Monitor arrived and all setup. The screen looks mental, the blacks, 4k it all looks glorious.
I updated to the latest firmware which gives Dolby support which I'll do some research on as I'm not sure what it is.
Played a few games briefly, Witcher 3 with HD rework Mod looked stunning and looked like a modern title.
Path of exile really impressed me in a dungeon with the black colours and red bloody orbs on the ground that glowed.
Performance hasn't taken much of a hit and to my suprise I had AA completely off and thought it looked great so will leave it off and enjoy the better performance.
4k OLED I really didnt think it was going to be a big jump in picture quality. I can safely say it's a night and day difference and has enhanced my games by a huge amount.
