Danton: You probably have to reboot after changing resolution. There's also a problem of hardcoded DPI which may not make sense for 4K output. I'll check that on my TV. You can always change DPI with an app like: https://play.google.com/store/apps/detai..._dpi&hl=en
Also a screenshot would be appreciated
