Silly question perhaps but have you tried changing it back to 1080p in the SETTINGS?
For some reason my SMP doesn’t properly detect 1080p on my HDMI connected Panasonic TV and only shows 720p at boot. I’ve changed it to 1080p myself in the settings menu but each time my SMP crashes or I do a reset it reverts back to 720p.
Is there even an option for 480p? I will have to check that myself later!
