Roku Power-on Resolution issue

I have a Roku soundbar attached to a TCL C Series/C807 2017 65" TV. All software is up-to-date, and I use the sound bar to power-on everything and use the Roku interface. The TV is basically a monitor at this point, but I've attempted to set the resolution 3840 x 2160 at every setting I can find on both devices. 

Unfortunately, about 50% of the time, when I power it on, it'll display the Roku UI in a low-resolution 4:3 aspect ratio (you can't even see all the entire UI). Powering off and back on usually fixes the issue, but it's been going on for a little over a month now...

 

Can you please help?

Re: Roku Power-on Resolution issue

You didnt mention your firmware version:  Settings/System/About

1) Manually configure your display: Settings/Display=4K HDR TV or 4K TV

2) Using the remote:  Home 5x, Down, Left, Up 3x  then select "Disable Automatic Recovery"

3) If that still doesnt work try a different HDMI port on your TV, or a different HDMI cable

Re: Roku Power-on Resolution issue

Thanks for the the info! Issue persists though. :-(

I've set the TV to 3840 x 2160. The smart soundbar is set to auto for display as setting to 3840 x 2160 broke video playback for some titles (audio but no video).

I've also tried "Disable Automatic Recovery". I managed to take a photo of the strange 4:3 low resolution that is randomly occurring. Turning everything off and back on again appears to fix the issue temporarily?
