Summary: If your video card pushes 60+ fps in all your games but gets tapered by the refresh rate of your monitor, this BenQ XL2420 will do the job nicely. In comparison to your previous monitor, its default color will look different, maybe a bit washed out. But your eyes will adjust, and it wont make much of a difference in the end. It's still a high quality image and excellent refresh rate. I'd recommend it to any gamer.
Summary: I'm very pleased with the monitor. Great picture quality. It didn't quite live up to my expectations - it's not quite "nVIDIA(tm) 3D Vision 2 Ready". Out of the box it's red/blue or red/green ready but for the 3D Vision 2 stereographic display, you need to buy the nVIDIA(tm) 3D Vision 2 Wireless Glasses Kit - not just the glasses. I suppose it's my own fault because I read too much into the description.
Summary: Well guys as other reviews state that playing games (especially FPS) from 60hz to 144hz is just freaking amazing and I just couldn't be any happier with the results on such smoother game-play change in FPS games such as Battlefield 4, Rising Storm, CS:GO, Natural Selection 2, Far Cry 3 and many more.
