Here's my setup: 2 Monitors, one 144hz and one is a older 60hz. 144hz one is connected by DVI-D and the older one is connected by HDMI with two DVI adapters on both ends. Including these two i have a Sony television connected by HDMI. Both are Benq monitors. Worked flawlessly until now.

CPU:Intel i5 2500k
GPU XFX AMD Radeon r9 390
Mobo: Semi old ASRock z68 pro3
OS: Windows 10

Here's the problem: I woke up in the morning, started the computers, and both of my monitors say "no signal". I reckon that something must've busted up, but then i notice my keyboard LED showing normal windows stuff so that must mean it booted normally. I then go check my TV and bizarrely the computer shows normally there. When i go into my display properties there's nothing there, computer won't detect them at all.

First thing i thought that the cables or the ports have somehow broken so i take one of the DVI adapters and put it between the computer and the television and it works so ports are not broken. Then i take the HDMI cable that works succesfully with my tv and i plug in my Monitor with it... doesn't work, no signal.

Now i'm thinking, did both monitors break during the night? So i test the older monitor with my old Laptop and plug it in with a VGA and it works so the monitor doesn't seem broken. Then i test the newer monitor by plugging it in with HDMI to one of my TV boxes and it works as well so the monitors work. To recap, the newer monitor works with HDMI with a TV cable box but doesn't work with HDMI on my computer.

Since i have access to my computer with the television and a cordless mouse i start thinking it's a software issue and here's what i've done thus far with NO success:
Reinstall Windows 10
Uninstall AMD drivers
Update AMD Drivers
Try older AMD Drivers
Clear CMOS
Take out the GPU and reseat it

None of these worked, still a connection only to my Television. How can a computer suddenly just reject 2 seemingly fine specific monitors? Now i'm travelling to my brother over the weekend to test the monitor with another computer and my computer with another monitor. For now i'm thinking it's a GPU problem and i'm very close to just RMA it. This is such a bizarre problem.

TL;DR: 2 Monitors suddenly get No signal, Television still works. Cables and monitors seem not broken.
