Acer ConceptD CP7271K

Added the Review by Pro Hardware Hungary and Review by Tom's Hardware to my Best Reviewed Flicker Free 27" 4-5K AHVA/IPS/PLS buying guide.


Matte, height adjustable, 3840x2160 AUO AHVA panel with 384 zone local dimming, with 24-144hz Nvidia G-Sync, Displayport, HDMI 2.0, 4x USB 3.0 and 3.5mm Auido Out.  The Acer ConceptD CP7271K has a native 1100:1 contrast ratio (FALD or local dimming disabled), 90.9% DCI-P3 (HDR) and 96.9% sRGB (when the SDR Color sRGB mode is enabled which prevents the over-saturation of non-HDR content) color space coverage, and very accurate color presets out of the box.  The CP7271K has a low glow AHVA panel, especially when local dimming is enabled, and fast pixel response times; =DEAD= does not test for input lag, but Tom's Hardware did and measured a 31ms delay versus 36ms for the Asus PG27UQ and 39ms for the Acer X27.

The unitPro Hardware Hungary tested is significantly less accurate than the unit Tom's Hardware tested since it came with low preset gamma unless set to the Cool mode (2.19 gamma versus <2.1 for the other modes) which has 8000K color temperature or is way too blue.


Alienware AW2720HF

Added the Review by Rtings to my Best Reviewed Flicker Free 240h-280z Monitors buying guides.

Matte, fully adjust-able, 240hz, 1920x1080, IPS panel with 20-240hz AMD Free-Sync (not G-Sync Compatible), Displayport, 2x HDMI 2.0, 4x USB 3.0, and 3.5mm Audio Out.  The Alienware AW2720HF is preset to the RPG mode which is fairly accurate, but has too high (2.39 average) and skewed gamma resulting in colors and shades being a bit too dark, and loss of detail or black crush when viewing dark content.  The Alienware also can not fully cover the SDR (HDTV/REC 709 & sRGB) color spaces, so it can not display some colors as accurately and vibrantly as it should, even when calibrate, but it does come close to doing so (97%), and can still be considered good.  The AW2720HF has negligible input lag and offers very fast and nearly completely overshoot free pixel response times at 240hz when the Fast  overdrive setting is used, but has slow pixel response times and higher than average (negligible; 15ms delay at 60hz vs typical 9-10ms measured by Rtings) at 60hz which prevents it from being an outstanding console and PC gaming monitor.

The Acer XV273X is significantly more accurate, has superior gradient handling, vastly superior 60hz overdrive, and slightly lower input lag at 60hz (11.4ms vs 15ms), but slightly slower, though still excellent 240hz overdrive.


Asus VG27AQ

Added the Review by Global HD Russia to my Best Reviewed Flicker Free 144-170hz 1440p Monitors and Best Reviewed Flicker Free 27" 1440p AHVA/IPS/PLS buying guides.

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 TUF VG27VQ

Added the Review by Rtings to my Best Reviewed Flicker Free 144-165hzhz 1080p Monitors buying guide.

Fully adjust-able, curved, matte, 165hz, 1920x1080 VA panel with AMD Free-Sync (20-165hz), ELMB Sync (100-165hz back-light strobing) Displayport, Dual-Link DVI (120hz max), HDMI 2.0 and 3.5mm Audiio Out.  The VG27VQ has high contrast (3.900:1) for a VA panel and is fairly accurate, but is slightly too blue, has slightly too low gamma and can not display color as accurate and vibrantly as they should be sinceit can only cover 91.7% of the sRGB color space.  It also does not have proper 8 bit +FRC to simulate a 10 bit signal as advertised since it suffers from a bit of banding when displaying dark colors and shades.  The VG27VQ has negligible input lag, but slow pixel response times resulting in some obvious smearing and a bit of overshoot ghosting when its best Trace Free setting (80) is used.


Asus VG279QM

Added the Review by Les NumeriquesReview by Playwares and Review by TFT Central to my Best Reviewed Flicker Free 27" 1080p IPS/PLS Monitors and Best Reviewed Flicker Free 240-280hz Monitors buying guides.

