I've got a Samung Vision Pro I just stuck in a Galaga. Its probably around 8 years old but only maybe has 10 or so hours powered on. Anyway, I connected everything up and the color looks great but... I'm getting two images on the screen.

Basically, instead of:

[.........]
[.........]
[.........]

I get:
[....][....]
[....][....]
[....][....]

The game comes up but you get two instead of one. You can play just fine but you have a left galaga and a right galaga, haha.

Anyone ever seen that?
 
Thanks for the help as I don't have much experience with monitors.

The NO SUCH was a bit out of line I'd say. You could have been at least nice about correcting me. Not everyone is a monitor genius. :(

The front of the Manual has Samsung....Vision Pro. I assumed it was a complete Samsung product as Happ does not exist on it anywhere that I saw.
 
did this monitor ever work right before? it's a Happ Vision Pro, they used Samsung tubes. one area to note is what model Vision Pro do you have? it sounds like you're trying to run a medium resolution monitor on standard resolution Galaga.

grab pictures of the big board on the monitor, particularly any labels you can find. I don't know anything about the Vision Pros, but I can tell you from a previous experience, we got a bunch of games from a place that closed and they had a Star Wars Episode 1 pinball, and because some knucklefuck had the power supply jumpered wrong to 137V, they burned out the original monitor, and said knucklefuck replaced it with a Vision Pro VGA monitor because it had a VGA plug on it, and I don't remember exactly what it looked like cause that was a long time ago, but we wound up throwing the correct CGA monitor in and hacking a computer monitor cable and adapting it to the right connector and it worked until we got rid of it a few months ago.

I still have the VGA monitor in my possession.
 
just in case you were wondering, I did a Sega NAOMI board swap, forgot to change the resolution dipswitch, and hooked to a standard res monitor and I got... double vision. VGA on standard res gives a double picture (whereas a medium res would be a triple picture)... so I'm going to lean on your monitor being VGA with you running a standard signal at it, just a guess.
 
There is a white button on the monitor not too far from where the video signal plugs in. Push it and see if it helps.

otherwise, try adjusting the vertical hold...

oh shit, I didn't even think about that, it's a vertical game. doh!

yeah, sounds like your V-pos or V-hold is wrong. I would also be inclined to say verify that the sync is hooked to the right spot, I wanna say this Pac-Man with a K7200 I worked on had some stuff that wouldn't adjust out right cause I had it on the wrong sync pin. not sure if that'll make a difference.
