Excellent this is one of my fav subjects, me like to say I've experienced a lot of different Video cards in my time, and think it would be nice if I shared my findings.
This is for people who want to purchase a videocard for interfacing to an Arcade monitor, if your aim is to use a PC monitor you can ignore most of this section.
Each card will be divided up in its good/bad points.
Firstly lets clear up the different types of Arcade monitor:
Standard Resolution
This has a horizontal scanning frequency of 15.75khz (VGA is 31.5khz) and a vertical frequency of (49hz to 62hz) the resolution normally is 336x240.
Extended version of this monitor can achive 512x288 at 53hz.
Most JAMMA games used this type of monitor.
Medium Resolution
This has a horizontal scanning frequency of 24/25khz and a vertical frequency of (55hz to 60hz) the resolution normally is 512x384. Sega games are 496x384.
Currently I am using a Voodoo Banshee card, and must say I am extremly happy with the results.
ATI Cards
I tell you ATI wasn't very smart having most of there video cards feature 'Rage' in there titles, its a consumer nightmare!
ATI Rage 128 and ATI Rage have nothing incommon, only similarities is in the name.
ATI Rage 2/Pro. (Mach64 internal clock)
These videocards where once considered the king for MAME Arcade monitor support.
This was the first videocard to have a 15khz 640x480/16bit colour mode (courtsey of Brian Lewis of PC2Jamma project), and was soon recommened by everyone who wanted to hook a videocard to an Arcade Monitor.
Advantages
* MAME 640x480 15khz mode at 8 or 16bit color (running at 30hz update, this means games run at 30fps, suitable for Vector games).
* MAME 640x240 15khz mode at 8 or 16bit color (running at 60hz update).
* Excellent picture quality on Arcade Monitors.
* Full MAME modex support for other NTSC/PAL modes.
* Good DOS support (VESA2 linear framebuffer).
* Motion Compensation on some models (Expert@Play/Work/98) for DVD playback.
* Very cheap!
