Most 22" use the same panel made by CMV optronics or something. If you see the Viewsonic, CMV (Chimei), Proview and Asus brands they all use the same panel as the Dell and cost a little less. I have a Chimei brand monitor and it really is fantastic. I picked it up for 300E, it can be had for about 230E these days. I highly recommend getting one of these monitors with this particluar panel. Even though it's only 6 bit the colours are very clear and you can't run it at full brightness because it's just so bright. So the backlight should last a good few years.
For anything that has to run in 4:3 or 5:4 mode, graphics cards these days can add black bars to the sides and run in that res and it's fine.
