I need your help. I have purchased a new asus tuf rtx 4090 and installed it replacing my 2080 ti. I have triple 1440p monitors. After swapping the cards the 2 outer screen are flashing. I have done a clean install of windows 10 to see if it was a windows issue but still it flashes. Everything was working fine on the 2080 ti in before. Any ideas?

Ok, update. In windows the 2 outer monitors were set to 74.925 Hz because they are 75Hz monitors. Switching them to 59.951Hz seemed to have fixed the issue. Any idea on how or why this is happening. And any ideas on how to get my outer monitors to run at the 75Hz they are capable of?
