You're not doing anything wrong, apart from using that monitor. The problem is not with your gun..... It's a problem with the monitor. I'm afraid that it's a problem that you won't be able to solve.

That's not a monitor for gun games that flash the screen. It's simply not designed to cope with that. The problem lies with the voltage regulation on that design. That's why, every time the screen flashes the image zooms slightly then returns to original size. All monitors do it a little bit, but those particular monitors are not able to cope with very rapid high intensity screen brightness changes.

I've seen this problem several times.

Sorry!! But your only solution is to use another monitor.

Or alternatively :

Buy some LCD Top Gun's.    ;)

JKD The Lad:
thanks for the help, but seriously?
I have to return the guns?
this along with my fake dragons layer cd and defective arcade vga means I'm going to have to do a lot of shipping!

that cant be right! I read on retro blast : http://retroblast.arcadecontrols.com/reviews/betson2.html
that the act labs light gun works perfectly with the monitor!
Are you sure that I have to return it?

The retroblast review says "The area where the Betson monitor seemed the weakest was in screen regulation, which is a measure of how well the monitor holds a picture "steady" while large changes occur in the displayed image."

That monitor will simply not cope with the screen flashing that occurs when your act labs guns fire. We have two of these in the arcade, or at least we did until this poor regulation caused too many problems with them. There simply is no way to fix that zooming problem that you described. It's all down to cheap design and low grade components. That's why the Betson monitors are cheap to purchase in the first place.

They're great as a general arcade use monitor, but absolutely useless on gun games that use screen flashing, like most of the earlier Namco shooters. That's how I discovered this problem. So basically, if you want to keep that monitor, then you need to invest in an LCD Topgun instead of the Act Labs one.

Sorry that I can't give you better news than that. It's just not possible to fix that problem. So you need to choose to change the monitor or change the gun.

Kortek generally produce reasonable monitors, but my experience of the Betson badged ones is that they're a real duff design. We still have them on Fast & Furious and they really do suffer badly from instability and also suffer from colour purity problems.

JKD The Lad:
alright, I guess I do.
Thanks for the info. I'll make sure to call act labs in the morning
