Spyder2Pro and Samsung SyncMaster XL20

Spyder2Pro and Samsung SyncMaster XL20

2007-06-18 by Ronald Janowsky

Last Weekend I hat the opportunity to spend some time with
a Samsung SyncMaster XL20 monitor. The Samsung has a LED backlight
which mades it a little bit special. Samsung claims that the gamut of
this display will cover AdobeRGB completely. My first test with the
Spyder2Pro (V2.3.2) were quite positive, but the profile (Native Whitepoint,
Gamma 2.2) looks a little bit off concerning the gamut. I found the same
in a review at X-Bit Labs:

After I had this discovered I profiled the device again - same result. My next
attempt was with the included Eye-One Display2 and Eye-One Match V3.6.1 Software.
In this profile the gamut of the display quite nicely covers AdobeRGB. Is it
possible that the differences in gamut between these profiles indicates that
the Spyder2Pro device/software combo has some problems with LED backlight displays?
All the other LCDs I profiled with the Colorvision hardware/software never showed
such a behavior.

Comparing the Spyder2 to EyeOne Display and guessing which is closer based on which you hope is correct isn't really a scientific approach. When we compare various retail monitor calibrators to laboratory bench colorimeters (devices that cost about as much as a car; not in the end user price range) the Spyder comes out about as accurate as the others. The point if greatest variability (in all of them) is the green, which is not surprising, given that the green in AdobeRGB is the most saturateed primary, outside of ICC Lab space, in fact. If its any consolation, these are greens so intense you eye can't really distinguish them either...
