HDR content.  The BenQ has negligible input lag (<4ms measured with the SMT Tool) and fast pixel response times when the preset AMA High Response Time setting is used, but it's not as fast as IPS competitors like the LG 27GL850 which Playwares measured a 3ms pixel response average time compared to the BenQ's 6-7ms average.

The Razer Raptor 27 is very accurate, but has a slight preset red tint and over-saturates the color of non DCI-P3 content (HDTV/REC 709 & sRGB) by 36% since it uses a wide gamut and HDR capable panel without a properly functioning sRGB emulation mode.  The HDR mode is more accurate than the SDR modes, and the Razer has negligible input lag and fast pixel response times for a non-TN panel.

Do to a lack of reviews I can't determine if the BenQ is faster than the Razer or vice versa, but I do know that the BenQ has a properly functioning SDR (HDTV/REC 709 &

The Samsung C27HG70 uses a VA panel with both back-light strobing, Free-sync and decent HDR support for the price.  It has much better image quality than the TN panels, but slightly less sharp text caused by the curved VA panels pixel structure, and slower pixel response times which causes more ghosting, or smearing of black, browns and greys, especially medium and dark variants of these colors and shades.

The Asus MG279Q has a limited Free-Sync range, but is fairly accurate, has faster pixel response times than the Innolux IPS version of the VG270UP and Nixeus, and has a perceived black depth increasing matte grey bezel.  The Free-Sync range can be increased to 60-144hz with the Custom Resolution Utility made by ToastyX.

The non-S version, the NX-EDG27v2 does not come with a height adjustable stand.  The Nixues is very accurate, but is a bit too warm (5800k color temperature) or has a minor preset orange or red dominance.  It can be considered to be display free or to have negligible input lag (TFT Central measured <5ms with the SMT Tool), but has significantly slower pixel response times than some AHVA panel using competitors, however, it is important to remember that the Nixeus is one of the cheapest 144hz 1440p non-TN panels, and that the Innolux IPS panels are also slower than the best AHVA panels such as the Acer XF270HUA bmiidprzx.

I'm not sure if the Nixeus is slower than the IPS version of the VG270UP since they were tested by different reviewers, and the Nixeus as better preset gamma accuracy than the VG270UP, but it can be improved by selecting the sRGB mode which locks the brightness and color controls.  Both are two of the cheapest 144hz 1440p non-TN panels, so until more reviews come they will be equally ranked.

Best 144hz 1440p Monitors with G-Sync

1.) Viewsonic XG2703-GS (30-144hz Nvidia G-Sync) AHVA*
2.) AOC AG271QG (30-144hz Nvidia G-Sync) AHVA*
3.) Asus PG279QE or QZ (60-165hz Nvidia G-Sync) AHVA
3.5) Asus PG279Q (30-144hz Nvidia G-Sync) AHVA*
4.) ViewSonic XG270QG 30-144hz Nvidia G-Sync) IPS*
5.) Acer XB271HU (30-165hz Nvidia G-Sync) AHVA*


*Support 165hz overclock

There are five 144-165hz 2560x1440 matte AUO AHVA panels (marketed as IPS) with Nvidia G-Sync, of which the AOC AG271QG is currently the best since the Viewsonic XG2703-GS was discontinued.  The other two options are the Acer XB271HU (least accurate), and Asus PG279Q (overpriced and worst build quality) and PG279QZ, but none have gamma settings to combat potentially low preset gamma, the Acer suffers from a bit of overshoot ghosting at 60hz (important for console gaming), and the Asus can not scale 1080p very well.  All of these monitors suffer from an obvious preset green/yellow tint, as well as tend to under-saturate blue.  The Acer is the least accurate of the bunch, and AOC tends to purposefully preset their monitors gamma too low, but at least AOC has multiple useful gamma settings to achieve more linear 2.2 gamma while the Acer and Asus's gamma can only be lowered resulting in more washed out colors.

The XG270QG is very accurate aside from a slight warm preset green tint, and can fully cover the SDR (HDTV/REC 709 & sRGB) color spaces, but has average contrast (850:1) and over-saturates the color of non DCI-P3 content (HDTV/REC 709 & sRGB) since it uses a wide gamut and HDR capable panel without a properly functioning sRGB emulation mode.  The ViewSonic XG270QG has negligible input lag and fast pixel response times for a non-TN panel at all refresh rates with the response time is set to the Standard (no overshoot) and Advanced (faster but with minor overshoot) settings.

