Hello. I just built my first PC last night and the monitor kept showing "no signal" until I removed one of my RAMs. After that, the HDMI cable I had worked but the display cable still shows no signal. I am using a Westinghouse 27" monitor with an NVIDIA geforce rtx 2060 graphics card. What could be the issue here? I would prefer to use the display cable, so is the cable itself the issue or is it possible that the port on either end is not working?
