I thought I had a handle on using the Spyder 3 but tonight I hit a wall.
I have a desktop with two Dell 2408wfp monitors. I have them profiled at 6500 2.2 and 120cd.
I have a Dell notebook which I also profiled at 6500 2.2 120cd with the same Spyder in the same room.
First problem is that the Spyder tells me the room is 89cd when run from one computer and 120cd when run from the other. The location of the spyder itself never changed.
I went ahead and profiled all three displays and then using Lightroom displayed a white image.
The two desktop displays show the same color for white where the laptop shows a different one. The desktop compared to the laptop appears greenish, the laptop (not surprisingly) looks a bit magenta by comparison.
Questions:
Shouldn't the Spyder give a near identical reading of ambient regardless of which computer is driving it?
Shouldn't 128, 128, 128 produce the same apparent image on all three displays instead of obvious chromatic differences?
FWIW, the desktop displays have a gamut pretty close to AdobeRGB according to S3Elite software 4.02.
The laptop is limited to approximately sRGB according to S3E 4.02
Win7/64
