No they aren't.  If that were true they would mess up if you turn them (horizontally) 90 degrees, or move from Canada to Equador.

If you're in a place where the magnetic inclination (dip) is 45 degrees -- say, FLorida or Israel, and your monitor is oriented east/west, turning it between landscape and portrait affects the applied field direction in exactly the same way as swiveling it 180 degrees does.

It if't a particularly sensitive monitor you may need to redo the convergence adjustment if you do any of these motions, but it certainly should not be a problem to make it work.
