Hi,
I have a PC with Windows 10 installed. It has a Radeon RX 580. The HDMI output is connected to a received which is connected to a TV. I know that my cable, receiver and TV are working because if I use this very setup with an Xbox One then it works fine, but if I connect that same cable to the PC instead, there's no signal. The PC seems to boot fine (no abnormal beeps).
Do I need to first connect the PC to a monitor via HDMI and setup the GPU to output via HDMI? The PC is otherwise setup with the driver already.
Thanks.
