Hi,
I recently ugraded from a rtx 2070 to a brand new sapphire pulse 7800 xt. My setup features a main screen (144hz display port) for games and a secondary one (100hz with hdmi) for watching videos/spotify/discord while gaming. Since I replaced the GPU I got some visual glitches on my secondary screen (green flickering), and I'm just tired troubleshooting all day and trying new solutions.
Things I did:
DDU several times
Tried to turn on/off Freesync on the second screen (1st one is not compatible)
Disable MPO
Underclock the card
Disable hardware acceleration on browser
None of these worked. I found a temporal workaround that consist on setting my secondary screen as my primary, but I really need those extra hz on my primary one.
