My R9 270 is 7 years old. My HP monitor does not receive a signal and goes blank.
However if I repeatedly turn on and then turn off the entire system, the monitor will eventually
receive a signal and works fine... until the next time I turn on the computer.
I have:
1. Updated drivers
2. Have replaced HDMI
3. Tried a DVI cable
4. Unplugged HP computer and pushed the on button
for 20 + seconds to eliminate static.
Does this sould like a bad graphics card?