Acer H277U

Review by Les Numeriques

The Acer H277HU uses a 60hz matte 8 bit 2560x1440 frame-less LG AH-IPS panel with good preset color accuracy, lots of inputs, fast pixel response times with minimal overshoot ghosting, but is not VESA compliant, and its frame-less casing has an inner black bezel which ruins its perceived black depth.

Review by Trusted Reviews

Accurate matte 2560x1440 144hz AUO AHVA (marketed as IPS) panel with AMD Free-Sync (40-144hz range supported by the Displayport and HDMI 2.0) with a fully adjustable stand, Displayport, Dul-Link DVI, HDMI 1.4, HDMI 2.0 (144hz), 4x USB 3.0 and 3.5mm Audio In and Out.


Acer XB271HU

Review by Alexander Gryzhin (=DEAD=)
Measurements and Review by Belgium Hardware
Review by NCX (archived version)
Review by PC Mag
Review by Rtings
Review by Trusted Reviews

It's pretty much the same as the PG279Q.  The Acer XB271HU uses a 27" 2560x1440 resolution 8 Bit AUO AHVA panel, a nearly grain free matte coating, has good color presets aside from a preset green tint, a frame-less casing with an inner black bezel which decreases the perceived black depth, fast pixel response times and a 144hz refresh rate.  G-Sync (Nvivida GPU required) works from 30-165hz (144hz is the default maximum refresh rate but it can be overclocked to 165hz), eliminates tearing and lag, but Lightboost is limited to 120z.  It also has an HDMI input which allows it to work with external devices like consoles.


Acer BE270UA

Review by PC Mag
Review by PRAD (slightly too high gamma)
Review by Toms Hardware (high 2.4+ gamma)

The BE270HUA has a fully adjustable stand, a fake frame-less casing with a perceived black depth decreasing inner black bezel, a native 75hz refresh rate, and supports AMD Free-Sync.  It's not very accurate since it can come with high preset gamma and a strong preset yellow tint.

Acer Nitro VG270UP

VG270UP AHVA Panel Review by =DEAD=
VG270UP Innolux IPS Panel Review by =DEAD=
Review by Les Numeriques (unsure if AUO AHVA or Innolux IPS panel)

The Acer uses a fake bezel/frame-less (it has an inner black bezel which reduces the perceived black depth versus a grey bezel) 144hz AUO M270DAN02 AHVA panel (advertised as IPS) with Displayport (Free-Sync + 40-144hz range), HDMI 1.4, HDMI 2.0 (Free-Sync + 40-144hz range) and 3.5mm Audio Out.  It supports AMD Free-Sync (40-144hz range), 120hz back-light strobing (named VRB=Visual Boost Response,

The reviews by =DEAD= review contains photos of the Test UFO Ghosting test which proves that the AUO AHVA panel is faster (OD Normal) out of the box, has a useful Extreme overdrive setting with only a bit of overshoot ghosting, which is noted in this section of the review.

Test UFO Ghosting Test Overdrive Comparisons: AUO AHVA versus Innolux IPS

The AUO AHVA panel has significantly more accurate preset color accuracy, especially the gamma since  the Innolux IPS has low gamma (scroll down to see this chart) while the AUO AHVA panel has nearly perfect 2.2 preset gamma and 93% DCI-P3 color space coverage for games with HDR support. The Innolux panel does use a semi-wide gamut panel which over-saturates the colors of SDR (HDTV/REC 709 & sRGB) content out of the box, but does have an sRGB mode to prevent the 34% over-saturation, as well as offer proper 2.2-ish gamma; AHVA vs IPS sRGB Color Space comparisons.

The last significant difference is the AUO AHVA panel suffers from white glow when viewing black while the Innolux IPS suffers from brownish-red glow; compare multiple photos: AUO AHVA vs Innolux IPS.

