Title: Makvision M3129DF-TS picture off screen at 31khz.
Post by: Supersonick on September 21, 2014, 04:45:12 pm

Hello,
I have some problem with arcade monitor Makvision M3129DF-TS . I am using Grovymame, and the problem I have is with 31khz games like Wargods, NFL Blitz etc.. when monitor switch to 31khz the image is not centered, half of it is out of the monitor (to the left) and the rest of the monitor is showing black/grey area..I verify this is hardware issue, as XP boot logo is off centered as well.
Is there some way to have the monitor centered automatically when switch to 31khz? Or do I have to play with potentiometer every time?
Thanks for your comments!
Regards.

there is a small daughter board just behind the flyback,this has a 31khz horizontal hold pot-it may just need a minor adjustment
