Re: Philips Dexscape TouchScreen Problem

Something like that Phil, yes.

As I said if I extend my desktop on to the touchscreen the
touchscreen does nothing (apart from displaying the desktop of
course), but if I clone it then the touchscreen works but its out of
alignment. In the center of the screen it seems good but as you move
out it gets worse.

If I match the resolution to 1024 x 768 then at the lefthand side of
the touchscreen its accurate but the further right I go the worst it
gets!

Very odd...and very annoying.

Any tips?
Darren
