Question MSI Radeon R9 390 OC 8GB GDDR5 512-bit

Wait. So you were able to boot into window without video signal?

Did you try connecting the monitor to GPU card output? Or did you switch it back to motherboard output afterward.

Sorry, I must double check this when its not clarified.

I have integrated graphics too, that's why.
