TV won't switch to HDR after June Update

When playing any 4k content my TV no longer switches to HDR mode and all colors are washed out.

Tried force 422 but that did not help.

Please use the log uploader in MyOSMC so we can get the big picture.

Here you go.

Thanks. Can you post mediainfo for the file you are trying to play, please?

None of my 4k files will work but here is the one from the log.

Thanks. I think the basic problem is you have quantisation range set to full. It should be limited.

Are you sure the TV is not switching to HDR mode?

My TV would always display the HDR logo when i played files before and the colors seem washed out now.

I might try and bypass my Yamaha receiver when i get time to troubleshoot more.

I have not changed any settings recently. It has always been on full but i will try switching it and see what happens.

Thanks for you help.

After more troubleshooting I have it figured out. It ended up being something weird with my TV.

I pulled the plug and let it reboot and now my HDR is working fine again.

Sorry to waste your time. Thanks.

No time waste. This may benefit other users with a similar display in the future.
