My monitor works fine when i turn it on without changing display, but when i switch display from TV to monitor it flickers non stop and never stabilizes. I just got a new GPU the 4090, i have a LG CX. The TV doesn't flicker at all its just the computer monitor, never had the problem on my old 3090 GPU. All the settings are correct in display settings as far as i can tell and i have reinstalled drivers but nothing works. Any advice? The HDMI cable and GPU are brand new.
