My screen has been making horizontal flickering lines since a long time ago. I placed the blame on the graphics card at the time but since then I bought another one and same issue... This occurs no matter what I connect to it. PS3 using HDMI, PC using VGA... Same bullcrap. Also, I lose signal at random using YPbPr. I thought it was just that my screen was crappy, but I have noticed that the problem mostly occurs at night when there's lot devices on at the same time. Now, my room seems to have bad electricity where it kinda goes up and down and I get spikes. However, I do not know if this is actually the problem. I tested this in the living room and the problem seems to have disappeared, so I can only guess that something is screwing up with my screen.

Any help?

I'm leaving this video here. Forgive the audio, I was listening to a top 10 underrated creepypastas.
