Ok, if you have not done the video amplifier mod yet you have to do it as it is a 100% improvement in screen brightness and color depth. The mod is listing on page 14 of this thread and their is a video that explains how to install it. I would like to simplify the process, though.
First, you need to see if your video card is putting out 5 volts on the #9 pin on the serial cable. The easiest way to verify is to unplug the original serial cable on the computer above the monitor. Plug in the serial cable provided in the video amp kit into the computer. Put your multimeter probe on pin #9 of the other end of the cable and other lead of meter to ground. Turn on the machine. If you have 5 volts you are good to go. If not, you need to bring power and ground from your computer as in the video.
Next, instead of fabricating another cable, simply cut off the original cable about 19" from the monitor end and simply strip the wires for R/G/B/Ground/SV/SH and attach to the amp. Use the new cable to go from the amp to the computer and you are done.
You will need to shave the bottom of the cable connector at the amp end since it is too big and puts strain on the board if not shaved down.
I mounted my amp on the bottom instead of side cabinet so there was no strain on the connections and it is easier to inspect.
The difference in picture quality is amazing.
