Apparently this issue has been around for a few years.
i set my display type to 4K HDR, but roku wants to keep changing to Automatic.
i don’t want Dolby. When the display type changes to automatic it reset my TV to Dolby.
i have a new Sony 4K tv that supports Dolby, but I have it set to custom and not Dolby.
All I want is that the display type stay where I set it
all settings should have a lock, so nothing can change unless the user changes it.
i have tried multiple things to fix this issue, but nothing works.
i have found that automatic on a lot of devices just cause problems.
please fix this. It is very annoying.
I don't know if this will help your sutuation, but it seems to be related:
When the "HDMI handshake" between the Roku and the TV or other display doesn't indicate the display device supports the current Roku display settings, by default the Roku's "automatic recovery" kicks in and switches the Roku back to "auto detect" mode. If the display (or an intermediate device you are connecting through) incorrectly reports during the handshake that a support capability you have successfully set the Roku to use is not supported, this can cause the Roku to switch back to "auto detect" when you don't want it to.
You can currently turn this "automatic recovery" feature off via a "secret menu" option.
[CAVEAT: "secret menus" are not officially supported and may be discontinued at any time.]
To access the ROKU HDMI secret menu:
Press Home five times.
Immediately press Down, then Left.
Press Up three times.
The HDMI secret menu should open.
Click on "disable automatic recovery" to turn it off.
