Shoiuld you go to a computer store and ask that question? I ask because it seems to be more helpful, rather than one of us going "yeah just get the NEC MultiSync FE700" (it's my flat screen BIG BOX MONITOR NOT THE "typical" FLAT SCREEN YOU PROBABLY MEAN).

*nod*

Edit: my dad has the other style of flat screen (the one with the thin monitor case) and it changes resolutions okay. It is an IBM monitor.
