Input Signal Not Found, Check Video Cable and Video Source

[DarkComputer92]

I keep on getting "Input signal not found, check video cable and video source," whenever I connect my monitor to the computer that I built. What do I need to do to fix this problem? Is there a problem with the PC I made?

Does it have a working HDMI port ? I can't see you product therefore I can't say more.

Yes, the computer has a working HDMI Port. I am using a HDMI cable and connecting to a EVGA GeForce RTX 3060

Now I can see more light. You machine has at least 2 HDMI ports, 1 from motherboard and 1 or more from the EVGA GeForce RTX 3060 card BUT all video out ports of the motherboard should be disabled automatically due to you installed a video card.

Does the monitor work with another computer ? If yes, that means your build is not complete.

@DarkComputer92 -- is this your monitor: HP 24mh 23.8-inch Display Product Specifications | HP® Customer Support

It lists: 1 DisplayPort™ 1.2 (with HDCP support); 1 HDMI 1.4 (with HDCP support); 1 VGA

So, have you configured the monitor to "listen" to the correct source?

Getting a "no signal" message implies that the monitor is "listening" to an inactive video-source.
