Xbox 1X - graphics not in the hand?

Jo have noticed in games like pubg / battlefield, for example, that the edge smoothing (antialiasing) is very weak and I can hardly explain this. Have several videos looked around to escape, see how others do not have such problems and I can't understand that, because someone has a tip? I play at 4k 60hz, however, the smoothing of the edges is extremely weak and makes it look like 720p haha

Activate the Game Mod on the monitor or TV
