I have recently built a PC and it won't recognize my monitor.
The computer seems to run fine since all fans are working but it just won't recognize my monitor. However, when i plug the cable to my computer and plug it out the monitor button changes color but when i plug it back in, the monitor says "monitor going to sleep". I tried connecting the monitor to my laptop and the monitor seems to be working fine. I just don't know what the problem is. Please help me

Make sure you've pluged it on the GPU DVI port and not your motherboard DVI port.

I figured out the problem kinda
my monitor(old hp monitor) turns on if I take out my graphics card but if I add the graphics card and plug in the PCI cable to it. The monitor does not respond. What do i do?

either look like driver issue or a defected card.

Contact the GPU company and ask for supports if you think you have the proper driver installed.

Another thing is when I installed the microsoft windows 7 on my newly built computer I did not have the graphics card in there because of the monitor problem but the other thing is my monitor is old and doesn't have the cable to connect to the graphics card(just the blue vga cable). Can that be the problem?

I currently use the VGA to DVI adaptor on one of my monitor and it never caused any problem.

When you go on device manager do you see your card ?

windows start button / control panel / hardware and sound / Device manager: then you should display adapter and it should show your GPU if you click on it.

ahh the thing is when i tried using hdmi cable directly to my graphics card i was able to see my screen. I think it's because I don't have an adapter haha... right?
