Final Update
I did try re-installing the beta 2.2 driver and waiting for up to 15 minutes - no go.
Re-installed the 2.1 driver. I get the white, red, blue, green flashing for 3 cycles, then a new icon is displayed, a computer and monitor with a blue USB cable coming in from the right side. This displays, jumping around the screen like a screen saver for many minutes, possibly 5 or more and it starts to work.
Bottom line - for me the beta 2.2 driver does not work with a single external monitor, but the stable 2.1 driver does.