Fully adjust-able, matte, 1920x1080, 280hz IPS (probably AUO AHVA) panel with back-light strobing (ELMB), Nvidia G-Sync (48-280hz), Displayport, 2x HDMI 2.0 and 3.5mm Audio Out.  The VG279QM is preset to the Racing Game Visual Mode which is very accurate and almost properly covers the sRGB color space, but the unit PC Lab PL came with slightly too low gamma (2.1-2.2) versus the nearly linear 2.2 gamma Playwares and TFT Central measuredThe VG279QM slightly over-saturates greens, oranges, reds and yellows by over 10% but is otherwise very accurate.  The VG279Q supports HDR, but it is best lest off since it lacks almost all of the features required for true HDR, especially in regards to the DCI-P3 color space coverage since it peaks around 80%.  The overdrive is preset to the Trace Free 60 setting which provides the best performance at 240hz whileTrace Free 80 speeds up the pixel response times without obvious overshoot at 280hz.  Trace Free 60 causes some obvious overshoot at 60hz; Trace Free 20 slows down the pixel response times and gets rid of most of the overshoot at 60hz, but is a bit slower than Trace Free 40 which TFT Central recommends.  The VG279QM has negligible input lag according to 2/3 of the reviewers to measured the delay, and balanced and fast overdrive which provides pixel response times which are only slightly slower than the fastest TN panels like the Acer XF252Q.

Les Numeriques measured (middle screen) a 9.7ms delay with the Leo Bodnar device at 60hz which is nearly as low as possible.

PC Lab PL (measured a 27.5ms delay with a high speed camera.  27.5ms is very high for a gaming monitor.  This could be a mistake, a 60hz measurement or a different version of the monitor.

Playwares measured 2-3ms at 280hz and 17ms at 60hz with the SMT Tool.


BenQ Zowie XL2731

Added the Review by Playwares  to my Best Reviewed Flicker Free 144-165hzhz 1080p Monitors buying guide.

Fully adjust-able, matte, 1920x1080, 144hz TN panel with AMD Free-Sync, Displayport, Dual-Link DVI (120hz), 2x HDMI and 3.5mm Audio Out.  The XL2731 has 900:1-1000:1 contrast and is preset to the abysmal FPS Picture Mode which has very low (1.48) gamma resulting in very dull or washed out colors and shades.  Like most Zowie monitors, the XL2731 can be vastly improved by switching to the Standard Picture Mode which provides accurate (2.16 gamma & accurate RGB levels) and good image quality, but I do not know if it suffers from dark content banding since Playwares does not test for it.  The XL2731 under-saturates greens and blue slightly and over-saturates purples, reds and yellows; it can not, but comes close to fully covering the SDR (HDTV/REC 709 & sRGB) color spaces.  The XL2731 has negligilbe input lag at 144hz (3-4ms measured by Playwares with the SMT Tool vs a CRT), a 17ms delay at 60hz and fast pixel response times without obvious overshoot when the default AMA High response time setting is used.  I can't recommend it without knowing if it does or does not suffer from dark content banding, and because it is not competitively priced against the 1080p 144hz IPS panels which have much better image quality.


LG 24GL600F

Added the Review by Pro Hardware Hungary to my Best Reviewed Flicker Free 144-165hzhz 1080p Monitors buying guide.

Matte 1920x1080 144hz TN panel with AMD Free-Sync (20-144hz), Displayport, Dual-Link, 2x HDMI 2.0, and 3.5mm Audio Out.  The LG 24GL600F has passable preset color accuracy (Gamer 1 is the best), but suffers from a preset blue tint and has slightly washed out colors since the gamma is non-linear and too low (2.06 average); Pro Hardware Hungrary measured nearly linear 2.2 gamma, but their unit came with a stronger blue tint (7600k color temperature versus Rtings 6880k).  The 24GL600F has negligibly input lag and very fast (top tier) pixel response times.


MSI Optix MAG272CQR

Added the Review by Global HD Russia and IT Hardware PL to my Best Reviewed Flicker Free 144-170hz 1440p Monitors buying guide.

Matte, curved (1500R), semi-wide gamut, 2560x1440 165hz VA panel with a height adjustable stand, AMD Free-Sync, Displayport (48-165hz Free-Sync range), 2x HDMI 2.0 (48-120hz Free-Sync range), USB-C, 2x USB 3.2 and 3.5mm Audio Out.  The MSI is uses a semi-wide gamut (it over-saturates SDR color by >25%)  but is fairly accurate when set to the Custom Pro mode which also unlocks the color controls and increases the preset gamma and RGB level accuracy.  Unfortunately the contrast ratio is limited to around 2,200:1 (versus 3,000:1 spec) when using the most accurate preset modes, and when calibrated.  Global HD does not measure input lag and the PixerPixAn photo of the overdrive indicates quiet slow pixel response times.  It Hardware PL measured a 4-8ms delay


Philips 272M Gaming

1). Is PWM flickering caused by the panel, or the backlight?

