VGA monitor driven by a CTC2 chassis

I have never seen 200% NTSC - don't believe it's possible except as a typo.

Monitors that do better than 95% or so NTSC (or Adobe RGB, which essentially has NTSC green and somewhat less orange / more saturated red) will be so close to the 15GP22 that's it's not worth worrying about. The standard sRGB or HDTV monitor covers about 70% of NTSC, mostly due to the yellower green. In fact, since LCDs don't have the purity problems that a CRT can have, and also have blacker blacks, they will do as well as the 15GP22. especially in the lowlights. The only drawback I can think of is that wide gamut monitors are generally more expensive.

By the way, 70% is measured on the 1931 chromaticity diagram, which does not correspond to uniformly perceptual color space, so you are really losing considerably less than 30% of perceivable NTSC color space in a HDTV; but the differences in greens and cyans should be noticeable.

Probably just some sales hype. Here is a link. It is a pico-projector that uses lasers as the light source.

Scroll down and it says: "◦Color Gamut: >200% NTSC"

With lasers, greater than 100% NTSC for sure, but greater than 200% is doubtful.

Plus: you don't WANT so much greater than sRGB/Rec 709 for video sources, or the colors will look too saturated, so the colors should be mixed by the circuitry to simulate Rec 709 primaries;
Plus: the picture from this dim device will be washed out by the least amount of ambient light unless you keep the image very small, so whatever colors it starts out with will be desaturated in actual use.

So: hype? Yes indeed.

So, if I understand correctly, an LCD with close to 100% Adobe RGB is the probably the closest gamut match to the 15GP22, but may be expensive. And since its image size cannot be adjusted it will have to be about a 15" diagonal 4:3 or a 17" 16:9. Seems like most monitors are big these days so it may be tough to find one that meets this.
