Subject: HARDWARE: CRT's vs LCD's -- comparison?

  I am currently working on the construction of a homebrew VR system
and would like to post a question about my HMD. I realize that most
manufacturers have gone with LCD's for visual input with varying
success in resolution, colour, and FOV. Wouldn't 4" or 4.5" CRT's
alleviate some of these problems?  As I understand it, CRT's provide a
much higher resolution, better colour definition, better contrast? I
might be out on the edge here, but wouldn't a larger screen (4" as
opposed to 2.7"), coupled with proper optics, provide a larger FOV?

  I do realize that CRT's are heavier and larger, and would probably
make the HMD much more cumbersome. But in a situation where detail is
very important, wouldn't the use of a CRT-based HMD be worthwhile?

  Thanx.
