Re: The 9.4 Update has broken HDR and added input lag on my 2020 TCL 6 Series

Fixed with TCL Support took a bit but this is what worked for me.

1. Turn off your TV.

2. Disconnect all devices.

3. Turn on the TV.

4. Reconnect Devices.

5. Make sure HDMI is set to 2.0 auto in theory should work but just to be safe 2.0

6. Lauch HDR app or game using remote press * change picture mode from Dark HDR to Normal HDR.

TV now works as normal.

This does nothing to fix the issue for me, TCL support made me do this as well. 

The problem has nothing to do with external HDMI devices and the modes that they’re set to, the HDR capable apps on the TV itself have this issue too and there’s no HDMI involved there. 

I blame this all on Roku since this all worked just fine before their update.

I’ve also noticed that the latest update brought back motion smoothing issues on 24p content PLUS a new issue with DTS audio being out of sync.

 

very frustrating!!!

HDR is now broken on my series X as well after this update, and I know it was working before. Roku just put up an article that says 6-series tvs don't support HDR, which means they must have disabled it. What awful companies.

Can you link this article? Or tell me where I can find it?

HDR gaming With a wide range of virtual environments, dynamic animations, and dramatic shifts in per... 

 

I may be reading it incorrectly as I managed to fix mine by unplugging the Xbox hdmi, deleting the input, plugging it back in and cancelling the automatic game mode (what the link is about.)
