The only problem with my big (37") TV screen that's been doubling up as a monitor is that its text display isn't good; using programs with unadjustable text size (such as Eve Online) causes serious eyestrain. So I looked around for a reasonable size monitor and came up with a 22" LG E2250. It's an 'LED' monitor, an improvement on pure LCD.
Connecting via a DVI-D lead was no problem, Windows7 auto detected and multiscreened - that's where you move the mouse off the edge of one screen and it pops up on the other. The specific LG driver needed a nudge to install.
Text is now clearer by a lot. The LED improves on backlighting, making the picture brighter.
