Early cards have weird sync frequencies or used fixed frequency monitors so LCD monitors hate them.
Even much newer cards can have issues with LCD monitors. I have a PCI CAD card that does 1920 x 1080 at 60hz but my 1080p 24" DELL doesn't sync to it at that (native) resolution so I have to use something smaller.
