So I just built my first computer and when I try to go install windows on it the tv im using (instead of a monitor) isn't picking up any signal. I have checked everything I know that could be the problem like the tv's hdmi port not wotking, the computer not being on and the hdmi cable being faulty. And nothing has worked I've put the cable into the motherboards hdmi port and the gpu's hdmi port and yet again nothing has worked. What can I do or what is the problem.
