Title: Help with Horizontal size...
Post by: lokki on December 02, 2003, 09:16:05 pm

Hi,
I have a 25 " RCA monitor with a sharper image board. (old monitor 13 yrs+) In my cabinet using ArcadeVGA.
The horizontal image size is too big. Even centered portions of the image are off screen to the sides.
I have played with the Pots. But there is no Horizontal size pot.
I can find. H hold, H pos, V hold, V pos, Brightness etc... But no Horizontal size.

Anyone can help?

Thanks

On most commercial arcade monitors the Horiz size (a.k.a. "Width") is generally a coil not a pot. The width coil may even be marked Horizontal Size. Coils are adjusted with a plastic hex tool such as one of Radio Shaft's # 64-2230, 64-2220, or 64-2223. Never adjust a coil with any kind of metal tool----it must be plastic.

Bob Roberts has a page devoted to width coil adjustment.
