color calibrate on two VDU's after lion upgrade

Hi,

I have just upgraded my Mac Pro from Snow Lepeord to Lion. All seems to have gone well after the 33min upgrade process completed.

Just noticed that my two identical BenQ HDMI attached monitors are showing different colours (colors) / apprearance. I have tried to change the setting in Display parameters, but although two calibrate windows appear, the right (primary desktop) screen is the only one affected by any changes, even if I try to change the left screen options box.

If I create a new calibration profile, no matter whether I select it on the left or the right screen, you can not independantly select a profile for an individual screen.

Seems to be a problem that has just come with Lion. Has anybody else seen similiar issues, and know a fix or work around?

Just ran the ColorSync application and it reports an error with the dfault BenQ profile

When I Verify:

Checking 60 profiles...

/Library/ColorSync/Profiles/Displays/BenQ V2400Eco-000009D1-0000-7D02-0000-544500000000.icc

Tag 'cprt': Text tag has an incorrect length.

Verify done - found 1 bad profile.

When I Repair:

The file is locked. Could not be fixed.

Repair done - 0 out of 1 profiles fixed.
