Hello, I just replaced the new GPU (same chip, other manufacturer). Everything was running fine, but when the secondary monitor was plugged in, it started to make red spots on primary monitor. All cables checked.

 

Primary monitor BenQ XL2411 (144Hz) Dual DVI -> GPU port DVI
Secondary monitor BenQ GW2270 DVI (60Hz) -> GPU port HDMI
GPU MSI GTX 1080Ti Gaming X
Windows 10 Pro 64-bit.


Thanks for help!

Do they still display correctly when only 1 is plugged in?

Ive witness monitors in the past, when a new and old monitor are placed next to each other that an electromagnetic thing happens and damages the new screen.

Yes they do. Now i have only plugged BenQ XL2411 (144Hz) Dual DVI and work fine. Yesterday i had EVGA 1080Ti SC2 ICX and two monitors works fine. Maybe the bug is in GPU?

My mistake, i found it BenQ XL2411 work only 1920x1080@60Hz. When i change to 1920x1080@144Hz so its not working.

EDIT: I have a cable support 144Hz, DVI-DL. I dont know why is it hapenning.

You sure it's a Dual Link Cable? Any reason you can't go HDMI between the card and the 144hz display?

HDMI doesn't support 144Hz.

HDMI 2.0 does? Which the 1080 Ti has?

Does it? I might have been thinking of 1.4...

Oh the monitor only supports HDMI 1.4 anyway, so ignore me... Has to be DVI-DL.

Yeah it's DVI-DL, I'm sure of that. Bcs, yesterday it worked fine with EVGA 1080Ti, today I exchanged for a MSI 1080Ti Gaming X and not working, drivers reinstalled.
