Hi there,

I have an Alienware Area 51 with 3 graphics cards in SLI and 2 monitors attached. One of the monitors is a Viewsonic TS2340 which has been working fine as the secondary monitor for several months.

However, recently I have found Tablet Mode is greyed out and none of the touchscreen functions work anymore on the TD2340.

More than anything, this is not a showstopper, but it is irksome. Since it was last working I have updated Windows 10 (standard updates which are pumped out) and installed no new software - before the TD stopped working.

Also, Windows Properties now says no touch or pen devices attached and the Touch Screen settings panel in control panel is missing.

Any ideas?

System:
Alienware Area51 R2 latest drivers
NVidia GeForce Experience updated (triple SLI config for GTX970)
32Gb RAM
SSD and HDD
Windows 10 Home 64 bit
