    Simple questions. Does anyone have an online guide to making up long VGA cables with CAT cables(Searched forums but still confused if honest) or is there anyone out there that wants to make some pennies by making on up for me?

    How long is your required "long VGA cable" ?
    VGA (a form of RGB) doesn't travel well over long distances. This is especially so at higher resolutions (say 1024x768 upwards). In my job (as field apps engineer for an IC manufacturer) we have some customers piping VGA over hundreds of metres (KVM or Keyboard/Video/Mouse distribution systems) in financial dealing rooms & similar. They have to use active devices (usually our ICs :) to precompensate & decompensate for both imbalances between the R,G & B channels and for losses at higher frequencies. They usually use differential amplifiers/drivers on each RGB video line with a differential to-single-ended "receiver amplifier" at the far end. But they do indeed use CAT5 or CAT6 cable.
    So your results will vary according to your mileage (or more likely yardage in the home-user case).
