Standard resolution game on Medium resolution Monitor?

[BLACK KNIGHT]

I thot that you couldn't run a standard resolution game on a medium resolution monitor, but my friend has a medium resolution monitor and plugged in a standard resolution game and it looked fine.  Is there a downside to doing this?

monitor must have an auto switching. Whats the monitor? Whats the game ?

Some arcade monitors (such as the Nanaos that were included with some later Sega games) are capable of dual-resolution via a switch.  Additionally, others such as the Wells Gardner D9200 autoswitch.

If your monitor is not switchable, it is possible to convert standard-res to medium res using an upscan converter that can take a 15Khz signal and upscan it to 25Khz.

Oh, interesting.  I don't know what kind of monitor he has but the game is War: Final Assault.  It's a 1999 game that is a first person shooter.  According to KLOV it has a medium res. monitor and it certainly looks like it when you look at the game.  So I was extremely surprised when he plugged in Soul Edge and the picture looked fine.

I guess getting an autoswitching medium resolution monitor would be the best type of monitor for a JAMMA cabinet so that you could play both standard and medium res. games?

Or you're saying I can get an upscan converter for my standard resolution monitor and turn it into a medium resolution monitor?  Where would I find more info. on getting one of these and doing this?
