I have a 94' DEC 21" computer monitor that may have had 2 years
of actuall use on it.

some component died inside but i think the CRT is OK >? it
looked great just before the caput.
the CRT seems very high quality, flat, black, anti-glare coating,
i believe it uses trinitron technology as it has the 2 aperature
wires at the middle thirds of the screen.

Are there any projects people use these for or usually just trash
them ?

Trashing them is often illegal. We take them in for recycling.

I fix them and use them, nothing beats a good flat Trinitron CRT, and if the
tube is in good shape the rest can be repaired.

i picked my sony E200 trinitron from the street and after a few popped
electrolytic caps were replaced it is still working now (1 year on).

Unless you already have experience fixing monitors (or TVs)
this is likely to be a major problem. It may be worth your taking a
quick peek inside, but in general this is not a good choice for a
home repair job.

If the problem is that the crt is too bright, take a look at this thread:

http://icrontic.com/forum/showthread.php?t=19549&page=14

I was able to fix two Dell P991's by just reprogramming their flash with a
lower
G2 voltage setting.
