Just got a refurbished one yesterday and I am trying to calibrate it with my eye1 D2. If I just use the cinema lcd in the display menu for monitors it is very bright and cool looking for temp. I run the program in the advanced mode and set the brightness at 110 Lum.s , 6500k, 2.2 gamma, and I ran it about 4-5 times and it came back with awful results. Then I ran it again and it worked? What the hey? However I don't trust it. How long do the calibrator pucks last? What about my video card, could that be the culprit? What can you do to test a video card? Plus the two screws on the monitor that tighten the screen swivel can't be tightened much more and the screen barely will hold at an angle. I also have 1 bad pixel down near the bottom, not a deal breaker. Should I send it back? I must say though that the screen is awesome, just need to figure out my weak link here. any thoughts please?
