The XL2420Z and XL2420G have much better colours than the XL2430T and XL2411Z once set to the Standard Mode.

The Zowie XL2411Z PC Lab tested is vastly superior compared to the unit Les Numeriques reviewed, as did the Zowie XL2411Z reviewed by IT Hardware PL. Both still had terrible preset color accuracy or image quality, but both could be improved to being good for a TN after switched from the terrible FPS mode to the Standard Picture Mode, and after the gamma setting was changed (IT Hardware PL found Gamma 4 to be the best).

The BenQ XL2720Z has much better colours than the XL2430T and XL2411Z, but also needs to set to the Standard Picture Mode to offer accurate colors.

Matte 1920x1080 144hz TN panel with back-light strobing, Displayport, Dual-Link, DVI, HDMI 2.0 and 3.5mm Audio Out.  The XL2411P has abysmal preset color accuracy unless switched to the Standard (unlocked color controls) Picture mode which is the only one which unlocks the color controls and offers passable preset color accuracy.  The XL2411P has negligible input lag, but suffers from obvious overshoot ghosting (default AMA High overdrive setting) or slower pixel response times (AMA Off) versus multiple similarly priced and more accurate TN competitors.

The XL2411P Tom's Hardware tested iss 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.

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.


Review by PRAD

Height adjust-able, matte, 144hz 1920x1080 IPS panel with Displayport, 2x HDMI 2.0 and 3.5mm Audio Out.  The EX2710 has 1100:1 contrast, accurate color when the Standard mode is selected, but slightly skewed and too high gamma starting at 30% white which causes light colors and white shades to be too dark.  The EX2710 has negligible input lag at both 60 and 144hz, the default AMA 1 overdrive setting provides fast and overshoot free pixel response times, but they can be improved by switching to AMA 2, though PRAD did not measure the AMA 2 overdrive, even though they think it is the best setting.
