Re: Roku Ultra causes blank screen on Samsung TV

Starting a new thread because I now have a new problem.I had unplugged the 4802 to plug in the 4850 to try it and then my TV went black and I will not risk that again so I returned to 4850 but now I’ve plugged the 4802 back in and  I can’t get it to play the 2160 resolution that definitely applies to the videos I’m trying to play because it did before and when I go to my Apple TV player it plays in 2160, this particular one is only going up to 1440, this particular video.  I have checked the resolution setting and it is
automatic (4K HDR 10+) which I believe is the correct setting for Samsung.  
I have confirmed that 4K is working in the prime app and the Hulu app on the Roku so the TV is not the problem.I did Google search it says to go to video settings in the settings of the YouTube app but there is no video settings in the settings of the YouTube app on a Roku or for that matter on the Apple TV+.  
What do I do? Yes I have unplugged it and plugged it back in, yes I have checked the update software for the Roku player itself and the YouTube app.Roku player is software version 15.0YouTube app version web_20251026_18_RC00

    More bad news, the YouTube TV viewport/frames is 1920×1080 and the current/optimal Res is 3840×2160 which means I’m really only seeing it in 1080 P, when I go to the Apple TV+ app player the player it shows 3840×2160 for both viewport and current optimal Rez.  This is on the World Series 4K version and it’s on YouTube TV   

     

    So the Roku player is definitely messed up 
    😡

    The YTTV app's resolution settings are only available during playback via the timeline OSD and default to Auto, and require manual configuration if Auto sets a low/lower resolution:

    During playback (4K content preferred):  Down (OSD popup), Down, Select 'HD', select 2160p HDR (or 1080p/720p Enhanced for 1980p/720p content that supports it)

    NOTES:

    • 1)  Its best to do this with a 4K (2160p) Live Channel or DVR recording as that will also manually configure 1080p/1080p Enhanced or 720p/720p Enhanced for 1080p and 720p channels respectively.
    • 2)  The resolution will reset to Auto (and a lower res) if there are 1) network problems 2) App updates (platform layer or UI layer) - you then have to manually (re)configure resolution (preferably with a 4K channel/recording due to above).
    • 3)  A viewport of 1920x1080*2.00 = 1920x1080x2 = 2160p (4K)
    • 4)  All of this applies to the YTTV app on all platforms

     

    The Roku player isnt "messed up" - you need to better understand all of your devices' hardware & software (firmware and apps) that you use for streaming in order to maximize your enjoyment/usage/quality.

      Something is messed up since I’ve never dealt with any of this before ever with multiple TVs and Roku players over many years, it all started when I tried to get that 4850 to work and the screen went black and now all these resolution issues are occurring that did not occur the day before but thank you very much for the information.
