Conclusion Comparison and Settings
+Ergonomics (connections and adjust-ability) leave the competition in the dust
+Fairly priced (400$)
+Nvidia 3D Vision 2 is less murky looking than regular 3D displays
+3D games are nearly Crosstalk free
+3D Movies are Crosstalk free
+Good 3D mode colours
+Good black levels/contrast in 3D once the contrast is turned up a bit (44-55)
+Excellent black levels/contrast
+Excellent screen uniformity
+Excellent colour accuracy after calibration (250$+colorimeter required) for a TN panel
+Least amount of colour dominance after calibration compared to the VG236H and S23A700D
+Medium-low amount of ghosting @120hz
+Very low input lag
+Matte screen prevents reflections
-Disappointing color presets vs. the Samsung S23A700D and Asus VG236H
-Purple colour dominance out of the box, minor purple tint after calibration
-Ghosting @60hz: both AMA Settings produce obvious ghosting
-Ghosting @120hz: the overdrive (AMA) is poorly implemented vs. the VG236H and S23A700D.
-Ghosting: The poorly implemented overdrive prevents the BenQ from being a CRT replacement
-Anti-Glare coating makes whites and light colours look grainy and reduces color vibrancy
-Anti-Glare coating creates an annoying screen door effect in 3D games and movies
-Dark brightness strip near the bottom of the screen
-TN panel=Poor viewing angles and gamma shift
Over all, the BenQ XL2420T is a great, but flawed monitor. In terms of ergonomics, the BenQ XL2420T has it all and leaves the competition in the dust, yet still remains competitively priced. Fantastic ergonomics can only get one so far though, and the BenQ XL2420T falters in terms of out of the box image quality compared to the Asus VG236H and Samsung S23A700D. The XL2420T's default colours are "meh," out of the box due to the poor gamma, which makes colours look washed out, and it suffers from a strong purple dominance. The medium anti-glare coating reduces colour quality and sharpness even further, but it does do a great job of preventing reflections.
The BenQ XL2420T is a near input lag-less display and beats out the Samsung 120hz displays and ties with my Asus VGH236H when measured with the SMT Tool 2.0. The XL2420T is an extremely responsive display, I doubt even the most hard core CRT gamers will take issue with the XL2420T's very low input lag.
However, CRT gamers may take issue with the slower pixel response times. When it comes to 60hz performance, the BenQ is left in the dust by the Asus VG236H and Samsung S23A700D. There is noticeable smearing and streaking with AMA OFF @60hz and strong dark and light overshoot when AMA is ON.
@120hz The BenQ XL2420T performs quite well, however it is the slowest 120hz display I have used, those being the Samsung 2233rz, Asus VG236H, Samsung S23A700D and Samsung S27A950D. Most gamers won't see any ghosting on the BenQ XL2420T @120hz, but it is there. With the AMA OFF I observed some light smearing and streaking, and with the AMA on I saw some light-medium dark and light overshoot.
The BenQ XL2420T had excellent 3D performance, mostly thanks to the new Nvidia 3D Vision 2 technology which greatly reduces cross-talk and 3D "murkeyness." The 3D colours left little to be desired and all of the 3D movies I tried were completely cross-talk free. Games were also nearly cross-talk free.
My main issues with the BenQ XL2420T were the meh default colours and the anti-glare coating. The Samsung S23A700D and Asus VG236H offer more accurate and vibrant colours for less, however being glossy they are reflective. The BenQ's medium anti-glare coating causes whites and light colours to look quite grainy, and it created a slight screen door effect with 3D content. In my opinion matte coatings, apart from semi-glossy coating should not be used with 3D displays due to the screen door effect.
Flaws aside, the BenQ XL2420T is a great display, and is currently the only 23-24" matte Nvidia 3D Vision 2 compatible display. If you want a matte 120hz display with great 3D performance and low input lag the BenQ XL2420T for you.
If you want better response times and colours, get the Asus VG236H and Samsung S23A700D (3D only works with AMD graphics cards), however their 3D performance is not up to par with the BenQ XL2420T's and they are glossy (reflective).
