I have been using this panel for about a week now myself.... It is my first foray into 4k PC action and has been great so far.... I did not buy perfect pixel option and have noticed 0 dead or stuck pixels.... I typically would choose glossy screens but the anti-glare coating is not bad. Colors out of the box are pretty spot on just eye-balling it and the colors are definitely a tad more vivid than my 1440p IPS I was using prior to getting this. I am using Windows 10 scaling set @ 125% and enjoy it there.... Gaming is great so far although my rig has finally met it's match with it's single 980ti. This unit has an integrated power supply. so no external power brick to hide, has suprsingly good fit and finish with a fully aluminum stand and sleek, textured panel housing and bezel. Out of the box the brightness is set at 50% and is WAY too bright.... I am running it at 26% now and feel it is just about right, just on the brighter side of my preferences, but helpful for color and contrast.
The largest negative is backlight bleeding, mostly on the bottom right corner, a tad in the bottom left and a smidge on the top left.... This was very noticeable at the default brightness, at my current setting I only notice a small amount of the bottom right area on dark screens, which was by far the worst area at default brightness, the other areas are virtually gone at 26%. I did not receive a remote control in the box with mine, but did receive a hdmi cable and US power adaptor for the asian power cable, although I have since ordered a replacement US "mickey mouse" plug power cord from Amazon for 5 dollars to eliminate the dumb US adaptor.
