Xbox One S no picture?

I have connected my Xbox One S to my monitor and can play well there. However, it runs with DVI and I use an HDMI to DVI adapter to play on the monitor. Now I wanted to play on a TV that also has HDMI, but there's no picture! I then set the HDMI priority in the display settings. Then I had a picture on the TV, the only problem was that it only worked on a very low resolution. (640P I think)

How can I play on 1080P on TV again?

Please answer quickly

Do I know other Lankabel use and often off and on just waiting in the place that helps. It's pretty annoying isn't it? Last time a year ago I thought they patched it

Please note if you have a monitor with a higher setting and have adjusted your Xbox accordingly, this will not reset on the TV. (if picture settings are set to DVI or HDMI) put your Xbox back on the monitor, set the Hz number to 60, the resolution best to the lowest and switch off all other features ("allow" 4K, 3D, HDR, etc remove all check marks)

I've already tried everything. Doesn't work

Does that just have to be plugged in or to a dlan or something?

Unfortunately not working but thanks anyway
