I have a job with a number of standalone TVs with nothing but a Roku Ultra connected.

Frequently, multiple TVs will not sync with the Roku players upon power up and the Roku indicates an HDCP2.2 error. Rebooting the Rokus resolves this. These seems to happen more when a new app is brought online.

All devices are 2022 models. Any insight as to why this would be happening and what the resolution may be (hopefully not EDID read/writer).

Thanks!

I've been having that issue with Roku units for years and it doesn't matter what configuration (TV only, AVR, etc.). I've never looked too deeply into a fix as it is infrequent enough that a reboot takes care of it.

I am trying the following to see if it helps:

Set the Roku video display to 4K HDR rather than leave it on Automatic. I am a bit unclear on how the Roku deals with this setting and behavior.

Set the Advanced display settings to turn off Auto-adjust display refresh rate and set HDR to always on.

I will report back.

there has been threads about this. i have always had these issues especially w avrs

Just had same issue with fire stick. Changed res to 1080p. So far so good. Usually my problems are with rokus and streamers through a receiver they always have issues with this particular fire stick was in denon receiver

We always set resolution to a specific setting NEVER auto. Have ZERO issues with any type of Roku.

Same

interesting add?? never tried this. usually keep on auto, maybe thats why? what do you set it too?
