yes, it is very strange. Today it is working fine.
I did not make any change........well I did update the BIOS of this PC's 
motherboard...........I dont think it had any fixes for USB or anything.
I ran a quick calibration using dispcal and it too completed without any 
error............very strange.
Now while I have your attention, Graeme, what is the best way to prevent 
greyish blacks? 
even with this command........
dispcal -v -y c -q m -w 0.313,0.329 -g 709 -p 0.5,0.5,1.7 -f1 -k0 g70-1
......while watching movies after dispcal......fade to black scenes 
have elevated brightness. Also, the overall image lacks "punch" . 
I think it is reducing the contrast/brightness to correct the greyscale or 
something.
 Regards,
Rajiv Mehra

It all seems to be working as expected.

You need to capture the debugging output when there is a problem.
