Can't find my second monitor, help?

BunnyB · Sep 12, 2013

Hello, I am unable to find my secondary monitor for some reason. I have tried HDMI, DVI and VGA, I connected them on my motherboard and my graphic cards and nothing worked, same results everytime. Also, i checked task manager and i couldn't see it there either.

My second monitor are ASUS VS239H-P.
My main monitor are BENQ XL2420T and i used DVI for that one.
My graphic card are GTX 780.
And my OS is win8

Also, you might want to know that my first PSU kept short circuit the power whenever it even touched the outlet, i got a new one now and everything seems fine so i dont know if it made a different.

Update: I just connected the cable from my main monitor into the secondary monitor and it works instantly.

Have you tried going to display properties? Right click on your blank desktop> personalize> display settings. Can you set it up there?

Yes, there's nothing there but my main monitor.

Hm. So we know both monitors work individually. Have you tried every port on the graphics card to a single monitor? It sounds like we only know for sure that the dvi is working.

I have tried every port on the graphics card, i tried one VGA cable, one HDMI and two DVI, one DVI-D dual lin which is the one im using for my main and the other is DVI single link. I tried the HDMI on both of the ports i found behind the computer, on the graphic card and motherboard, i tried the DVI aswell on the graphic card and on the motherboard. The graphic card doesn't have a VGA so i only tried that on the motherboard.

I'm sorry, i missunderstod what you said at first, I just tried single HDMI on only the main and it didn't work and i tried the second DVI and it didnt work either until i moved it up one step.

I found out, sorry for busying your time. ^^ I installed a older version of the NVIDA driver program and it works noww.

Ok now we're getitng somewhere. Only one dvi port seems to work on the gpu. All I can think is the gpu is faulty. This should be as simple as plugging in the monitors and going to display settings. I don't know of any settings to turn ports on/off. You might want to start an RMA for the card.
