Title: Guncon 2 on computer monitor
Post by: phatoni on June 29, 2005, 05:47:46 AM
Hey I think I found some disscussion about this a while ago on this forum but frankly I didn't really understand much of it. Anyway I have my ps2 hooked up to my computer monitor through a universal VGA adapter. I was wondering if I had a game like Time Crisis 3, would the Guncon 2 light gun work on my monitor?

Universal VGA adapters upscan a standard video signal. This looks like crap. You are better off playing it on a tv with s-video or component video.

the problem is I don't have a TV. Right now I'm in college and I don't have a TV in my room and probably won't be getting one soon.

Upscanned via composite, s-video or RGB, your guncon won't work on your VGA monitor. These guns rely on very specific timing with your TV, and with the different, higher, and variable rates of sync that a computer monitor uses all bets are off. If the gun isn't made to support it, you can't count on it working.

All lightguns work on knowing exactly where the electron beam scanning the screen is. In the case of the Guncons, they do this by monitoring the composite signal, and extracting the horizontal and vertical syncs.

As soon as you upscan the signal, those horizontal and vertical sync signals on the composite don't match what the electron beam is doing. Result? One confused gun.

The same goes for things like high scan rate TVs (100/120Hz upscan), and LCD/Plasma/Projectors which just plain don't so the scan stuff.
