-Perceived black depth decreasing fake bezel or frame-less casing with an inner black bezel

30-60hz Nvidia G-Sync.  It suffers from bleaching and a weird (inaccurate) gamma curve caused by the contrast being set too high (reducing contrast from 50 to 42 fixes this according to Toms Hardware), otherwise it is pretty much the same as the Asus PG27AQ which has better color presets.

Accurate (excluding the unit PRAD tested which came with very high, black crush causing 2.6 average gamma) matte 4K four sided border-less LG AH-IPS panel with AMD Free-Sync, height adjustable stand, a monitor hood and 4x USB 3.0 ports.

Matte 4K AHVA panel with 98hz (8 Bit +FRC / 10 bit HDR 4:4:4), Nvidia G-Sync, height adjustable stand, 4x USB 3.0, 384 zone local dimming and true HDR color.  Proper color (YcBcr 4:4:4) is only supported up to 98hz.  Image quality is degraded at 99-144hz.

Review by Tom's Hardware (least accurate)

The Acer XV273K has an accurate 144hz (achievable only when connected with 2x Displayport cables) 3840x2160 or 4K matte wide gamut AUO HAVA panel which can cover 97% of the DCI-P3 color space, and can fully cover the sRGB color space to prevent over-saturation when the sRGB mode is available.  It has a fully adjustable stand, a monitor hood, 2x Displayport, 2x HDMI 2.0,4x USB 3.0 and a 3.5mm Audio Out.

The unit tested by TECHSPOT is has slightly too low preset gamma and inaccurate preset RGB Level balance which causes a preset rose-like tint of light greys and white.

+=Variable back-light which increases the contrast ratio.

The Acer XB273K is a lower end, G-Sync equipped version of the X27 and PG27UQ with slightly lower HDR color space coverage, lower maximum brightness (460cdm/2 vs 1000cdm/2), and inferior variable back-ligh dimming since the XB273K only has three dimming zones while the X27 and PG27UQ have 384 dimming zones.

The Acer XB273K has very accurate Standard mode preset  (SDR/sRGB & HDR color modes; color controls are locked when HDR is enabled), 144hz (compressed 4:2:2 YCbCr422 color signal called instead of 8 bit 4:4:4 YCbCr444 @120hz and 10 bit 4:4:4 YCbCr444 @98hz), 3840x2160 or 4K matte wide gamut AUO HAVA panel which can cover 87.65% of the DCI-P3 color space, provide 460cdmn/2 peak brightness, and can fully cover the sRGB color space to prevent over-saturation when the sRGB mode SDR Variable Back Light=On) settomg is selected.  It has a fully adjustable stand, a monitor hood, 1x Displayport, 1x HDMI 2.0, 4x USB 3.0, 3.5mm Audio Out and Nvidia G-Sync.

The Acer XB273K, X27 and Asus PG27UQ all have over a frame (17ms) of input lag at 60hz, and low (<5ms) delays at 144hz.

Reading the monitors included manual and/or PC Monitors and Tom's Hardware's review is necessary in order to properly understand how to use a wide gamut monitor, and fully make use of all its features such as the back-light dimming (SDR Variable Back Light), and sRGB mode (SDR Colors sRGB) to prevent wide gamut color over-saturation.

Fully adjust-able, matte, 120hz (144hz with 2x Displayport cables at 4K) 3840x2160, AHVA/IPS/PLS panel with AMD Free-Sync (xx-144hz range) with 2x Displayport 1.4 (2x DP required for 144hz), 2x HDMI 2.0, 4x USB 3.0, and 3.5mm Audio Out.  The Acer is quite accurate, but does not really support HDR due to the lack of local dimming and the low 81% DCI-P3 color space coverage.  The default Normal overdrive setting provides very fast and overshoot free pixel response times at 60hz and 120hz, and at 120hz the higher Extreme overdrive setting provides negligible input lag and fast pixel response times but with a bit of overshoot.  The HDR (DCI-P3) mode is mediocre and best left off due to the low brightness and DCI-P3 color space coverage, and lack of local dimming.

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 aside from a very minor blue tint and gamma dip at 10% grey.  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.
