The gaming osd is very nice. And I hit around 780 nits in HDR. 130 nits higher then my previous OLED. I have proper measuring equipment for that. Overall happy with the upgrade.
Set your PC to 60 hz. With OLED Motion Pro to off.
Then load ufo test in Chrome. Firefox has issues.
Look at how blurry it looks.
Then Set PC to 120hz. And Refresh the UFO test page so that it detects 120hz. If you don't then the page will stay at 60. A marker will tell you if the page is at 60 or 120.
Then set OLED Motion Pro to High. And look at how clear it looks. Its exactly like how a CRT looks. Compare 60hz Motion Pro off. And 120hz with Motion Pro high.
And also compare 120hz with it off and High. And 60 hz off and high. 60hz at high makes it clearer. But it's nothing compared to 120hz at high. And at 60hz it's too flickery. But at 120 flicker is not bad.
I set an alarm today to try it but didn't get the time, I'll see if I can tomorrow. I'm just a bit afraid of changing settings as it took some time to get everything right.
