CRT has a lousy on/off CR compared to LCD. !
You have got your definitions all mixed up. There are basically 3 types of contrast:
- On-Off contrast: Full White versus full Black. CRT has by far the highest, up to 100000:1 and more depending on calibration. LCD is poor with typically some hundred to 1 up to > 1000:1. Easily 10 to 100 times less than CRT!
- ANSI contrast: Checkerboard white versus checkeboard black. CRT is rather low here with typically 100:1 or so. LCD can be quite some higher. At least some hundred : 1.
-Intrascene contrast for natural images (not checkerboards, not full black or white): Is a mixture of ANSI and On-Off depending on content. CRTs will show anything from ANSI to several 1000 to 1 and more depending on content. The lower the APL of the content the higher the contrast from CRT, easily beating LCD for not bright stuff. No display is best for all kinds of images. Concerning contrast with images as seen in film CRT is the technology to beat. No other is on the market which is better. Concerning other image aspects other technologies can be better.
CRT is bad because:
1) It's fuzzy and soft, not quite as sharp
Not as sharp as DLP or LCD. Fuzzy? Good CRT is sharp, smooth and film like, not fuzzy.
2) I get headaches from the refresh cycle, bad flicker!
Depends on HZ. Can be run at 72 HZ or 120 to eliminate flicker.
3) convergence, no CRT is 100% perfect (plasma is 100% perfect)
Convergence is not optimal. Agreed. Needs not be bad, though.
CRT has no banding issues related to the CRT principle. On the contrary. To be sure if there is banding in a source the high end CRT is the way to tell since it has no bith depth issues as an analogue display unlike all digital displays where display issues might cause the banding (this assumes the CRT uses no bad quality digital processing inside which can add banding, of course, in the digital domain).
5) floating blacks, dc restoration issues
High end CRT does not have it.
6) can't hang it on the wall
No image quality argument.
7) not cool, impressing the Jones's is very important!
Educated people are impressed by image quality, not meaningless form factors. :-)
8) You just don't get the "punch" of a plasma
Depends on image content. Low APL material has more punch on CRT than any digital displays.
9) Pixels bleed, if you set the brightness too high you never bloom on plasma
It's not dummy safe. You are supposed to calibrate it properly, like other technologies. Dumb argument.
10) barrel distortion, which is why a CRT will overscan
Not a big issue with high end CRT.
11) can't get 1:1 1080p
Since it has no pixels the 1:1 is meaningless. If you mean you don't get the same MTF as on LCD or DLP you are right. It will be softer.
12) size limited. Largest CRT HDTV is the 34" Sony. Way too small!
Right. You can use a CRT projector if image size is so important.
No technology has it all. And quality within the same technology varies greatly from cheap product to high end product. The price performance ratio of CRT monitors is very good if you can live with some of the restrictions (such as image size).
