Hi,

Usually the values are 1Kohm for RGB lines and 5Kohms for sync line.

Well you can use 470 Ohms like Xian Xi said, but I think they are not common

Un saludo

I can order the 500ohm with 0,25 watt.

How much watt should i use for the sync line? And is 5000ohm not a bit much?

Typically you should not need a pot for sync, just R G and B

I know but my sync i also messed up. It has a small glitch. I do think i need a 1k resistor in the line, but im not sure.

Just out of curiosity, why not just stick resistors on the lines? Do you foresee the need for on-the-fly adjustment beyond the brightness and contrast knobs on your TV/monitor?

I just use 220 ohm resistors, one each on R G B and Sync. a 500 ohm pot for R G and B should be fine, and find a suitable resistor for sync if needed.
