Best Reviewed Flicker Free 144-165hz 1440p Monitors

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.

Best Monitor Review Sites: Monitor Review Resource Center

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.

Banding

Dawn Engine Banding by Dr NCX, on Flickr

AUO TN panels tend to suffer from very obvious and frankly horrific banding when viewing the above Dawn Engine image, as well as when viewing this 60fps Westworld trailer.  These three monitors all suffer from the same obvious banding when displaying the above image

The BenQ Zowie RL2460, Dell S2719DGF and ViewSonic VX2458-mhd (all tested by me) are free from very obvious banding when viewing both the Dawn Engine image and Westworld trailer both before and after calibration, but I did see minor banding and compression artifacts not present on my AHVA, IPS and PLS panels when viewing some dark content on the TN panels listed above.  The banding is caused by both the source and the monitors.  If I zoom in very closely to the Dawn Engine image on my ViewSonic VP2780-4K (8 bit +FRC 4K IPS with 14 3D LUT) a tiny bit of banding is preset.  Here are the BenQ Zowie RL2460 and ViewSonic VX2458-mhd

When the lights are off a bit of banding is visible, especially on the F2380MX which performs the worst despite using a true 8 bit panel, though the banding is only very obvious when viewing the monitor off angle.

None of the monitors mentioned suffer form obvious banding when displaying this screen shot from The Order 1886 which I display and take a photo of every monitor I test

Abnormalities & Quality Control Warnings

1ms TN vs 4ms AHVA/IPS/PLS

List of cards which support Free-Sync.

These numbers are bogus along with dynamic contrast, 160 degree+ viewing angles, and sometimes even the maximum brightness listed in the display specifications.

TN panels have slightly faster measured pixel response times, but there's barely a perceivable difference, and many of the "1ms" TN panels suffer from obvious overshoot ghosting which can't be reduced (Dell S2716DG), or are not faster than the 4ms AHVA (listed as IPS) panels once their overdrive settings are lowered/reduced to minimize overshoot ghosting.

"1ms" Asus MG248Q @60hz vs "4-8ms" AHVA/IPS/PLS @60hz

I can cite many other sources to prove that "1ms" TN panels are not significantly faster than "4ms" AHVA panels, but there's no point. Usually the only time "1-8" ms times should be believed is in the case of "5ms" TN panels since they tend to actually be significantly slower than "1-2ms" TN panels.

AHVA/IPS/PLS vs VA Panel Image Quality Differences

AHVA/IPS/PLS vs VA Panel Image Quality Differences

Curved VA panels have less sharp text than AHVA/IPS/PLS and TN panels:

IBXT Curved C24FG70 VA Text Blur Analysis
PC Monitors Curved VA Panel Text Blur Analysis

TN panels suffer from vertical gamma shift: their colors and shades are uneven from top (top quarter is too dark) to bottom (bottom half is washed out), as well tend to have more banding, and always have vastly less wide, or more restrictive viewing angles, though all LCD panel types look the worst when viewed from above, or looked down at.

VA panels suffer from horizontal gamma shift which causes the sides of VA panel to be significantly lighter or washed out compared to AHVA, IPS and PLS panels. VA panel gamma becomes lower, and colors and shades become more washed out the further away from the center.

AHVA/IPS/PLS vs TN Panel Image Quality Differences

All TN panels have very restrictive viewing angles and suffer from vertical gamma shift, therefore all TN panels have bad image quality. AHVA/IPS/PLS panel glow is not a problem if viewed correctly, and not in the dark with the brightness cranked:


Since TN panels suffer from vertical gamma shift, their colors and shades are uneven from top (top quarter is too dark) to bottom (bottom half is washed out), as well tend to have more banding, and always have vastly less wide, or more restrictive viewing angles, though all LCD panel types look the worst when viewed from above, or looked down at.

It does not matter if one sits directly in front of their TN panel (correct way to view a TN), or how much one pays, especially since the majority (excluding Dell S2716DG & S2719DGF) of the most expensive 27" 1440p TN panels use grainier/sparklier matte coatings than AHVA/IPS/PLS panels. Calibration can vastly improve inaccurate TN panels, but a TN is a TN, and all TN suffer from obvious vertical gamma shift.

