Thanks for your patience Chis - I do appreciate it.
nVidia have just released a Win 8-specific driver for my GT 220.
That PLUS ST2220T Win 7 Driver PLUS fiddling with "Calibration" have given me a workable set up.
Win 8 has 3 new (compare Win7) Swipes:
_Swipe from Top Downward (App Menus) - this works quite well.
_Swipe from Right (Charms) - Works quite well.
_Swipe from Left (App thumbnails) - works but temperamental - The problem is the Bezel.
Through practice, I have got an "educated finger" (No not THAT finger 🙂 )
I'm sure that all these could be addressed by building a "2-3mm edge bias" into the driver.
Thanks for the site reference,
