Two Monitors - cannot rotate screen

I have an Aspire Z3731 all-in-one touchscreen PC plus an Acer X223HQ external (second) Monitor.

 

I am trying to rotate the screen on the external monitor to portrait orientation...but with no luck!

 

In point of fact I am not even able to rotate either screen...

 

I have the latest Intel driver but still no joy.

 

The Shortcut keys - ctrl/alt/arrow key cause the screens to 'think' they have done something; they both go black for a couple of seconds and then ask if you wish to retain the new configuration, but they dont actually do anything in terms of changing orientation!

 

Any help would be very much appreciated.

 

Thanks in advance!
