Hantarex Polo Star 28 with Pandora 5S

[uha666]

Hi,

I recently aquired a arcade machine with a 28" Polo Star setup.

I hooked up a pandora 5S, to it, using the vga connector, but i only displays half image.
Initially i thought it would be a frequency issue since i saw some users stating the for the VGA mode a SVGA polo star was needed since.

But after switching back to the RGB connector the image is still the same.

I attached a picture of the issue.

I already tried ajusting the POTS but the horizontal ones have no effect.

Any help would be appreciated.

Regards
