The way computer LCDs look outside of native resolution is what bugs
me. I have two crts on kvms at home and haven't upgraded either to
LCD because not all the systems I use will support the native
res on the LCD I would buy (probably 19" or more at 1600x1200 which
is what I use at work) so I've stuck with CRT. I play with vmware
quite a bit both at home and at work but I can't switch to fullscreen
mode on the fly using an LCD because the display either freaks out or
looks horrible. It works fine at home on my CRTs. I've seen discussions
about color issues and gaming issues but those don't really apply to me.
(20 shades of blue is still just blue to me.)

Nice. Have you considered selling them and giving the money to charity?
You might get some interest here since LCDs are easily shipped.

Yeah, my friend's HDTV suffered from both. If he dimmed the lights and
you sat right in the middle of one particular couch, it looked GREAT.
If someone else wanted to watch, they got a degraded view. Not a great
home theater setup for multiple users.

The LCD projectors we use at work look pretty good even on a wall and
will take either a VGA or composite input. (one takes component input)
They probably don't have the sort of duty cycle I'd want for a home
theater but they look pretty good. I assume I could use the same
screen or wall for multiple projectors (not at the same time of course)
so maybe a couple of grades are an option.
My CRT just keeps lookin better and better! Maybe I should find someone
locally with one of the biggies (44" or so as I recall?) who wants to
upgrade to newer technology. I've had my 35" for 8 years and I'd swear
it looks just as good now as it ever did.

Smart! Maybe park a CRT in the corner for regular viewing?

Yeah but OLEDs have short lifespans and are supposed to very cheap to
replace just the screen while keeping the electronics.

Ooh, I'll check it out. Has anyone finally implemented my idea
for putting speakers on a bus and making them individually addressable
so you can "rotate" them depending on whether you want to watch TV
or listen to music in another chair? When left and right for music
come to me from front and rear it bugs me.
