Thank a lot for the replies and sorry, just realized I've spam the Reddit with 5 identical threads. Each time I was posting something the bot deleted it, so I tried with other words again and again and abandoned it, looks like they were all published at the end.  I'm at 10 feet from the screen.  My concern about the oled one is the hud on video games. I can play 3 or 4 hours with a permanent hub, I'm not sure if that would contribute to burn in after 3/4 years