Conclusion:

The AUO AHVA panel is better since it has superior preset color accuracy or image quality for the majority of consumer content which use SDR color spaces (HDTV/REC 709 & sRGB), and has faster pixel response times and less overshoot ghosting than the Innolux panel. The Gigabyte AORUS AD27QD has similar overdrive, but is significantly more accurate than the Innolux VG270UP, and has a height adjustable stand which makes it worth the extra money since height adjustable stands cost at least 50$ US, and the 150$ US X-rite Colormunki is the cheapest accurate colorimeter.


Acer Nitro XV272UPBMIIPRZX

Review by =DEAD=
Review by PRAD (minor 720p scaling issue)

Fully adjustable matte 144hz 2560x1440 10 bit (8 bit +FRC) Innolux IPS panel with AMD Free-Sync (48-144hz), Disaplayport (144hz), HDMI 1.4 (70hz), HDMI 2.0 (144hz), 4x USB 3.0 and 3.5mm Audio Out.  The Innolux IPS panel is wide gamut and supports 95% of the DCI-P3 (HDR) color space natively, so the monitor must be set to the sRGB mode to prevent the over-saturation of SDR media (HDTV/REC 709 and sRGB) color.  The XV272 is very accurate out of the box, as well as when set to the sRGB mode which should be used to prevent color over-saturation when not viewing HDR content.  The HDR modes limited dynamic range causes severe black crush or the loss of detail in dark content in games like Resident Evil 7 tested by PRAD.  The XV272UPBMIIPRZX has the same overdrive as the Innolux IPS panel in the VG270UP which means that it is slower than the 144-165hz 1440p AUO AHVA panels.


Acer VG271UP

Added the Review by Rtings to my Best Reviewed Flicker Free 144-165hz 1440p Monitors and Best Reviewed Flicker Free 27" 1440p AHVA/IPS/PLS buying guides.

Matte 144hz 2560x1440 10 bit (8 bit +FRC; 10 bit color only supported at 120hz) Innolux IPS panel with AMD Free-Sync (48-144hz), Disaplayport (144hz), 2x HDMI 2.0 (144hz), 4x USB 3.0 and 3.5mm Audio Out.  The Innolux IPS panel can decode HDR, but lacks all features a panel needs to truly display HDR content such as a true wide gamut panel.  The VG271UP is fairly accurate, but not as accurate as the wide gamut panel in the Acer XV272.  The VG271UP has negligible input lag and fast pixel response times without overshoot ghosting, but the Innolux IPS panel in the VG/XV Acer's and Gigabyte AD27QD are not as fast as the 144hz 1440p AHVA panels in competitors like the Acer XF270HU.

AOC AGON AG271QG

Review by Alexander Gryzhin (=DEAD=)
Review by Digital Versus
Review by PC Monitors
Review by Playwares
Review by PRAD (low preset gamma)
Review by Sweclockers

The AOC AGON AG271QG uses a 27" 2560x1440 essentially grain free matte AUO AHVA panel with 30-165hz Nvidia G-Sync range.  It has a fully adjustable stand, lots of inputs and a matte black bezel.  The AG271QG is the best of the AHVA panels (marketed as IPS) since it has better resolution scaling (vs Asus; important for console use and 1080p) and two different gamma settings to combat the potentially low preset gamma all 144hz 1440p G-Sync AHVA (marketed as IPS) panels can come with, as well as has 2 useful overdrive settings and better build quality than the Asus which has a fake-thin casing with a perceived black depth reducing inner black bezel.  The AOC AG271QC reviewed by PRAD came with low preset gamma while the rest of the tested units are great.

Matte LH AH-IPS with Displayport, 2x HDMI, VGA and 3.5mm Audio Out.

AOC Q2790PQU

Review by Belgium Hardware & Measurements

Fairly accurate, fully adjust-able and delay free matte LG AH-IPS with Displayport, 2x HDMI 1.4, 4x USB 3.0, VGA and 3.5mm Audio In & Out.  The sRGB mode is fairly accurate while the preset Standard mode is too blue and green, and the User mode which unlocks the color controls suffers from more of a preset blue and green dominance, and both the Standard and User mode have too high preset gamma averaging between 2.3 and 2.4.  Tom's Hardware measured a 63ms delay with their own methodology which translates to over 20ms if measured with the Leo Bodnar device which means it has high input lag for a 1440p monitor made after 2016.


