    I need to make a short VGA extension cable for a PC, mainly due to the
    custom case having a bar near where the video card plug is.

    I found the pinout here
    I take it I only need 8 cables to connect between the male and female ends
    to get the monitor working? Also do the ground pins (5, 6, 7, 8 & 10) just
    get connected together?

    You can buy one for peanuts.

    See DSE, WES etc.

    Pins 6,7,8 are the RGB ground returns. They shouldn't be lumped
    together. A good quality extension cable will have 75 ohm coax for
    each of the RGB signals. If you use ordinary wire, as is the case with
    a cheap cable that I have, you may see ghosting at high resolutions. I
    have made my own quality extension cables, for use with a KVM box, by
    re-terminating VGA leads from scrapped monitors.

    I need one that has a small plug on it, as in the old ribben cable that was
    used years ago for serial cables.
    Basicly the cable only needs to be at least 50mm long because of the space
    limitations and a lage plug won't fit in the space.
  5. At 50mm you can use esentially any wire. Find a solder tail HD15 male
    and female connecter and just solder the needed wires pin to pin.

    I ended up doing that, and it works fine. In fact it is the monitor I'm
    using right now.
    Thanks for the help

    I had problems with my old 20" sony monitor shadowing and not being crisp.
    Was a monitor extension cable at fault. Tried 3 different ones, 2 were from
    a different manufacturer and it still shadowed.
    I nearly threw the monitor out!

  8. 50mm is not a long cable.
