Well, I am getting itchy again. What can I do to this project while I wait for the new year.
I've decided that I also need to run 12V from the computer PSU, and use it to power the VGA. I do notice a little noise on the VGA as it is powered direct from the vehicle. And maybe this will also make the display a little crisper (if not by much). This is the 12V plug you see above in the storage bin.
Since I have made the previous power run using CAT5E cable, I have spare conductors for this job. The current 12V plug will remain intact. I will dig out a proper sized coaxial plug from my parts bin, attach to one end of the CAT5 cable and connect the other end at the PSU. This will leave me the existing cord for the future should I need to change out the display.
This won't take too long but should help take the itch off for a little longer.
To be continued, eventually......
