It has been co-developed with Counter-Strike pro gaming legends to bring you a gaming monitor like no other – from the attentive designs to the exceptional functions. The XL2720Z demonstrates BenQ's true belief that "gaming is in the details". For picture adjustments, see LightBoost FAQ at. XL2720T Lightboost color seems better with drivers 320.18 If you don't have a Titan/780, then Lightboost often benefits older games a lot more (try source engine games, Quake Live, test with both VSYNC ON, and with VSYNC OFF), as it behaves like a 120Hz CRT and needs 120fps to make it sing. Finally, it will be easy to enable/disable LightBoost - with a hotkey shortcut! - even on multiple monitor setups. Some good news - ToastyX is developing a new LightBoost utility (I'm beta testing) that makes it easy to enable/disable. mdrejhon - Tuesday, Jlink BTW, great to recognize the attention needed because LightBoost apparently now sells a significant fraction of 120Hz monitors ever since the extreme enthusiast community figured out how to use it (without needing 3D).Whatever the cause of it, the power use of the BenQ is very low. I have a feeling the BenQ benefits by having a lower resolution 27” panel than most of the 27” monitors I’ve tested, but with the small number of data points I have so far that is all conjecture at the moment. Other than the Acer touchscreen model, the BenQ is the most efficient monitor for which I have calculated the Candelas per Watt number, which takes into account screen size, power use, and light output to normalize the data. The BenQ XL2720T also does well on power usage, consuming very little at maximum or minimum backlight levels. If you aren’t trying to go below the 95 nits light level that I saw on the white testing, you will get a contrast ratio right around 820:1 from the XL2720T. The lower number we saw on the sRGB calibration was due to targeting a light output level below what the monitor can do natively. The contrast ratio on the BenQ comes out at right around 820:1 at maximum or minimum light level. It isn’t a bad number, but black level is really all about contrast ratio and on its own doesn’t mean much unless we also know the white value. The black level was fine on the XL2720T, though not exceptional as TN isn’t known for being great at blocking out light. Anytime you lower the peak of the LUT, you then start losing contrast range, which is why we try to get the monitor set as close as possible before calibration, or use DDC to have it automatically do it correctly. If we are targeting 80 nits, and the lowest level the display can natively do is 93 nits, then the video card LUT has to be lowered to bring that brightness down. The lowest white level I could get was 93 nits, which helps to explain the contrast ratio issue on the sRGB test. No one would ever use a display this way, so it’s a bit impractical for me to measure them this way. It might be possible to set the contrast to 100 and record a higher number, but with that setting the top white shades, from around 230 until 255, all blend into a single shade. BenQ says that the maximum light output of the XL2720T is 300 nits, but the most I could record is 252 nits while not totally crushing whites.
