I have a couple of NEC 15" LCDs about the same vintage as the MultiSync 1980sx. They support resolutions at up to 1024x768, and I've never had trouble using them with any of my Macs.
I also have an eMachines 19" widescreen that I picked up cheap last year, I got a nice surprise when I read the documentation (after buying it) and discovered that actually supports the vintage Apple oddball resolutions, such as 832x624 and 1152x870! And it puts black bars on the sides of the image rather than stretching it out. I never thought I'd find myself saying good things about an Acer/eMachines product, but well - there you go.
For what its worth, I have no idea as to model numbers and can't get them, all this stuff is at my parents' place, which is interstate.
