2 monitor setup

February 28, 2011 at 08:05:38
Specs: Windows Vista
I just got a second monitor and am trying to connect it to my PC, which has a video card with both VGA and DVI out. I had 2 VGA cables already, so I bought a DVI->VGA connector. When I plugged the second monitor into the VGA port the computer instantly recognized the second monitor but no picture shows up on the new monitor. I can go into my display settings and change the primary monitor and such, but still can't get a picture on the DVI screen. I have troubleshot by switching the monitors, in which case the monitor on the VGA always works and the DVI does not.

Anyone know what else I can try?

I also have a video card with VGA and DVI. In the past, I had two VGA moinitors and I had no issue with the setup.

When you're in the display settings, you should see both monitors in the upper section of that window. Right-Click on the second monitor and then Clode or Extend desktop and press OK. See what happends.

If that doesn't work, i'd make sure you have the latest drivers for your video card. Also, try plugging the second monitor where your primary monitor is and make sure it works.


Let us know.

Thanks for the reply Night,

I have already tried switching the monitors to no avail: the monitor that is plugged into the VGA socket on the Video card always works. I have opened up the display and my computer thinks the monitor is there. I can extend the desktop and even use the 2nd monitor as my main, which then pushes the start menu off of my VGA monitor onto the DVI that isnt working.

The video card drivers is one thing I have not looked at. I will confirm they are upto date tonight and let y'all know what I find out.

I'm starting to think the DVI port isn't working.

You're using a DVI to VGA converter right? This shouldn't be a problem but..maybe it's the port. It shouldn't be this difficult to get dual monitor.

Yes, I have a DVI to VGA converter. The most confusing thing about the whole this is that the computer is recognizing the monitor by its manufacturer and model.

I'm baffled. I don't know what else to recommend. If it were me, i'd buy another video card, slap it in and see if it works. If it still doesn't, return the video card.

Check the pins at every end. Get a flashlight and look at the DVI output from the video card. Make sure there's nothing missing or there isn't a pin stuck somewhere.

My "solutions" are getting poor. I should stop.

The term CARD is frequently mis-used.
If the video adapter, or any device adapter, is built into the mboard and cannot be removed, IT'S NOT A CARD !

If your onboard (built into the mboard) video has both a VGA port and a DVI port, when I was looking at mboards about two years ago, I found that some mboards have a different type of DVI port, and that type WILL NOT work with a DVI (male - pins) to VGA (female - pin holes) gender adapter, or a DVI to VGA adapter video cable, to make a VGA connected monitor display !
If you have a generic system, if that applies, there is probably info about that in the manual for the mboard.

There is no such thing as a VGA (male - pins) to DVI (female - pin holes) gender adapter, or a VGA to DVI adapter cable, that will convert a VGA port on a video adapter to work with a DVI connected monitor - there are not enough connections in the VGA port for that to work.

In any case, Windows only enables one display by default (at least, that applies in XP and below).
RIGHT click on a blank part of your main desktop screen, select Personalize, then Display Settings.
Hold your cursor over the two displays, one at a time.
One will display Not Active.
RIGHT click on that display, and select Attached.
Click OK at the bottom of the Display Settings window. Close the Personalization window.

Windows will retain the second display as long as it is still connected while Windows is running, even after you Shut Down Windows.
