I have a Samsung... and one Nividia card.
lolBut, I do have the Datacolor Spyder3 Elite... but have a feeling I never do it right. Damn thing has too many options that I have no idea what they mean... or should be set at. LOL
I think it was that Datacolor Spyder3 (Elite?) my friend used on my monitor to verify its Auto calibrate function.
As for a warm up, the instructions say the monitor has to be on for 24 hours, after burning in running for a week or more. They also say to redo the function once or twice a year. I am pretty good at setting the control panel of the cards, and hitting the button on the monitor to start the process.