The back-light is controlled by the electronics (think Free & G-Sync monitors with back-light strobing), so theoretically one could modify the software (advanced service menu or EDID...may require hacking without the manufacturer equipment) or put a compatible PWM free board from a PWM Free into a display which uses the same parts like an old Qnix or X-Star monitor.  There are no good displays with PWM so it's not really something to consider unless trying to replace damaged or malfunctioning parts.

Which is the expensive model from EIZO with the better matte coating?

Eizo CS (2560x1440 and up) and CG series.  Curtains are a cheaper and wiser solution since a stronger coating will only make a slight difference; high brightness also helps.

PRAD has macro photos of the matte coatings in their reviews:

AOC U2790PQU (light matte)
EIZO CG279X (medium matte)
EIZO CG319X (grainy matte)
ViewSonic VP2768-4K (light matte)

The monitors you tried all have light matte coatings.

Light matte Acer XB321HK
Medium matte Acer XF240H
Almost-Glossy/low haze HP 25er
Semi-Glossy HP 24 Envy

It's possibly to buy cheap used grainy matte coated 1440p monitors from eBay like the HP ZR2740W

All of them are more reflective compared to older monitors like DELL P2213 or DELL P2417H. I was hoping that newer models from DELL, EIZO or HP are less reflective but videos on youtube are showing that this is not the case.

Most matte monitors use the same light coating now aside from a few mediocre TN panels with grainy matte coatings and very expensive professionally oriented monitors from Eizo.  Control your room lighting (get a less bright ceiling or lamp bulb and/or don't have your monitors facing a lamp or window) to reduce the amount which shines on your displays.  Bias lighting (lights placed behind the display) is the best way to eliminate glare and reflections and increase the perceived black depth.

Asus PA32UCX

Added the Review by NL Hardware to my Best Reviewed Flicker Free 32" 4K AHVA/IPS/PLS buying guide.

Matte fully adjustable 3840x2160, wide gamut/HDR panel with Back-light Dimming, Displayport, Hardware Calibration (Asus ProArt which does not work properly), 3x HDMI 2.0, 2x Thunderbolt USB-C (1 In & 1 Out), 3x USB 3.1 and Uniformity Compensation which reduces the contrast and does not work very well.  The PA32UCX-K is quite accurate (2.14 out of the box gamma is disappointing), but needs to be set to the accurate but too red REC 709 (Tom's Hardware preset color accuracy section) or sRGB mode to prevent the over-saturation of SDR (HDTV/REC 709 & sRGB) content since the PA32UCX-K uses a an HDR-capable wide gamut panel which is preset to use the native DCI-P3/HDR color space, and unfortunately locks the color controls when the HDR mode is enabledAccording to NL Hardware, the PA32UCX suffers from sharpness problems when the sRGB mode is selected.

The PA32UCX-K's color temperature changes and normalizes over a period of two hours when turned on after calibration, as well as suffers from varying color accuracy depending on how long it is turned on and which settings are changed.  The Asus has low input lag and fast pixel response times (for a 60hz non-TN panel) with minimal overshoot ghosting when the preset Trace Free 60 setting is used, and almost full HDR support thanks to the 1152 zone back-light dimming, 1500cdm/2 maximum brightness and wide gamut panel. The PA32UCX-K is a good 60hz gaming and media viewing display, especially once calibrated, but is not suitable for professional use over monitors from Eizo and NEC due to the Asus's improperly working hardware calibration (ProArt) and Uniformity compensation modes, and color-changing issues which occur over time after being turned on, and when settings are changed.

So could it be a defect in the product or bad black uniformity ?

I need to see it to judge properly, but it seems like it should be exchanged or returned.

