    Default Second monitor wont recieve a signal from Laptop

    I am using an XPS L702x laptop for school and am doing a lot with Excel and other programs that I need to be able to read all of them at one time but I have been noticing that it has been taking me more and more time to just switch between windows and stuff so I grabbed an old monitor we had around the house and bought an HDMI to DVI-D cable to connect it to my laptop.

    When connected and both are turned on it shows "no signal" and when I disable the Intel HD 3000 graphics adapter it switches over to the monitor. I have checked the monitor on a second laptop (XPS 14 with an nvidia 8400 in it) and it worked fine with that, it both duplicated and extended the desktop without a problem.

    My primary laptop is an XPS L702x with an Nvidia 555m GT which should easily be capable to run the main screen and a second monitor, however, it refuses to "detect" the second monitor without me disabling the main display. The monitor I am trying to connect to is an ACER p191w which isn't the new thing in the world, but it was laying around the house not beign used. I don't really want to buy a second display since I don't have the fund and because I think its less of a hardware issue and more of a setting issue. I am using windows 7 as well.

    I have tried everything except a full reinstall of the OS (which is out of the question until Thanksgiving break). I have reinstalled both graphics drivers and I have tried downgrading the graphics drivers.

    The last thing I could possibly think is that a windows update messed up some weird setting somewhere but maybe someone here has had a similar issue so I thought I would make a quick post asking for suggestions if anyone had one.

    E: Forgot to mention, plugging my laptop into my tv (HDMI to HDMI) works fine. I can easily duplicate or extend the display. I dont think there is an issue with the wire because I just checked it on another Laptop (my moms Gateway thing) and it worked fine on there as well.

    Well, sorry for the double post but it seems perhaps my graphics card may be going bad in my laptop.

    This morning when I turned it on in class it came up to the desktop and was very pixelated and very weird colors, I couldnt read any text on the screen or actually see the desktop, however I could see the mouse cursor moving around. Hopefully my laptop makes it to christmas break so I can send it back to have it repaired or something. I still have a little under 1.5 years of warranty on it thankfully!
