VGA monitor driven by a CTC2 chassis

[Zenith6S321]

The CTC2B user controls affect the VGA monitor picture. The user can adjust the brightness, contrast, color level, hue, and fine tuning which all operate as the original sets CRT. The V and H hold do cause the scan converter to break up some of the time and display a No Signal between attempts to display nonsense. Careful adjustment does result in a stable picture. The possibility of driving a VGA monitor using a converter allows a modern monitor with a color gamut similar to the 15GP22 to be used to provide set that operates as the original. Anyone have any suggestions on a monitor that has the same color gamut? Here are some more pictures showing the affect of adjusting the above controls. I have seen claims of 92% NTSC to up to 200% NTSC color gamut, whatever that means.