Acer XB271HU (AUO AHVA) vs Dell S2716DG (AUO TN):

Calibrated but connected to a PS4 so there's no gamma correction; both monitors have non-linear and low-ish gamma below the target of linear 2.2

Are 27" 1440p TN panels Better? No

I reviewed the Dell S2719DGF (144hz 2560x1440 8 bit AUO TN from 2018) which has better image quality than the S2716DG (144hz 2560x1440 8 bit AUO TN from 2015) , but has worse image quality than the BenQ Zowie RL2460 since it can properly cover SDR (HTDV/REC 709 & sRGB) color spaces while both Dell monitors over and under-saturate colors, as well as can come with low preset gamma (the S2719DGF I tested came with sub 2.0 preset gamma):

BenQ Zowie RL2460 vs Dell S2719DGF Calibrated Color Gamut Comparisons::

BenQ Zowie RL2460 vs Dell S2719DGF Color Gamut Comparison by Dr NCX, on Flickr

The BenQ Zowie (6 bit +FRC AUO TN panel) can fully cover both SDR color spaces (HDTV/REC709 & sRGB) without any under-saturation and only a bit of under-saturation while the Dell S2719DGF significantly over and under-saturates some colors compared to both the HDTV/REC 709 and sRGB color space, and does so significantly more when un-calibrated.  When un-calibrated it significantly over and under-saturates some colors compared to both the HDTV/REC 709 and sRGB color space.  The top left side of the triangle (HDTV/REC 709 color gamut) falls short resulting in the under-saturation of blue and medium to dark greens. Medium to light greens, yellows, oranges and some reds are all over-saturated, a phenomenon typical of AUO panels, including both their 27" 2560x1440 and 32" 3840x2160 AHVA (more balanced or pure) panels which also over-saturate the same colors resulting in green and yellow tints to browns, greys and whites, even after calibration.

Keep in mind that the S2719DGF is calibrated and has its gamma fixed in the below comparison versus being too low out-of-the-box and significantly more washed out.  Click here to see comparisons of the Dell pre-calibration or un-calibrated versus calibrated to see what a unit with low-preset gamma looks like.

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 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 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 Samsung C27HG70 is more accurate than the Monoprice 33822 QHD, and the Samsung has a semi-wide gamut panel with good HDR color space coverage (95% DCIP3), back-light strobing, a properly functioning and accurate sRGB mode to prevent over-saturation of non-HDR content, and has a perceived black depth increasing dark matte grey bezel versus the Monoprice's fake bezel/frame-less casing's inner black bezel.  The Samsung offers a perceived black depth increasing matte grey bezel significantly better HDR support than the AC 273QCX which uses a fake bezel/frame-less casing with a perceived black depth reducing inner black bezel, but has faster pixel response times and is completely PWM free.

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.

The AOC 273QCX uses a curved 2560x1440 144hz semi-wide gamut and matte VA panel with Nvidia compatible (requires 10 series or better) AMD Free-Sync, 2x Displayport, HDMI 1.4 (75hz 2560x1440), HDMI 2.0 (144hz & Free-Sync support), HDR 400, RGB Lighting, 2x USB 3.0, VGA and 3.5mm Audio In & Out.  The Game Mode 1 and 2 presets offer the most accurate colors, but over-saturate some by over 20% since the 273QCX uses a semi-wide gamut panel.  AOC included a fairly accurate sRGB mode which prevents over-saturation, but locks the color controls.  The AOC claims HDR400 support, but lacks a full 10 bit and wide gamut (91.3% DCI-P3 coverage) panel with 1000cdm/2 or nit brightness (it can output 400cdm/2 as advertised) and local dimming to provide real HDR, which is to be expected from monitors under 1300$ US.  The 273QCX has a very low 8ms delay (SMT Tool measurement) and fast pixel response times (for a VA panel) without obvious overshoot ghosting.

Curved VA panels have less sharp text than AHVA/IPS/PLS and TN panels:

3.) Asus PG279QZ (60-165hz Nvidia G-Sync) AHVA

7.) AOC AG273QCG (30-165hz Nvidia G-Sync) TN
8.) Asus PG278Q (30-144hz Nvidia G-Sync) TN

*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.

I'm not sure if the HP 27 Omen (more information and comparisons) suffers from the same dark scene banding as the Dell S2417DG and S2716DG, but it is more accurate than the AOC AG273QCG and Dell monitors which is why it is ranked higher.

