So i have a MSI Optix G27C after i used hdmi passthrough on xbox one it stopped posting on any pc when using hdmi. when i try to use hdmi with my pc it sais "No Signal" but using same hdmi cable on xbox one or xbox 360 it post no problem. on a 2nd monitor again using the same hdmi cable it will post.
Tried resetting monitor, Tried different gpu drivers, tried intel hd gfx (used to work when i got it), GTX970m, Rx470,Rx580,GTX 1070, Rx5700XT none of them will post, turning it off and on again, different hdmi cables.