AOC Q27P1

Review by Playwares

Matte 27" 1440p IPS with a fully adjustable stand, perceived black depth increasing dark matte grey bezel, Displayport, Dual-Link DVI, HDMI, VGA, 4x USB 3.1, and 3.5mm  Audio In & Out.  The AOC has very low preset gamma (<1.75=very washed out colors and shades), but can be improved by setting the Gamma to 3, suffers from a strong preset green tint and can't, but almost covers the HDTV/REC 709 or sRGB color space, and slightly under and over-saturates colors.

The Asus MG279Q uses a 27" 2560x1440 resolution 8 Bit AUO AHVA panel, a nearly grain free matte coating, has excellent colour presets when the Racing mode is selected, a high quality matte grey bezel which vastly increases the perceived black depth, fast pixel response times and a 144hz refresh rate.  Free-Sync (AMD GPU required) works from 30-90fps, eliminates tearing and lag, but the has >10ms delay when not set to 144hz.

Asus PG279Q

The Asus PG279Q uses a 27" 2560x1440 resolution 8 Bit AUO AHVA panel, a nearly grain free matte coating, has good colour presets aside from a preset green tint, a matte black bezel and an inner black bezel which decreases the perceived black depth, fast pixel response times and a 144hz refresh rate.  G-Sync (Nvivida GPU required) works from 30-165hz (144hz is the default maximum refresh rate but it can be overclocked to 165hz), eliminates tearing and lag, but Lightboost is limited to 120z.  It also has an HDMI input which allows it to work with external devices like consoles.

Asus PA27AC

Review by Alexander Gryzhin (=DEAD=)
Review by IBXT

Matte fake frame-less 8 bit +FRC (unsure if AHVA/IPS/PLS despite marketing as IPS) panel with accurate color presets, AMD Free-Sync, 75hz and hardware calibration (requires colorimeter like the X-Rite i1 display pro) and 14 bit 3D LUT.  The hardware calibration feature can not provide as accurate results as free calibration software such as dispcalgui.  Reduce the Trace Free setting from 60 to 40 to reduce the obvious overshoot ghosting, and 20 to get rid of the overshoot entirely.


Asus PG279QZ

Review by Rtings

The Asus PG279QZ is an updated version of the PG279Q (2015), released in 2019, and with zero improvements.  The PG279QZ is fully adjustable, has Displayport (30-165hz Nvidia G-Sync), HDMI, G-Sync (Nvidia GPU required), ULMB (120hz back-light strobing), 2x USB 3.0 and the same fake-thin matte grey casing with an inner black bezel which decreases the perceived black depth.  The PG279QZ Rtings tested has excellent all-around performance, however, without more reviews available, it's impossible to know if it is consistently accurate unlike the PG279Q.

The VG27AQ is a fully adjust-able, matte, 144hz (over-clocks to 165hz over Displayport), 2560x1440 AUO AHVA panel with AMD Free-Sync (48-165hz range), back-light strobing (ELMB) Displayport (over-clock-able to 165hz), 2x HDMI 2.0 and 3.5mm Audio Out.  The VG27AQ has very accurate preset color accuracy (Racing Mode), and has very low or negligible input lag.  The VG27AQ needs to have the overdrive (Trace Free) reduced from 60 to 0 to get rid of excessive overshoot ghosting at 60hz and has slow pixel response times at 60hz, but performs well at 144, 155 and 165hz when the over drive (Trace Free) setting is kept to the default 60 setting.  TFT Central provides Trace Free 80 measurements which prove that the VG27AQ suffers from over 20ms of overshoot ghosting during many transitions which I find unacceptable which is why I recommend using Trace Free 60.


Asus PG279QE

Review by =DEAD=

Fully adjustable, matte, 2560x1440, 165hz AUO AHVA panel with 30-165hz Nvidia G-Sync, Displayporty, HDMI 1.4 (no G-Sync nation), ULMB (120hz back-light strobing) and 2x USB 3.0.  The Asus PG279QE is an updated version of the PG279Q (2015), released in 2019, and an alternative to the PG279QZ which is also an updated version of the PG279Q with zero improvements and slightly different casing and stand material.  The PG279QE is very accurate, delay free and has excellent overdrive with minimal to no overshoot.


