Excellent monitor

by Jim star star star star star

Had the monitor a week now. Frame and stand are good qaulity and the stand does not get in the way of my mouse or keyboard (I like monitors to as close as possible). Colours out of the box are great and the picture is so much more vibrant than my old VA panel. The biggest difference is going from 144 - 240hz. I noticed the difference straight away and animations and movements in the FPS' I play are so much clearer and better. Tracking targets is noticably easier and when sniping it honestly feels like im cheating. Could not recommend this monitor enough - next nearest 240hz 1440p is almost double the price and its never going to be twice as good as this - not even close. Would highly recommend. OC delivered the next morning at 9am when I ordered it at 4pm the previous day. 5/5
