Summary: This sits nicely next to my MacBook Pro (which usually runs Windows 8.1). I dialed the resolution back slightly so I could read easier, but it shows full resolution clearly. Bear in mind when you get a high-pixel monitor, sometimes some of the interfaces don't show full resolution on HDMI. This one does. Highly recommended.
Summary: It took me a couple of days of tinkering with this monitor and my Video Card settings to figure out how to get it running to its full potential. Running this monitor using a Sapphire R9 290X 4GB Video Card with the reference cooler. I originally was getting very poor graphics performance when running any game using this monitor at max resolution.
Summary: I had been seriously considering buying the IMac 27" Retina desktop machine since its announcement but decided to give this monitor - hooked up to my 2013 MacBook Retina - a try instead. It's only been twenty-four hours but so far this monitor has exceeded my expectations and I've saved a couple of thousand dollars.
Summary: I don't have time to leave a long review but PLEASE READ. All the posts about bad color, etc are people who have unreasonable expectations. For the price, this thing is amazing. No your not going to get high end IPS level color representation, but for games and general use, it's great. The stand does adjust a bit, and it's fine. I'd rather not have to pay more because it has some fancy stand.
