I'm using the Gonbes VGA converter and was wondering how frequently you need to use the rgb pots when going through vga with an lcd monitor. The way I'm building my test box they wouldn't be easily accessible.
 
Personally, never. Most of the boards I have used with my converter are pretty well balanced from the start.

I almost have to wonder if the pots are there to match the A/D's they use on those boards, not so much for adjustments related to the source video signal. Certainly it could be used for both.
 
I'm having this same issue building a test rig in a case. I've never had to adjust the RGB pots, but I do need access to the menu buttons frequently. I'm considering removing them from the converter board and mounting remote buttons in the panel.

Why not turn the pots up full and then solder wires from them to some additional pots mounted on your test machine's case?
 
Noob question: when soldering one pot to another do they have to be the same ohm resistance?
 
Going that far, wouldnt it be better to just remove those pot's, and run wires to mount them wherever youd like, rather than add in a new pot and trying to match it up? Essentially what you are describing is the same as removing the mounted pot by jumpering it to always send the full voltage across, then add a second pot after it.
 
Could do that too, but the pots on the pcb are so tiny I'd want to replace them anyway, plus I just got this thing and don't really want to hack it up :)

Wheres your sense of adventure? :-D I agree with replacing them with metal bodied larger pots designed to be panel mounted or something, as the little plastic guys wouldnt hold up to long. Id probably still just remove the old ones, ohm the range, and wire in a direct swap.
