i don't know, I don't have an LCD. I WISH I did. I could throw this f*ing CRT out the window, it is a pain on my eyes and I'm sick of the dam thing. But I can't afford an LCD at the moment.
I have got an lcd, and regret it. The quality of crt's are so much better. I'm not an artist or photographer, but I do have a bitchin home cinema

It's the same with TV's - everyone thinks plasmas are oh-so-cool, but it really depends on whether you want a monitor/tv that gives a good picture, or a monitor/tv to show off with.
If your crt is hurting your eyes that much then get a glare guard thing for like 15 quid.
For those of you who dont believe that color is better on crt - I googled and found an article that was very biased towards LCDs, but said this:
For most office tasks the color and video quality of both LCDs and CRTs will be equivalent. For high end color graphics, CRTs can offer some advantages because LCDs can only display the colors available in the pixels, and so they can have less of a color depth than CRTs. Some LCDs (low cost, low resolution) have pixels that respond too slowly for accurate video rendering, and some tearing of the video image can occur,
which usually is not an issue for CRTs.
Your three shades of blue problem could probably be attributed to a "rounding error" as the lcd can't display two colours that close together it ended up rounding one up and one down.
3 shades of blue is not perceptable to the human eye - else we would be buggered doing any kind of blending
