PC Running but no signal to monitor

JNolan99 · Dec 30, 2013

Hey, I recently completed building my PC, however my problem is when I install the graphics card (Asus Geforce GTX 770 2GB) the monitor does not get any signal from the PC. However I don't think the graphics card is damaged as it has two green lights by the DVI-E ports on the top and the fans on the graphics card are going. I have managed to download Windows 7, go into Bios ect, it runs perfectly using onboard graphics.

Any help would be appreciated thanks.

Did you connect the power plugs to the card from the PSU?
Should be 1 x 6 pin and 1 x 8 pin.
Also switch the default graphics device in the bios if it didn't do it automatically

What connection do you actually use? (DVI, VGA, HDMI?) Did you connect it from the GPU or from the Motherboarboard port?

@jay2577 The power plugs are connected correctly or else the 2 green lights wouln't turn on, on the graphics card and i can't enter BIOS unless I unplug the graphics card and use onboard graphics

@ deswryn_21 I was using a DVI Port plugged into the motherboard as my graphics card doesn't have a port. I also have a HDMI cable which my graphics card does have a port but still no connection if I plug HDMI into graphics card or motherboard.

That's odd. You might have to connect directly to the GPU itself as it doesn't work for me if I use the ports in my motherboard. What monitor are you using exactly? If it has HDMI then use the HDMI.
GPU HDMI ---> Monitor HDMI.
Also if your monitor has a couple of input, you might as well change the input to what inpu you are using.
Example, you plug the HDMI in HDMI(port 1), then set your input to HMDI 1. Refer to your monitor manual.

Uhmmm. I was asking what monitor are you using. XD

LOGIK 24" LED TV L24FE13

Could it be that i'm using a TV not a monitor? and also the HDMI is working now using the onboard graphics

Yep. It's a LED TV so it's a TV. Well I use TV myself as my monitor.

Now, check the back of the TV if it has multiple HMDI. Connect the HDMI cable to HDMI 1 port (or any other port, just remember which) then connect the other end of the cable to your Graphics Card.

Just tried that, still no signal going into TV.

deswryn_21 · Dec 30, 2013

Did you set the TV to use the HDMI 1 port as the video input?

jay2577 · Dec 30, 2013

Is your TV full HD? Your graphics card might be giving the TV a higher resolution than it can handle
