I bought this monitor 2 days ago.
1) It doen't have Display Port 1.3, so for 4K 60Hz i had to go only via HDMI 2.0.
2) At the beggining i had some burn in effect. After the setup with lower brightness it was ok.
3) The Monitor suffers from Frame Skipping guys. I tried to play FIFA 18 and i noticed something like hiccup every 3-4 seconds. I tried the in game settings and settings from nvidia control panel, but nothing changed. Then, i tested the monitor with online frame skipping software and unfortunately, i verified the frame skipping problem.
This is basically a useless product. Frame Skipping? Why? You have to married with lag with this monitor. I don't ask for low input lag, or gaming features, but frame skipping is very serious situation.
I had some dead pixels btw.
Luckily, the store was refunded me.
I was very scared. I thought I had lost my money and that I had to stay with it.
Stay away from this monitor. If you are using Editing Sofware only like AutoCad or something go for it. If you play even casual games is a very very bad choise.
Thanks!
