I know this sounds like a simple problem, but it has a big productivity impact, and I would be very grateful of a solution (or suggestions):
With UltraMon (brilliant!) I am running 2 TFT's side by side. 2 X 1600x1200. Quite honestly, a display of 3200x1200 is much less helpful than utting them in portrait and getting 2 x 1200x1600 or 2400x1600. This is much better for reading PDFs, emails, word documents, desktop publishing, etc. The 1600 "y" scale really helps get the whole page up on the screen at once.
Another benefit of this orientation is that eye scan/movement is reduced on this "squarer" rather than "wider" format.
PROBLEM
Unfortunatey, Microsofts's implementation of ClearType and the ClearType PowerToy, works ONLY with TFTs where the RGB pixels scan horizontally. ie. landscape mode. If the displays are turned portrait, cleartype struggles.
Is there any API hack you can build into UltraMon to solve this ClearType issue?

Probably not, I'm not familiar with ClearType internals but doubt that a third-party application could help with this.

ClearType is based on the way LCD displays work.
I don't think it really can work when the display is rotated.
I say this due to the way the RGB elements are arranged and what clear type tries to do with them
you are going from say
RGBRGBRGBRGB
RGBRGBRGBRGB
RGBRGBRGBRGB
RGBRGBRGBRGB
to
RRRRRRRRRRRR
GGGGGGGGGGGG
BBBBBBBBBBBB
RRRRRRRRRRRR
GGGGGGGGGGGG
BBBBBBBBBBBB
Clear Type tries to "Hint" text with use of the
near by "Sub Pixel" like RGB RGB
turn ON [__B][RGB]
or [RGB][R__]
and so on to add some "smothing" to the shape.
but if the pixels are RRRRRR then which one do you pick??
I hope this is understandable.
yeah I am sure it "kinda" works in poriat mode but...

Yes, I'm aware that the existing Windows ClearType API is "hinting" in the x-coordinate so that the x-resolution is effectively trippled. The "y" is unaltered.
This is very effective for European fonts/reading because we read in the horizontal direction and the additional resolution in the x coordinate helps.
The trick in portrait mode is to stop hinting in the "x" and instead hinting in the "y".
The question is whether Windows XP/2003 can be tricked into doing the "y" hinting and stop the "x" hinting.
I understand that Vista can do this. But can Xp/2003 be "tricked" to improve portrait reading?

Hinting in the Y direction isn't really any help, because that's not the direction that needs the extra resolution. Even if you could get it to work, you'd still get none of the benefits.
If you're running portrait and not happy, you'll just have to turn off ClearType. :(
