<<<And does anyone have an idea what 1953 refers to? The year?>>>
Yes. NTSC has been around for a powerfully long time.
That was the year they went from "Illiminant C" to "Illuminant D" as a color standard. Illuminant C was a mathematically perfect color standard for color television except for one thing. Everybody except two color-blind people in Schenectady saw as being too pink. Illuminant D was daylight. It's basically the color things are on a clear day between 10am and 2 pm. We've been using that ever since.
I don't want to destroy your fuzzy-warm any more than necessary, but all these color calibrations inside the monitor depend on at least one of them being calibrated to a color standard machine like a Minolta, or a Philips color analyzer.
The monitors come out of the box really close, but monitors, especially glass ones, don't stay that way.
Oh, and no, you still have to buy a Color Television Monitor. You need somethng that hasn't been through the computer's scan conversions and gamma brightness "corrections." Just as a simple example, the canvas view almost always drops one of the two television fields. This can be a surprise the first time you see the video on an actual television monitor and there are things there you've never seen before.
