Is a video voltage problem ??

[MrPoPo]

Hi !!

I'm testing to put a Dreamcast in my arcade machine and I have one question about de video signal.
I'm using a hacked VGA Box to send the video signal from the DC to the Arcade Monitor.I don't know why but the image is very bright and I have to adjust the monitor controls to see it fine.
I think it's a problem of the video output voltage ().

Can I adjust the DC video signal to equal it with the PC video signal ?
I don't want to adjust everytime the image.

THNX.

If you have a spare potentiometer lying around, you could try putting it in the video wire coming from the DC.  That might dim the image without adding any distortion.  (but it might not...)   You could play with turning the knob to see if a certain position works, and then measure the resistance and use a resistor instead.  Can't hurt to try, it can't blow anything out that way.
