Hello Bob,

I also have a Spyder2.

The Spyder 2 has a bluish plastic filter for LCD measurements (part of the 
baffle). You will find your measurements are rubbish without it.

On the other hand, the filter/baffle should be removed for CRT measurements (I 
used to have one but it blew up last year).

Another thing: you can pry open the baffle to clean the filter if it's dirty 
(e.g. dust or mould).

And, the Spyder 2 does not support ambient light measurements.

Hi All,

I just setup a Spyder2 to do calibration of my Ubuntu box with inexpensive TN 
LCD panels.   I also need to calibrate my XP box with old CRT displays.


1. For Spyder2 under argyll, do you use the LCD baffle when calibrating like 
you do for the vendor software?
2. The vendor's software didn't provide an option for calibrating ambient 
light.   Should I measure with the LCD baffle on?   My I1D2 had a white plastic 
cover that you use when measuring ambient.   Should I use something like that?

Thank you in advance,
