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

Try cycling through the available display modes.

If your Apple TV won't turn on - Apple Support

• On Apple TV 4K or Apple TV HD, hold Menu and Volume Down for 5 seconds, then release. Your Apple TV will switch to a new resolution every 20 seconds. Select OK to choose a resolution or Cancel to quit.

I’d start over from scratch, if video settings alone don’t do it.

Reset or restore your Apple TV to its factory settings - Apple Support

The Apple tv gets also unusable, because all the item on the screen appear and disappear, and I have to unplug and plug again the HDMI cable to get it work again..... IN 640x480

It is, as a matter effect, what I was thinking to do.. but I wanted to try another solution before.
