Now I see framerate and display type contributes to issues some have seen with Roku OS 9.2 stuck at 1080p output for 4K. I saw this today for the first time. Here's why.
If framerate enabled, 2160p at framerate sent. Disabled, 1080 60p HDR was noted with auto display detect for 4K HDR 60Hz noted as display type detected.
Set display type to actual native for display and 2160p HDR played fine. Auto detect display type appears broken with framerate disabled. If disabling framerate, set display type to native for your display. Do not use auto detect.
Many have noted that but I haven't seen the framerate settings noted with this suggestion. I could have missed that though. Auto detect display seems fine with framerate enabled. It's worked for me all this time without issue.
Framerate again impacts Disney+ with frequent black screen transitions when jumping around in content in submenus with framerate enabled. Didn't matter the framerate of preview not changing from one to the next, each title preview transitioned anyway. This is annoying. I've seen similar in YouTube and ESPN; not just previews, but also previews in CBS app. But latest ESPN update appears to be locked to 60 refresh like Netflix now (I haven't noticed that before). Even that's disappointing; if users are aware of what's causing this, disable framerate if that's too annoying. Why lock the app at 60Hz; that's backwards. Old discussion. Sorry.
For framerate users in Disney+, stay in the main menu for content browsing to avoid the preview transitions. Maybe adding titles to watch is ideal. Update: posted article below to make this less annoying.
Subtitles are an issue if you want them on Roku, it seems. ATV4K has them enabled by default which appears to Disney's intent from an announcement I saw posted. But my Roku Ultra 4660 has subtitles off and I can't enable them.
As backwards as it seems, I tried some native 24p content rendered at 60p from Roku Ultra. Wasn't bad. But considering the ATV4K performance seems working as expected in comparison, I'll use that for Disney+. I do need the subtitles on occasion.
