unless you can find one that has been designed to have the

Huh? Can you elaborate a bit on that, Arfa?
Hi Smitty. Lots of the LCD monitors used in airports and train stations
etc, are used in a 'portrait' fashion, and often appear to be pretty
'standard' looking types, turned on their side. You also see them being
used as menu displays, alternated with advertising material, in
restaurant windows. I guess that whatever is driving them may well be
producing a picture that's rotated by 90 deg, rather than the drive being
normal, and rotation taking place in the display. Until you came up with
this question, I'd never really considered the 'mechanics' of how it was
being done.

Good thought Arfa, but I've always assumed that the image was flipped on
the computer before it goes to the monitor. Otherwise you would have
streching problems unless you designed your video for being flipped this
way and after all of the trouble of doing that you could have just flipped
the video.

I think you're probably right Michael. I guess, thinking about it now, that
the data for display is formatted 9:16 in production, and then rotated in
software to be output at 16:9. Turning the display through 90 deg then makes
it display at the originally created 9:16 again.

Most modern video card drivers allow you to do this, we've got some LCD
monitors at work that are mounted on a swivel, you can run them either
horizontally, or vertically and the driver will display things
correctly, there's no flipping done in the monitor itself.
