Beautiful display, 4k 144hz output with HDR600 is fantastic. The 16 local dimming zones are mediocre at best however, and some users may prefer to switch local dimming off as you're limited to 16 vertical strips of brightened area, which looks terrible when you have a single bright point on the screen that doesn't extend vertically.
However, I had major issues trying to mix HDMI and DP. The screen kept going black as if disconnecting, yet was still detected in Windows 10 display properties (and the desktop didn't re-arrange as if it had disconnected). This doesn't seem to have anything to do with settings, which can help reduce frequency of this error but the only thing that ultimately resolved the issue for me was using only Display Port connections for my multi monitor setup. Many other users of this monitor appear to be having similar issues, one poll of 40 users suggesting 50% of them.
Next, when you switch source on this display it disconnects the monitor, causing that device to rea-arrange the desktop as if it had been unplugged. I've never seen this behaviour before and since I switch source very frequently it's a very annoying drawback as Windows takes a while to re-configure multi-monitor and sometimes doesn't always do it correctly.
Finally, I had to send it back after a week as it had a TAB failure. I'm currently waiting on the replacement to arrive, which with the shortage of stock at the moment on this model means in September I'm still waiting to use the monitor that I paid for in July.
