I have an NEC 5FG. It is a multisync RGB monitor. I also have the CPU boards for an arcade video game. It has NTSC timed analog RGB output. I want to know if the two will be compatable. I suspect they will, but I am confused: It's my understanding that the vertical retrace rate of NTSC is 60 Hz, and that it is interlaced, yielding 30 pictures per second. But the monitor says 55-90 Hz vertical sync rate. That sounds compatable to me. It's my understanding that the horizontal retrace rate of NTSC is 14 kHz. The monitor says that its acceptable range is 27-79 kHz. Now 14 x 2 is 28, but am I reading too much into that coincidence? Am I wrong about the NTSC horizontal rate? Or is NTSC too low-res for such a fine monitor to deign to display? :-) -- Nick Sayer <mrapple@quack.sac.ca.us> | "Turn around. Stick it out.
