H9000 burn in?

I asked a colleague about this and he said: "TFT and LCD displays don't have burn-in issues, but they can develop image persistence issues that go away after ~48 hours unpowered"

The backlight might also have a limited lifespan, but using the screen dim feature (which can be enabled in the Preferences page in SETUP mode) should extend it.

Are you using the screen in H9k constantly?
I use mine occasionally but mainly using emote now.
So have mine setup to reasonable brightness and then it dims to zero after a couple minutes or so.

I had the same concern as you so asked your same question and now use as above to make the screen last longer

Yes, the range is from 0 to 10. However, the difference between 0 (off) and 1 (on) is faaar too great for fine adjustments. 1 should be much darker.

well can be set to dim and using the brightness and dim vals have it going dark and i actually can’t see anything on the screen so i think it’s off?
