No.

Yes, perhaps in some points even a little better
(Try OS/2, Version 1.2)

For DOS, I don't know some. But MS-Windows, Version 2.11 can utilize
the 8514-adapter and therefore all Windows-programs can use the
resolution.

I you program yourself, you can use Borland's languages (C,PASCAL,PROLOG)
together with the 8514 under Borland's graphic interface BGI.

>Are there choices other than the 8514 that work well?

For MS-Windows, you can get boards with resolutions up to 1.6k x 1.2k,
but they are very expensive. There are a lot of black-and-white
video-systems around with resolutions about 1.2k x 1k, but they have
often compatibility problems, when working with standard applications
under DOS. Beside that, only for a little group of boards are driver
for OS/2 available.
