I've set up my PC but the monitor shows 'no signal' and the mono debug light is red. What do I need to do to get a display?

To get a display, you have to connect the monitor to the motherboard directly. But make sure your CPU has integrated graphics; if not, you won't get any video output just like you’re seeing now.

Could you share your full specs? It’ll help in figuring out what might be wrong. What CPU and motherboard are you using?

Check the lights on your motherboard, especially near the red light. If it says 'CPU' or 'RAM', there might be a problem with either the CPU or RAM seating. Make sure everything is connected properly.

You'll need a GPU if your CPU doesn't have integrated graphics. Without a dedicated GPU, there's no way to get a video signal.
