Summary: I don't really know what to say about this monitor apart from it's insane. If you play fps then you will be amazed by what 120hz does for your skill, the game is so smooth and it's much easier to aim. Make sure you have a good PC though as you have to be over 120 fps to experience 120hz.
Summary: I received 144hz (2.0 version) which I was after. Monitor is great for gaming, however you can see grid lines for each pixel from very very close. I wasn't happy at beginning as monitor needs some tuning as for me it black colour were too bright, even when much lowered (pale colours).
Summary: Gaming screen, can't say enough good things about this. An excellent screen, works great for gaming and looks amazing. I had problems with a different BenQ monitor and the customer service was excellent, they sent me another monitor very fast and even a new plug.
Summary: Got this monitor today a day early than expected .. thanks amazon .. going to keep this short and sweet .. out of box you will need to adjust the settings to your personal preference but i just youtubed a tutorial so very easy ! it literally took 5 minutes to set up very easy !
Summary: Went all out and built myself a gaming pc. gtx 780 sc acx, 3570k, z77x-ud5h mobo, 8 gb ripjaws and all the rest and this works great with my build. The 3d looks nice and was way above my expectations.
Summary: Bought this primarily for gaming as my old monitor packed up, very impressed with it. It comes set way too bright, so I just googled "Best settings for XL2420T", and set the picture accordingly.
Summary: Love this monitor, No problems here with turning it on as in other reviews. On the box it says 144Hz and can change to this in the settings, also flicker free and 1ms response time. So is it a Revision 2 monitor?