The AOC AG273QCG has fairly linear gamma and a semi-wide gamut panel which slightly over-saturates colors, but has strong preset green tint (Belgium Hardware) and may come with low (700:1) contrast which is normal for curved TN panels.  While flawed, the AOC offers better image quality than the Dell S2417DG and S2716DG which suffer from horrific dark scene banding, overshoot ghosting (S2716DG), and similar contrast and accuracy flaws.

The Asus PG278Q comes in last place because it is very expensive, uses the grainiest matte coating used by a 1440p monitor since 2011, often comes with pathetically low average gamma (1.7 gamma average=washed out colors) and has many quality control and functionality related issues.

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.

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 CQ32G1

Review by Belgium Hardware and Measurements by Belgium Hardware
Review by Playwares (Set Gamma to 3)

Matte curved 2560x1440 144hz VA panel with a Displayport, 2x HDMI and a height adjustable stand.  It's far less accurate and has half the contrast ratio (2,500:1) as the 1080p C32G1 (5,000:1) which also has slightly faster pixel response times or less ghosting the the best overdrive/response time setting (Medium) is used.  Playwares unit came with slightly too low preset gamma (2.05 average) which was improved by setting the Gamma to Mode 3.


AOC AG322QC4

Added the Review by TFT Central

Matte curved 2560x1440 144hz semi-wide gamut VA panel with a height adjustable stand, 2x Displayport, HDMI 1.4, HDMI 2.0, 2x USB 3.0 and 3.5mm Audio Out.  The AOC is fairly accurate (full sRGB color space coverage with >20% over-saturation), has average contrast for a  VA panel (2,200-2700:1; 2275:1 after TFT Central's calibration), negligible input lag and decent overdrive (for a VA panel) at 144hz when the Strong overdrive setting is enabled which without adding obvious overshoot ghosting, drastically reduces the pixel response times which greatly reduces VA smearing and streaking.  The AOC is a very poor choice for 60hz console gaming since it has  slow pixel response times at 60hz regardless of which overdrive setting is selected, and either suffers from very obvious VA smearing and streaking, or obvious overshoot ghosting if the overdrive setting is turned up.

Review by PRAD (<700:1 contrast)

Semi-wide gamut, curved, matte 165hz 2560x1440 AUO TN with Nvida G-Sync (30-165hz range), with a fully adjustable stand, Displayport, HDMI and a medium matte coating which is normal for 1440p TN panels.  The AOC has fairly linear gamma and a semi-wide gamut panel which slightly over-saturates colors, but has strong preset green tint (Belgium Hardware) and may come with low contrast (PRAD).

Review by PRAD (low gamma)

Curved (1800R) matte 2560x1440 144hz semi-wide gamut fake bezel/frame-less VA panel with back-light strobing (120hz MBR), 2x Displayport, Free-Sync (48-144hz range over Displayport & HDMI) 2x HDMI 2.0, VGA, 4x USB 3.0, 3.55mm Audio In and a fully adjustable stand.  The AOC  Belgium Hardware tested came with proper preset gamma while the unit PC Monitors (lowest preset gamma) and PRAD tested came with low preset gamma resulting in washed out image quality which can be vastly improved by setting the Gamma to 3 which increases the gamma to 2.2 which provides proper saturation of colors and shades.  The AOC has an sRGB mode to prevent the wide gamut over-saturation of non HDR (DCI-P3) content, but suffers form a present green tint and has locked color controls.  The Medium overdrive setting is best for 60hz while Strong is the best for 144hz.  The Strong overdrive setting suffers from a bit more smearing than the faster Samsung C27HG70 which has a perceived black depth increasing matte grey bezel.  The AOC is G-Sync compatible, but it flickers and the overdrive setting is locked to Off which reduces the pixel response times and causes very obvious smearing.

Aopen 27HC1R

Review by IBXT

Matte, curved (1800R), semi-wide gamut, 1920x1080 144hz VA panel with a height adjustable stand, AMD Free-Sync, Displayport (48-144hz Free-Sync range), Dual-Link DVI (120hz),  HDMI 2.0 (48-120hz Free-Sync range) and 3.5mm Audio Out.  The 27HC1R has low (1.97) average preset gamma resulting in washed out colors and shades, can not properly, but comes to fully covering the sRGB color space and is inaccurate.  It has a 7ms delay and fast pixel response times (for a VA panel) and minimal overshoot at 165hz.
