Best TV for gaming? What should I put attention on?

I own an Xbox one X and now I prefer to play comfortably from the couch instead of at the desk.

However, my budget is low and I would most like to get the most picture quality out of what is possible with a TV in the price range.

My budget is 600 euro and I do not know much about the area, but I picked out a few devices.

I would be glad if someone who knows his way in the area could give his opinion.

So for gambling TVs are generally poor (worse than gaming monitors) due to the high response time. So if you are looking for a reasonably good "gaming TV", then always pay attention to the response time. The lower, the better. I looked at your left and did not find any information
