The LG seems to be the best one you have! I also bought a Dell in 2001 and that one lasted me until 2013 which was when I got the Viewsonic. The Dell was a big 1600x1200 screen, I miss it! I dont think they make that size anymore.....
That old Dell was $1700 back in 2001!
Looks like this Sony from 2005 is going to outlast all my other ones lol. It was less than $600. Only inconvenient thing about it are that the power and control buttons are at the bottom!
Do you connect all your screens to the same computer and use them all at once?
