Home screen is fine but HDR turns off when I boot up games, and everything gets too bright

Thank you for the reply JosefLBohorquez.

The odd thing is it just started, everything was perfectly fine up to that point where the problem showed up. The game mode typically displays when an Xbox game loads, there is an indication in the middle of the screen when it turns off and on.

Another odd thing is that MLB The Show 22 does not show this problem. When I load games like Fortnite, Elden Ring then the problem exists.

I tried the disable HDR mode too, that didn't fix the problem. I tried all the typical brightness, contrast settings on the tv and Xbox, but that didn't fix anything.

When I am able, I will try another tv and see what happens, then reply to this with the result.

Haven't tried any other troubleshooting besides what I posted.

Update: I tried the 4K UHD Blu-Ray version of the Martian (brand new), and the same problem occurred. Stuttering and dropped frames with HDR enabled on the XBox, and flawless playing with HDR turned off. Once again, auto brightness was turned off, motion
smoothing features turned off, my Vizio P55-C1 definitely supports HDR10 (it's getting an HDR signal from the XBox when I have HDR turned on) and firmware updates for the TV are automatic.

I seem to have a problem on start up latelying. When you get to the home screen and try to play a game or access anything nothing responds. When I turn my console off the white light at the front of the machine flashes for about 5 to 10 minutes then turns
off. After that when I turn the console back on it works fine. Starting to get fed up with this now.

Found out HDR was the issue. If I turn off the HDR everything works fine. Anyone know why all of a sudden HDR would cause my XBox to dim?

I too have problems Samsung UE49KS8000 upon booting up FH3 HDR kicks in and it's like someone has stuck a smokey film over the screen , I also have a ps4 pro and I have no such issues with horizon zero dawn in 4K HDR .

Really poor that so many people are experiencing this on a wide range of TVs yet Microsoft don't recognise it even though it's one of their biggest selling points on the one s!!!

Wake up MS you've got the Scorpio dropping in several months ,I'm having my doubts especially as this issue may carry over .

To be quite honest FH3 looks absolutely dreadful in HDR and it's put me off playing it !!!

FIX

I found a fix sort of work around. Im on pc. but had the exact same greying washed out look with hdr enabled. it switched my tv to hdr mode but everything looked washed out. playing with the limited settings was a waste of time.

since im on pc ive also had driver issues and win 10 creators update issue. ive spent many hours on this and many emails back and forth to nvidia and calls to sony. nvidia certainly helped on some creators update issues with the latest driver but no fix
for the washed out hdr.

fix-

i have 930c Sony.

after hdr enabled and the tv goes into hdr mode(on sony you cant change from hdr mode while hdr is active). that is important. that way you know your hardware is sending the signal the tv needs in part.

in any case.

i simply unplugged my hdmi cable and replugged in and it fixed everything. tv still in hdr mode and amazing super bright colorful. i actually turned down my color settings. andromeda looked amazing.

now when i run a game that does not support hdr it looks fine in the game actually pretty amazing using the expanded color palette i believe but not really getting the hdr brightness. however when exiting non hdr games the hdr returns to washed out until
i do the unplug deal again. again win 10 itself has hdr mode. im sure xbox and ps4 gui is not hdr(not sure) so you may have to try to unplug after each hdr game is initiated???

something about unplugging and reconnecting on pc is doing something to help.
