Acer XB272Q

Review By Les Numeriqes


Acer Nitro XF252Q BMIIPRZX

Review by PC Lab PL (low sub 2.0 gamma)
Review by TFT Central

Matte 1920x1080 240hz AUO TN panel with a fully adjustable stand, VRB (back-light strobing), AMD Free-Sync (40-240hz), Displayport, 2x HDMI 2.0 (240hz), 4x USB 3.0 and 3.5mm Audio Out.  The Acer is fairly accurate but has high (2.5 average) gamma which causes black crush (loss of detail in dark scenes), though it can be reduced by setting the gamma to 1.8, but doing so sets the gamma slightly too low resulting in slightly washed out colors.  Like many other 240hz TN panels, the XF252Q can not fully cover the SDR (HDTV/REC 709 & sRGB) color spaces.  The XF252Q has negligible or extreme low input lag and the fastest pixel response times out of all the monitors TFT Central tested (oscilloscope measurements) which means it is one of the fastest LCD panels in existence, however it does suffer from a tiny bit of overshoot, especially at 60hz.

The XF252Q PC Lab PL tested came with very low (sub 2.0) gamma,or washed out colors and shades, but came with similarly accurate preset colors (PC Lab PL unit is too blue but accurate like the unit TFT Central tested) and 1000:1 contrast.

Acer XN253QX

Review by PC Monitors


Matte 1920x1080 240hz AUO TN panel with a fully adjustable stand, ULMB (back-light strobing), Nvidia G-Sync (40-240hz), Displayport, 2x HDMI 2.0 (240hz), 4x USB 3.0 and 3.5mm Audio Out.  The Acer is preset to the Standard Mode which is very accurate since it can cover 99% of the sRGB color space, however it does slightly over and under-saturate some colors like most 240hz TN panels, and has slightly flawed gamma since it is slightly too high (2.3 average), but not enough to cause black crush or loss of details in dark scenes.  The Acer has negligible input lag at 240hz (3.26ms measured by PC Monitors with the SMT Tool), as well as top tier and overshoot free overdrive with very fast pixel response times (preset Normal overdrive setting) and nearly as little color streaking and motion blur an LCD can provide without back-light strobing, which the Acer also supports (ULMB) at 120 and 144hz.  The ULMB feature does not work properly at 100hz since it drops back down to 90hz and causes stutter.


ACER KG251QD

Review by =DEAD=

Matte, 240hz, 1920x1080, AUO TN (M250HTN01.3) panel with 40-240hz AMD Free-Sync (Nvidia G-Sync Compatible), Displayport, 2x HDMI 2.0 and 3.5mm Audio Out.  The KG251QD is preset to the Standard mode which suffers from dull or washed out colors and shades since it can not fully cover the SDR (HDTV/REC 709 & sRGB) color spaces (it significantly under-saturates greens; this is common among 240hz TN panels) and has low gamma (1.98 average). =DEAD= does not measure the input lag or signal delay, but does test the overdrive or response times; the KG251QD has very fast pixel response times with minimal overshoot ghosting when the default Normal over drive setting is used.  The KG251QD uses a grainy or sparkly matte coating which dulls color and appears grainy or sparkly when light colors and white are displayed.


Acer XV253QPbmiiprzx

Review by =DEAD=

Matte, fully-adjust-able, 1920x1080, 240hz IPS panel with AMD Free-Sync (48-240hz) Displayport, 2x HDMI 2.0, 4x USB 3.0 & 3.5mm Audio Out.  The Acer can fully cover the sRGB color space (with very minor over-saturation), has 1000-1100:1 contrast, is very accurate out-of-the-box aside from a very minor blue tine (6700k preset color temperature) and http://=https://4k-monitor.ru/reviews/i_zachem_teper_tn_film_obzor_i_testirovanie_igrovogo_240_gts_ips_monitora_acer_nitro_xv253qxbmiiprzx/#elem-6can be further improved by switching to the sRGB mode.  The Acer has very fast pixel response times with only minor overshoot when the default Normal OD setting is used at 240hz; =DEAD= does not test input lag or 60hz overdrive performance.

The Acer has a noticeably grain and sparkly matte coating when viewing light colors and whites.


Acer Nitro XV273 X

Review by TFT Central

Matte 1920x1080 240hz AUO AHVA panel (marketed as IPS) with AMD Free-Sync (48-240hz range), Displayport, VRB (120, 144 and 240hz back-light strobing), 2x HDMI 2.0, 3.5mm Audio Out and  4x USB 3.0.  The Acer XV273 has a native 1170:1 contrast ratio, can fully cover the sRGB color space (with 9% over-saturation), and is quite accurate.  The XV273 has negligible input lag at all refresh rates, and fast pixel response times with minimal overshoot at both 60hz (OD Off) and 240hz (OD Normal) which makes it great for both 60hz console and 240hz PC gaming.

Acer XF250Q Cbmiiprx

Review by PC Lab PL

Matte, fully-adjust-able, 1920x1080, 240hz IPS panel with AMD Free-Sync (48-240hz) Displayport, 2x HDMI 2.0, and 3.5mm Audio Out.  The XF250Q has a 860:1 contrast ratio, very accurate color, but very low preset gamma (sub 1.9 average resulting in washed out colors and shades), and the XF250Q the can not fully cover the SDR (HDTV/REC 709 & sRGB) color spaces like most 240hz TN panels.  Overall it has poor image quality for a TN panel due to the low gamma, low input lag but slow pixel response times, though PC Lab does not provide much much information about the overdrive so I can not properly compare it to competitors until more detailed reviews come out.
