Summary: Tweaking for games via downloading profiles on BenQs website made fine-tuning a breeze. This is hands down the best monitor I've seen short of a 4k display, even then the 4k resolutions on this monitor look fantastic.
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: 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.
