LG 4k TV used as a monitor stopped working properly (and often even connecting) after major windows 10 update cca 2 months ago. I tried everything I could, updating and reinstalling drivers, connecting different monitors, I even reinstalled windows 10 (unfortunately I updated it again before trying 4k monitor first), nothing helped. When it connects, the displaying quality is horrible and no settings help. When I connect other monitors to PC, tv stopped displaying completely. Can anyone help please? Thank you

Connect LG 4k TV with another system and check if it works properly. If not, then visit the authorized service center.
Connection to both of my notebooks works without a problem, the issue is only with a desktop PC, which worked until this major windows update, and after PC restarted after update, all was destroyed. So the problem is not in PC (other monitors work ok) and in TV, but clearly in windows and its updates.
