I have an hp pc and a dell monitor. They connect with a dvi-d cable. Old stuff, I know, but up until three days ago it worked fine. I accidentally unplugged it and ever since then the monitor won’t come out of power saving mode. When I press the monitor buttons, it says it is not receiving any input from my computer. I’ve done every method of restarting the computer, taken out and cleaned the ram, also taken out and cleaned the graphics card, and replaced the motherboard battery with one which I know has a charge. The pc turns on fine, just the monitor apparently isn’t receiving a signal from it other than registering the connection. Also, the monitor and dvi-d cable are fine, they worked with a different device.

with the graphics card removed, does your motherboard and process support integrated graphics where you can plug the screen into the motherboard?

Yes, it has an option for the dvi-d cable to plug into the graphics card or the motherboard. I have tried both options and gotten power saving mode for both.

when plugging the monitor into the motherboard, the add-on graphics card needs to be removed AND the processor needs to support inbuilt graphics.

Thank you very much, I removed the graphics card and my computer now works. However, since I always had the dvi d cable plugged into my motherboard, does that mean I’ve always been using integrated graphics? If so, is there a way to make my graphics card work so I can use that? I appreciate your help this was huge!

if a PC detects an add-on graphics card, the onboard graphic ports are disabled.
so if you had a cable going from the monitor to the motherboard port, and another cable going from the monitor to the add-on card port, the PC would have used the card's port.

I have a vga cable and a dvi-d cable. If I plug the dvi-d cable into the card and the vga cable into my motherboard and then plug them both into my monitor would that work?
