Thanks for the fascinating info. A lot of this stuff certainly wasn't
obvious to me. I knew there was a big difference between CRT and LCD
technology in general, but what I find surprising is that there's so
much difference between TV sets and computer monitors that employ the
same technology (i.e., CRT TV vs. CRT computer monitor, LCD TV vs. LCD
computer monitor).
