I can't figure out how to make the image setting stick. I set it to "Cinema" but after a few seconds, the projector does something, not sure what, and the brightness of the image is cut in half. If go back to image setting and set it to "Cinema" the image looks good again. But then after a period of time, from almost instantly to 20 seconds or so, the image brightness is again cut in half.
This only happens when I play certain videos from my AppleTV 4K, "Game of Thrones" and "The Madalorian" are the ones I have tried. Other videos like "Rougue One", and "Aliens" look great. Broadcast channels from the Comcast cable box look great.
What I want to to turn off any automatic things the projector is doing and set it to "Cinema" and just have it stick. Can anyone help me? Optoma tech support wasn't too helpful with the suggestion that I send it back because it might be broken. I don't want to send it back on a "might be". | moderator Joined: Mar 28, 2005

I don't have a good answer on this one. I would definitely reach out to Optoma for support on this one and check the UHZ65 owner's thread over at AVS.
There is a chance that when the AppleTV kicks into HDR mode and changes the settings automatically on the UHZ to HDR mode. Contenting being 'dim' is a key factor of HDR material. To get 'specular' highlights, it has to lower the brightness of everything else. Which may not be something which is desired.
That's what it sounds like to me at least.
Disabling HDR content may give you results you are happier with. Or there may be some adjustment which is possible to the HDR settings themselves which leave you with a more satisfying HDR image.

I am having the exact same problem. I just received my UHZ65LV yesterday and spent the day trying to do a basic set up. No matter what I do, the image is always dark and of shifts from darker to lighter, back and forth. It was more stable when connected to my xfinity box but when connected to my apple TV it has tons of problems. To make matters worse, the picture is noticeably darker then my Epson 3700 which it is replacing plus will only sink to 4K at 30 or less. not at 60 despite new wiring and a new receiver. Should I return it and try another brand. I wanted "everything" like usual, Laser, over 4000 lumens and full HD 3D support because I have tons of material Any advice? Where you able to improve the picture quality and brightness on your's thanks | Quote (AV_Integrated on Nov 17, 2020 9:18 AM): I don't have a good answer on this one.
