Re: roku ultra displaying 1/4 of picture on tv screen

I went to Settings->System->Power. In Power, there was a box selected that said "after 20 minutes of no interaction" the Roku would shut off. I unclicked that box and I haven't had the 1/4 screen picture problem since.

I've had that set since I've had my Roku, since it seemed to almost be an obvious default.  Yet, when it "wakes up", everything looks fine until start any video.  Yea it's alright if/when I reset stuff, but regularly resetting doesn't mean it's fixed if it's ongoing.

Enjoy your Roku experience.

I did this about a month ago

...and ...I suppose it's still under investigation?  Or was it just suppose to make me feel better that "someone cared"?

Re: roku ultra displaying 1/4 of picture on tv screen

Sorry to piggyback here... I have this happening as well, on a 4K Roku Ultra 2020 hooked up to a 1080 Vizio M471I-A2 TV. This only started after upgrading to 10.5, though I only had the 4K for a few weeks prior to that so I don't have a good history. Unplugging the HDMI cable fixes the issue, as does unplugging the power cable. I mostly use the Plex media player app; the screen is normal when not playing anything, but as soon as I start playback the display switches to showing the video playback in "not quite" 1/4 of the screen, upper left, with the remainder in black.

NOTE: I also have a Roku Ultra from 2017 which does not exhibit the same issues, upgraded to 10.5 running on a last-model Panasonic plasma 1080p TV. No issues at all with that, running Plex or other apps. This Roku was hooked to the Vizio above for years with no issues at all.

Re: roku ultra displaying 1/4 of picture on tv screen

So far I haven't had any further issues with the 1/4 screen since I unclicked that box in the settings. I don't think it was "the fix", but it's working. I have noted lately I go to "home" and then shut the power off on the TV/Roku and when I turn the TV on, my screen saver is on when it should be showing the "home" screen. Not a big issue as I can then just go to "home", but obviously there are a lot of bugs with this 4k Roku device. Never had a problem with the streamig stick I had but it was aged and working slowly, hence the upgrade. You'd think Roku would have these issues figured out by now as I've seen some posts on here that were older and describing the same 1/4 screen issue. Happy streaming to you!

Re: roku ultra displaying 1/4 of picture on tv screen

I'm getting this on my 4800X.  It seems to be related to HDMI, because it happens whenever I switch inputs on the TV.  My Roku is on HDMI 1 and my FireTV stick is on HDMI 2 on my LG 4k.

If I turn on the TV with the Roku, so that the TV starts on HDMI 1 (and the Roku), then everything is fine.  If I switch to HDMI 2, then switch back, the video playback on any of my apps on the Roku play in the small window in the upper left.  Even 4K video is reduced in size.  But the apps' user interfaces are fine.  Just the actual video playback is in the small window.

Rebooting the Roku while the TV is on HDMI 1 clears the issue.  I'm guessing because that re-initializes the HDMI connection.

I think maybe the Roku video playback engine needs to do some sort of HDMI connection initialization sort of thing at start of video playback.