Fully adjust-able, matte, 3840x2160, wide gamut IPS panel with Displayport, 2x HDMI 2.0, 2x USB-C/Thunderbolt 3, 4x USB 3.1, 1x mini-USB and 3.5mm Audio Out.  The PD3220U is preset to the Display P3 mode which covers 94% of the DCI-P3 color space  over-saturates SDR (HDTV/REC 709 & sRGB) color by 33% and causes black crush due to the 2.6 average gamma.  The User Picture mode unlocks the color controls, provides accurate 2.2 gamma, but also covers the DCI-P3 color space (95%) and over-saturates SDR color by 38%.  The sRGB mode provides accurate color space coverage and gamma, but locked color controls.  The default AMA High overdrive setting provides good results for a 60hz non-TN panel, but =DEAD= does not test the input lag or signal delay.  The PD3220U is a good monitor for those who need to work with the DCI-P3 color space, especially when set to the User mode and calibrated, but there are better proffessional/wide gamut oriented monitors, and much better SDR color space covering monitors available.


BenQ Zowie XL2411P

Added the Review by Tom's Hardware to my Best Reviewed Flicker Free 144hz 1080p Monitors buying guide.

Fully adjust-able, matte, 1920x1080 144hz TN panel with DyaC (144hz backlight strobing), Displayport, Dual-Link DVI (120hz max), HDMI 2.0 and 3.5mm Audio Out.  The XL2411P is preset to the FPS 1 Picture Mode which is fairly accurate aside from the skewed gamma, which becomes even more skewed and causes black crush when switched to the Standard Picture Mode which unlocks the color controls.  The gamma can't be improved with either the Black Equalizer (locked in the Standard Picture Mode) or Gamma controls.  The XL2411P has negligible input lag and fast pixel response times, but Tom's Hardware does not included much information about overshoot ghosting when the default AMA High overdrive setting is enabled, nor do they check for dark content banding so I can't recommend the BenQ.

AOC 27G2U

Added the Review by Playwares to my Best Reviewed Flicker Free 144hz 1080p Monitors and Best Reviewed Flicker Free 1080p 27" IPS/PLS Monitor buying guides.

Matte 1920x1080 144hz IPS panel with a fully adjust-able stand, AMD Free-Sync (50-144hz), back-light strobing (MBR), Displayport (G-Sync compatible Free-Sync), 2x HDMI 1.4, 4x USB 3.0, and 3.5mm Audio In & Out.  The AOC is quite accurate, has high contrast (1350:1), but suffers from a minor preset green tint of greys and whites.  The 27G2U has negligible input lag and very well tuned overdrive when the Overdrive is set to Medium which is the default setting.


Asus VG27AQ

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

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.


BenQ ZOWIE XL2746S

Added the Review by Playwares to my Best Reviewed Flicker 240hz buying guide.

Fully adjust-able, matte, 1920x1080 240hz TN panel with AMD Free-Sync, DyAC (back-light strobing), Displayport, Dual-Link DVI, HDMI 1.4, HDMI 2.0, 2x USB .0 and 3.5mm Audio Out. The has abysmal image quality out-of-the-box and needs to be set to the Standard Picture Mode (1.97 gamma average versus sub 1.8 gamma default) to be improved, though it still can not fully cover the SDR (HDTV/REC 709 & sRGB) color spaces. and have the Gamma setting changed, though I'm not sure if the Gamma 4 or 5 settings provide significantly superior results since Playwares did not test them.  The XL2746S has a 17ms delay at 60hz (common for 240hz TN panels), negligible input lag at 240hz (2-3ms measured with the SMT Tool) and very fast and pixel response times at 240hz (60hz not tested) when the default AMA High setting is used.


BenQ EW3280U

Added the Review by Playwares to my Best Reviewed Flicker Free 32" 4K AHVA/IPS/PLS buying guide.

Matte, 3840x2160, wide gamut IPS (probably AHVA) panel with partial HDR support, a remote, Displayport, 2x HDMI 2.0, USB-C.  The EW3280 offers accurate DCI-P3 color space coverage, but over-saturates the SDR color spaces by over 40% unless set to the REC 709 mode which has high (2.40) gamma and locks the color controls.  The EW3280U has poor HDR accuracy and only partial support since it lacks local dimming, has low brightness and lacks a true 10 bit panel; the HDR mode is best left turned off.  The EW3280U has negligible input lag (2-3ms measured with the SMT Tool) and fast pixel response times for a 60hz non-TN panel wihen the default AMA High overdrive setting is used.


