Yep, thats what I am using. DVI-D on Samsung, into Thunderbolt on Mac.
if I switch on the monitor, and plug in the Thunderbolt, I get the snowy cliffs desktop page showing on the Samsung.
If I press the side buttons on the Samsung I get the five "Picture, Colour, Size & Position, SetUp&Reset, and Information" options.
I navigate down to "SetUp&Reset" and press the right arrow button, and highlight "reset".
If I press the "Auto" button, I get a message saying "Auto Adjustment not available".
If I press the right arrow button, I get the "No/Yes" option. I navigate to YES, but there is no button that I can see that will activate the YES - the "Auto" button simply gives same message saying "Auto Adjustment not available".
buttons available are
X - press shows menu, press again removes menu
UP arrow - move selector up
DOWN arrow - move selector down
RIGHT arrow - moves to right, nothing more
AUTO button - press the "Auto" button, I get a message saying "Auto Adjustment not available".
POWER - on off only.
Its like there should be another button that "accepts" the command.
