Hello, I am using the translator to be able to write this. I recently purchased a TCL 4k TV, but when using apps like Star+, Disney+, Netflix, Amazon, they all show 480p resolution and I can't change it since there is no option in settings. I know they run at that resolution, and I can't upload it either, even if I put the quality preset in the apps.
Youtube I can force 4k resolution and it looks great, but I can't watch ESPN on Star+ at more than 480p
I have a TCL 65" 2022 model no issue with resolution at all, if you've tried resetting the TV, then I'd contact TCL direct
