Monitor Not Working When GPU Is Plugged In To Motherboard?

John Sawyer · Dec 30, 2014

I recently had to buy a new GPU because the old one just would not work. the current one when plugged in to the motherboard doesn't work regardless of if the monitor plugged into the GPU or the motherboard.

We need a bit more information. What are the system specs? What exactly do you mean by "not working"?

shortstuff_mt :

By not working I mean the monitor doesn't detect anything is plugged into it. Specs are: http://pcpartpicker.com/p/pL9Y8d.

Remove the gfx card and see if the integrated works then.

Which GPU was originally in the computer? The component list shows a GTX 660. Is that the one you have now? Did this system ever work? If not, we have a troubleshooting checklist in the stickies for this type of problem. There's also a link to the checklist in my signature.

Also I should note that I have an old junky monitor because new ones are expensive and it is plugged in via an adapter that converts D Sub to HDMI. d Sub is in my monitor, HDMI is in my GPU. however for the motherboard I don't need the adapter because the motherboard has no HDMI input so I use d sub for the motherboard.

Unless it is a converter and not an adapter, you can't get analog (VGA) from the HDMI (digital) port on the PC or the card. Does your gxf card have a DVI-I port?? If so, use that with a DVI-I to VGA adapter.

Integrated works with out GPU but it's not super helpful since the computer won't be as powerful.

Yes the gtx 660 is the one I am using now. The old one was this:

It did not work. I checked the check list and everything looked fine.

Didn't you see my post? Are you using a converter or an adapter to go from HDMI to VGA?

John Sawyer · Dec 30, 2014

clutchc :

I'll try this but I need to buy an adapter. Even so, wouldn't the motherboards graphics still work? They don't require an adapter and they worked when the last graphics card was in.

John Sawyer :

OK, that is actually a converter. It has the electronics to convert a digital signal to analog... or so they claim. But I don't see how it can work. It has no power source. HDMI carries no analog signal like DVI-I.

Try one of these with the DVI-I port on the card.: http://www.amazon.com/StarTech-DVI-Cable-Adapter-DVIVGAMF/dp/B000067SOH/ref=sr_1_2?s=electronics&ie=UTF8&qid=1419973661&sr=1-2&keywords=dvi-i+to+vga+adapter

Does the integrated video have a VGA port?

John Sawyer · Dec 30, 2014

clutchc :

Yes the integrated video has a vga port. Question. are there
Dvi d to vga ports? because the GPU has a dvi d port and with the way my case is it is easier to put it in dvi d instead of dvi i. if not I can make it work but it would be nice.

DVI-D is pure digital. It carries no analog signal. Only the DVI-I carries both analog (VGA) and digital. If you look at the DVI-I port, you will see 4 holes surrounding the flat slot that sits to one side. Those 4 holes are the analog signals. The DVI-D port will have those missing. That's why you have to use the DVI=I port with the adapter I mentioned above.

Try this; If you remove the gfx card* and use the integrated VGA port, the old monitor should produce a display. If it does not, there is another problem.

* some boards won't enable the integrated if they see acard in the PCIe x16 slot.

Ok thanks so much! Looked around and figured out that my monitor has a DVI-D port, and the GPU has a DVI-D port. Got a cable and connected them and it worked! I appreciate the help!

You should get a brighter, sharper display with digital than VGA.
