I say this owning two plasma monitors, they simply don't replicate all features of a CRT, either as well, or at all. If you need zero lag, or multiple resolutions, scans, syncs, etc.? Then you need a CRT. Now, likely not an HDTV, but still, this is something that no digital display does. And we've not even made it to the motion and colour of a CRT.
Every so often someone comes to this board for ****s and giggles. A CRT may "pale in comparison," but you have to be clear what you are comparing. For almost anything new
, obviously, an alternative that could be ten years old, possibly beat up, dusty as hell and in other varying states of condition, well you see where I am going with this, first impressions are going to be killer. But the gap is so wide for the things that a CRT does well, that even something beat up from craigslist can provide an image that far outstrips the free takeaway price that it gets routinely, and it's hard for any plasma to pale by comparison of pricetag. If you prefer your plasma, that's one thing, but that's not what this board is here for and it doesn't speak to what is at hand. You dig?
I was confusing horizontal scanning frequency (which I believe is 33Hz on my XBR) with refresh rate.
This is probably more due to non-interlacing, lack of pixel variance (size, shape, space, all tend to be inequal in smaller or greater amounts on a CRT, which can account for geometry, bloom of brightness/contrast and other inconsistencies), DPI and flicker than either resolution or refresh rate, horizontal or vertical. Computer monitor CRTs do a fine job with readable text, but for the above reasons, even a high quality VGA CRT monitor does not create as readable black-on-white text as a digital display LCD. It is more the nature of the tech, rather than superiority of implementation.

This isn't inhernent to "plasma technology." It may be inherent to a given plasma TV manufacturer's firmware, but there is nothing about dimming of brightness, contrast, or the so-called "floating blacks" that is necessarily attached to plasma image technology. This is a problem that has arisen with digital displays, and has affected various LCDs as well through the years. In an effort to make various products stand out against competition, some engineers had thought it might be a good idea to process images more than their neighbours' televisions, to make scenes more movielike, to provide better viewing under certain lighting conditions, smooth motion by interpolating (120/240Hz), or whatever other doodad of the month is popular. Normally you would want it to be turn-offable, but frequently, simple options like this get left out of first or early implementations, and that does not even factor in whatever hardware or firmware bugs can and do occur. I've got two plasma monitors that have no automatic dimming at all, however, nothing inherent with the technology at all.
