Main monitor causing black screen on both my main monitor and secondary monitor

[G-MoneyAF]

As the title says, my main monitor is connected via hdmi and the secondary via DVI. Have been using both monitors for years, was working fine up until a few days ago. Computer would boot but neither neither screen came on, waited until my system auto logged on and tried windows + p to cycle monitors, ctrl + windows + shift + b, switching hdmi cables, disconnecting everything but the monitors, booting in safe mode, nothing worked. Desperately tried just having the secondary monitor plugged in and it works fine. So it seems that the main monitor is somehow the issue.


I can use the main monitor with other devices, using the same port, with no issues.


Any ideas on whats going on here?