ASUS ROG Strix XG279Q

Review by PRAD

Fully adjust-able, matte, semi-wide gamut, 170hz, 2560x1440 IPS (probably AHVA) panel with AMD Free-Sync, ELMB (back-light strobing), Displayport, 2x HDMI 2.0, 2x USB 3.0 and 3.5mm Audio Out.  The XG279Q has 1100:1 contrast, and is quite accurate DCI-P3 color space coverage (91%; it over-saturates SDR color by over 25% and does not have a good sRGB mode) and colors aside from a minor blue tint (6900k measured color temperature) and slightly too low and downward-sloping gamma which averages around 2.09.  The XG279Q has negligible input lag, great 60hz and 144-170hz overdrive with fast pixel response times and minimal overshoot when the Overdrive 3 setting is used.

The BenQ PV270 is a wide gamut monitor created for those who calibrated their monitors use programs which support color management.  It has a 14 bit 3d LUT, color compensation, better color presets and overdrive (less overshoot ghosting) than the SW2700T, and BenQ's hardware calibration program, Palette Master works better with the PV270.

The BenQ SW270C is a matte, fully adjustable 2560x1440 wide gamut IPS* panel with AQCOLOR, CalMAN Pantone hardware calibration, Displayport, 1x HDMI 1.4a, 1x HDMI 2.0, a monitor hood, an SD Card Reader, USB-C, 2x USB 3.0 and a 16 bit 3D Look Up Table.  The Adobe RGB, DCI-P3, M-Book and sRGB modes are all very accurate, and the sRGB mode provides from emulation with significant over and under-saturation, but the SW270C suffers from gradient banding both before and after calibration which is a shame since it has a 16 bit 3D Look Up Table.  The SW270C has fast pixel response times for a 60hz AHVA/IPS/PLS panel, and is free from obvious overshoot ghosting (AMA On), but has a 20ms  (measured by Playwares with the SMT Tool 2.0) or 31ms (measured by PRAD with an oscilloscope) delay or input lag.

Matte 144hz, 2560x1440, wide gamut (DCI-P3/HDR coverage) IPS panel (unsure if AHVA or IPS) with AMD Free-Sync, Displayport, 2x HDMI 2.0, a remote control, USB-C and 3.5mm Audio Out.  The BenQ is preset to the M-Book mode which has very high, black crush inducing 2.6+ gamma and is not very accurate, but can be improved by switching to the vthe Standard Picture Mode which uses the native wide gamut which over-saturates SDR color (HDTV/REC 709 & sRGB) by 33%.   The REC 709 mode locks the color controls, has high, slight black crush inducing 2.4 gamma and is limited to 93.6% sRGB color space coverage which combined with the locked color controls, is below average.  The BenQ has negligible input lag (<4ms measured with the SMT Tool) and fast pixel response times when the preset AMA High Response Time setting is used, but it's not as fast as IPS competitors like the LG 27GL850 which Playwares measured a 3ms pixel response average time compared to the BenQ's 6-7ms average.

Dell U2715H

Review by Daywalker
PRAD's Review
TFT Centrals Review

The Dell U2715H has good color presets, fast pixel response times, minimal overshoot and a low delay like the Asus PB278QR and LG 27MB85R-B.  The U2715H is overpriced uses LG's frame-less casing which is not actually frame-less.  Frame-less monitors have inner black bezels which ruin the perceived black depth and make dark content look a bit washed out, just like glossy black and matte black bezels do.  Example: notice how light the black letter box bars look compared to the monitors inner black bezel.

Review by Rtings (high lag)
Review by Sweclockers U2717DA version with adjustable arm
Review by TFT Central (high lag)

Spoiler (hover to show)

The Dell U2717D has worse color presets than the U2715H and many competitors, has decent contrast (900:1), fast pixel response times, but suffers from overshoot ghosting and a 20ms delay.  The U2717D is essentially an overpriced version of the Qnix QHD2730R with a height adjustable stand and better warranty, but worse color presets, overshoot ghosting and no overclocking. 

The U2717D is uses LG's fake frame-less casing which is not actually frame-less.  Frame-less monitors have inner black bezels which decrease the perceived black depth and make dark content look a bit washed out, just like glossy black and matte black bezels do.  Example: notice how light the black letter box bars look compared to the monitors inner black bezel.

The U2717D reviewed by Les Numeriques has lower input lag and better color presets which indicates to me that Les Numeriques reviewed a newer revision.


