Idea for using a Desktop GPU on a Laptop to Drive Internal LCD

  1. Mar 7, 2010 #1
    There are a couple of products on the market which allow you to attach an external desktop gpu to the laptop and then use an external monitor and play games using the the desktop gpu instead of the weaker gpu in the laptop.

    It's a great idea but it means that you must carry an external monitor with you if you plan on playing games where there isn's another monitor.

    So I just want to ask if it is actually possible to use a desktop gpu to play games on the laptop's build in LCD.

    A couple of guys have come up with the first part and I came up with the second part
    1st part:

    1/ Cut a cheap MXM card - just want it as a solderable blank to shove into the mxm slot.

    2/ Attach ribbon cable on MXM blank and to a PCI-E riser to appropriate pins.

    3/ Attach external 12V to tap onto the 12V line of pci-e riser.

    2nd part:

    1. you do the above (desktop gpu now plugs into mxm slot)
    2. build/buy something http://go.notebookreview.com/?id=525X832&url=http%3A%2F%2Fwww.montest.com%2Fmontest-tl.html" [Broken]?

    so now you have your input through the mxm and your output through the desktop gpu DVI to the LCD LVDS
    What do you guys think?

    I was also wondering if you could use a laptop with switchable graphics to simplify the process (http://go.notebookreview.com/?id=525X832&url=http%3A%2F%2Fgizmodo.com%2F5467206%2Fnvidia-optimus-switches-seamlessly-between-amped-up-and-power%2Bsipping-graphics" [Broken]?)

    Something like this would be immensely helpful for a lot of people and for me personally as you wouldn't have to upgrade to another laptop when the gpu becomes out of date.
    This would also be a great combo for the sager laptop with the 6-core gulftown processor.

    Any ideas will be appreciated
