I see, thanks very much for the info.
I have been looking through lots of what are called "presentation monitors". Some of them seem to be able to go to what I need, while still possessing resolutions within reasonable desktop limits.
What do you guys think of these?

I have owned several of these NEC Multisync XM monitors. They are absolutely amazing. I think they are the best type of display solution that you can get for an All-in-one Cabinet.
You can use them for your normal computer desktop applications. You can even use them for PC gaming (Halo, Doom 3, WOW, etc...) since they will do PC resolutions.
And you can also display arcade resolutions on them if you use Powerstrip with an ATI Radeon video card, or with just an ArcadeVGA card from Ultimarc.
The magic specs here are: H Freq 15-50 Khz. 15KHz H-Frequency is CGA for oldschool arcade resolutions.
25KHz H-Frequency is EGA for newer arcade stuff like some of the Crusin' games.
31KHz H-Frequency is VGA which is 640x480 computer resolution
31-50KHz H-Frequency you are going up 800x600, 1024x768, and anywhere in between...
Me and Huib1 have experimented with these monitors using Powerstrip with a Radeon 9250 video card. He has one in his cab running the correct arcade resolutions for each game. I have build another cab for a friend and put an NEC monitor in it, but running normal PC resolutions in MAME. He is very happy with the results.
The dot pitch on the screen in not quite as coarse as the regular arcade monitors... but is not as fine as the normal PC monitors. It is somewhere in between, which is why both desktop applications and arcade res application look so good on it.
The biggest downside to these monitors is that they are usually large, heavy, and cube-shaped. They will not fit in most standard cabinets. I had to build a Midway-style cab and make it 4.5 inches deeper than normal for the monitor to fit in there. Huib1 has a Lusid-style cab, and it just barely fits in there. I strongly discourage trying to decase these... they are very heavy, and have several PCBs inside, very scary...
Also, they can be rather expensive.