Dell U2716D

Review by =DEAD=
Review by Hardware.Info
Review by PC Monitors

The Dell UP2716D is the first decent wide gamut monitor Dell has released.  The UP2716D has low input lag and minimal overshoot ghosting unlike its predecessor the U2713H which suffered from excessive overshoot ghosting.  As expected the sRGB mode has locked color controls and is inferior to that of a normal monitor.  The UP2716D is a good choice for those who need a wide gamut monitor, intend to calibrate it, and use it with programs which support color management.  The UP2716D is a waste of money for gaming and regular use (text, email, movies, coding, ect).

Fake frame-less semi-glossy (same coating as the HP 24 Envy I tested; the semi-glossy coating looks washed out in brightly lit rooms and the S2718D looks grainy when viewed slightly off angle) 2560x1440 LG AH-IPS panel with height adjustable stand.  It has negligible input lag, good preset color accuracy and competitive pixel response times for  a 60hz panel.


Dell S2719DM

Review by PC Monitors

The Dell lacks a height adjustable stand and is not VESA compliant, as well as drop or skip frames when overclocked above 74hz when connected to Nvidia graphics cards.  It has fake HDR (lacks wide gamut 8 bit panel with full DCI-P3 color space coverage, local dimming and high brightness), only two HDMI, and the matte coating is slightly grainier than some competitors according to PC Monitors.

Free-Sync (AMD GPU required) works from 56-144hz/fps, eliminates tearing and lag, it is the only AHVA Free-Sync monitor with back-light strobing, and has excellent 1080p scaling which makes it the best all around 27" 1440p AHVA 144hz monitor for PC and console gaming, and watching 1080p content.

*Dark matte grey bezels increase the perceived black depth even more.

Review by Rtings
Review by TFT Central

Very accurate and fully adjustable matte 2560x1440 144hz wide gamut Innolux IPS panel with Displayport, 2x HDMI 2.0, HDR support+, RGB Lighting, 2x USB 3.0 and 3.5mm Audio In & Out.  The sRGB mode must be selected to prevent the 30% wide color gamut over-saturation of non-HDR sources and ensure maximum color accuracy.  The sRGB mode locks the brightness and color controls and leaves the monitor stuck at over 180cdm/2. 

The Balance overdrive setting is the best for 60hz while both Balance and Speed are useful with 144hz, however, the Speed setting adds quite a bit of overshoot ghosting which may disturb even casual gamers and display users who usually do not notice overdrive flaws.  I recommend using the Balance setting for all refresh rates, as well as can't recommend this monitor to those who are upgrading from fast LED PWM Dimming or Flicker Free 120hz+ monitors.  The Balance overdrive setting has significantly slower pixel response times than all five* of the 144-165hz 1440p AUO AHVA (marketed as IPS) panels with G-Sync, however, the Gigabyte is significantly more accurate than all of them aside from the ViewSonic XG2703-GS which was discontinued in summer of 2018.

+It can accept an HDR signal and dsiplay 95% DCI-P3 color, but is less (470cdm/2 with HDR on) than half as bright as the HDR standard brightness of 1000cdm/2, and lacks local dimming result greyish black and washed out dark content due to the 1100:1 contrast ratio.  Bright bias (light placed behind the display) or room lighting can help trick the eyes into perceiving greyish black as true black.

Fully adjust-able matte 2560x1440, 165hz wide gamut/HDR IPS panel with AMD Free-Sync, Displayport, 2x HDMI, 2x USB 2.0 and 3.5mm Audio In & Out.  The FI27Q over-saturates the color of SDR (HDTV/REC 709 & sRGB) out of the box by over 30% since it has a wide gamut panel which tries to cover the DCI-P3 (HDR) color space, but it is very accurate preset gamma and color (previous 3x hyperlink source=PC Lab PL).  The sRGB emulation mode of the unit IT Hardware and Tom's Hardware tested are quite accurate while the FI27Q's sRGB mode Belgium Hardware tested significantly reduces the gamma and RGB level color accuracy (Standard versus sRGB), as well as looks washed out since the sRGB mode's gamma is too low.  The FI27Q has negligible input lag and less (2.7%) overshoot ghosting than the AD27Q (20%), but slower pixel response times resulting in more color streaking or ghosting.
