Enable Rotate / Pivot / Portrait Mode on Desktop with LCD?

Request:

Does anyone have portrait mode running on a NON-tablet PC? If so, what is
your graphics adapter and drivers?

Background:

My work as a transcriptionist is done best in portrait mode.

My GeForce FX 5200 "glasses" beautifully with Vista's included driver.
NVidia's Vista beta driver (up to and including the latest) "glasses"
equally well, but the nVidia Control Panel that installs with nVidia's Vista
beta driver has never appeared to include all components, such as rotate,
even though that feature is mentioned in the nVidia Control Panel help
dialogs.

NVidia replied to my specific inquiry with a prefab reply that did not
address my request for information on the seemingly missing rotation
feature.

My hours of testing and tweaking has produced results that generally follow
the successes and failures documented in this newsgroup. More specifically,
my test machines with different graphics adapters all work well with the
drivers included in Vista, some allowing rotation, including the old Intel
815 integrated graphics chipset for which Vista supplies the very capable
Intel Extreme Graphics control panel, some rotatable through all axes and
some to only 180 degrees. (None of these older adapters support "glassing"
because they do not meet the requirements, but "glassing" is not my goal.)

I will gladly purchase a new graphics adapter in order to use my beloved
portrait mode, so has anyone out there succeeded? If so, details, please,
and TYVMIA!