HP Omen X 27

Matte, 2560x1440, 240hz TN panel with AMD Free-Sync with Displayport, HDMI 2.0, 2x USB 3.0 and 3.5mm Audio Out.  The HP is quite accurate, has a true 8bit panel, but 800:1 contrast.  The X27 has negligible input lag and very fast pixel response times when the Level 3 overdrive setting is selected at 240hz (60hz not tested).


LG 27GL850

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

Very accurate and fully adjustable matte 2560x1440 144hz wide gamut LG IPS with G-Sync compatible AMD Free-Sync (48-144hz over Displayport and 48-100hz over HDMI) Displayport, 2x HDMI 2.0. RGB Lighting, 2x USB 3.0 and 3.5mm Audio Out. To prevent the wide gamut (DCI-P3/HDR) panel from over-saturating the color of SDR (HDTV/REC 709 & sRGB) content, the 27GL850 needs to be set to the sRGB mode (which is fairly accurate and has adjustable brightness, but has a preset pink tint and locked color controls.  The 27GL850 has quite accurate and nearly full DCI-P3/HDR color space coverage, but has a slight, though easily reduce-able preset blue tint.  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.


Philips 271E1

Added the Review by Playwares to my Best Reviewed Flicker Free 1080p 27" IPS/PLS Monitor buying guides..

Matte, 75hz 1920x1080 IPS panel with AMD Free-Sync (49-75hz), Displayport, HDMI, VGA and 3.5mm Audio Out.  The Philips 271E1 is very accurate gamma and color wise[/url], but can't fully cover the SDR (HDTV/REC709 & sRGB) color spaces.  The 271E1 has negligible input lag (4-5ms measured against a CRT with the SMT Tool) and fast pixel response times for a 75hz non-TN pane when the overdrive (Smart Response) is set to the Medium setting.

I just hope it doesn't have pixel inversion/scan line/ Interlace pattern artifact

The XG2401 suffers from dark content banding and pixel version, as well as has worse image quality than the newer XG240R and VX2458.

AHVA/IPS/PLS glow should not be a problem with proper display height, display brightness and bright-enough bias lighting.  Another solution is to put non-stick, perceived black depth increasing tape on the bezel. I use this silver Scotch tape on a few fake border or frame-less monitors I own such as the HP 24 Envy (HP 24 Envy with and without tape and HP 25er without and without tape) and 25er.  I've removed and re-taped a few monitors after a few months and not had issues with residue, however I must warn that adding tape to a monitor may void the warranty.

I was hoping to get some advice for my dad. With a 2070S, he'll be using the rig for a workflow, 3D architectural shenanigans, email, and movies. No gaming. I'd like to upgrade him to a dual-monitor or ultra wide setup, so that it feels like an upgrade from his single monitor setup. But without breaking the bank. What are your recommendations for best budget 4K in the 27" or 32" range? To dual up. Or one ultrawide monitor? I found your list for best flicker-free 4K monitors, but I struggled to find an area for best "budget" or "affordable" monitors. Thanks

I factor price into my recommendations, but don't have specific budget picks or cover ultra-wide monitors.  Only 32" 4K VA panels are affordable and dual 27" are much easier to work with.  Also 32" VA panels usually need to be viewed from 3-4ft/90-120cm away to avoid seeing obvious gamma shift and color washout from the sides while AHVA/IPS/PLS can be viewed from 2ft/60cm.

27" 4K text is tiny and looks bad when enlarged by Windows which is necessary if the programs used don't support scaling.  The Philips 276E8VJSB is usually the cheapest, and one of the best 4K monitors, but it does not support VESA.  Philips also sells the 272P7VUBNB for 100$ more with a height adjustable stand and USB-C, but it is untested, though I suspect it is also great since their other 4K monitors are.  The LG 27UL550 (my review) is also very good and has a short, but height adjustable stand and supports VESA mounting.

The BenQ PD2700Q is a great affordable 2560x1440 monitor with a height adjust-able stand and VESA. 1440p is probably a better choice to avoid scaling issues, and cheaper too.  More 1440p options.

your review and prad review report different minimum brightness value

It's normal for monitor brightness and contrast to vary between the same panels, and it's pretty rare for monitors to have <50cdm/2 minimum brightness, but that is a large discrepancy.  I measure brightness and contrast with the User color controls enabled while I'm not sure if PRAD does.  Sometimes monitors brightness varies considerably when the color controls are unlocked or selected, even without modification.  Consider using bias lighting (light behind the display); I made a thread and video about bias lighting.
