That is interesting. I just recently hooked up the Amiga to a 20" 4:3 LCD (12x10) panel and I must say that it's a problem getting things to look right. Text is very blurry and there's no way to turn the "automagic" scaling features off.
I still have an HD (CRT) television in my house and everything that I throw at it looks great. I guess it's a matter of LCDs having fixed pixel whereas CRTs can make a nice pixel any size it needs. Perhaps once LCD resolutions get so incredibly high we'll be able to make any resolution possible and it won't matter.
