think the m200 is the only tablet with 1400x1050 I have ever heard
mentioned..

there was a discussion about resolutions here a year or so ago... google
groups time (they allow searching old threads)

here's a starting point

Are you asking about the tablet screen or the video card capabilities?

fwiw, I use my 1024x768 fuji with a 1920x1080 samsung LCD TV/Mon, so,
another consideration if you can't find what you are asking is to assure
that the tablet's video card will support both large external screens as
well as offering a variety of working resolutions.
