apple tv resolution
Hi I own a 4k tv and an Apple Tv, I always use the 4K 30Hz SDR witch is the maximum resolution for my tv. Recently I switched for error in 640x480 60Hz SDR, now it can't change the resolution anymore, even with other resolutions, it woks ONLY in 640x480.
The strange thing is that if I connect the Apple TV to other HDMI port it works in 4k, and if i connect the Mac to the "broken" HDMI port it works perfectly in 4k. So, how can I can get the 4k resolution back to work?
Apple TV 4K, tvOS 13
