On Vista SP1 (Release Candidate v.668), I have had no problem with the
fade to black or even sleep mode messing up the LUTs. That is
assuming I correctly understand what the -V switch does.
D:\argyll\bin>dispwin -v -V LeftLCD.cal
About to open dispwin object on the display
About to set given calibration
Verify: 'LeftLCD.cal' IS loaded (discrepancy 0.0%)
Calibration set
About to destroy dispwin object
... that is after coming back from sleep mode in the morning.
