very easy--cut your monitor cable--identify your pins (based on ultimarcs pinout) and hard wire to the monitor chassis --red signal to red signal, blue to blue etc. (these are color signals not the color of the wire--just so there's no confusion) I went from the arcadevga to a K7191 with no video amplification and the picture is just fine.
to identify which wire to which pin, use a multimeter and set it to the lowest ohms reading. when the needle zips or the numbers go to zero you know the pin you touched with one probe matches the wire you touched with the other--should take you about 15mins--and make sure you write it down.
