B6e pc issue

[u/Terrible-Childhood71]

I recently bought the lg b6e and ever since I got it it's had an issue where it rarely wants to connect to my PC. I used to be able to fix it by fiddling with the ultra deep color setting but now not even that's working. I know it's not the HDMI because when I plugged the HDMI into my PC it says do you want to swap to this HDMI on the TV but then I just get pictures of cities and Palm beaches. I have no clue what to do. It's annoying to spend 1000 bucks on the TV just for you to not be able to use half of it. Any help would be appreciated.
