HDMI should either give a perfect display, or absolute garbage squirming all over the screen. > I remember in the bad old days when I had a regular job in an office, > that monitor picture quality varied quite a bit.

Well, maybe I don't have any cheap LCDs, but as for spatial, I think they are MUCH better than shadow mask CRTs. Compared to a B&W CRT, or the Tektronix shadow mask-less CRT, the old shadow-mask tubes just never cut it. The problem was the pixels had no relation to the holes in the shadow mask. LCDs, when run at their native resolution, avoid this problem completely. The computer pixels exactly match the screen pixels, period. (If you ever mis-set the screen resolution so it has to interpolate, you will see the difference. They do amazingly well like that, but definitely sharpness suffers.)
On the other hand, for color gradation work, like processing very bright and detailed photographs, I think CRTs with all-analog intensity control still outperform LCDs. > If > I spent buckets of money on an LCD monitor, would CAD drawings look > better or would I just have a better movie experience?

I'm not too impressed with the HP, some of the text on the EMC window is "fuzzy". Some kind of quirk on that HP. Everything else here is still CRTs, many are essentially dumpster finds.
