[argyllcms] Calibrator correction for Eye One Display 2 & GB-LED Backlight LCD Monitor?

Hi all,

 

I am currently using an Eye One Display 2 colorimeter with the latest
argyllCMS and dispcalGUI to calibrate a NEC MultiSync LCD1990SXi graphic
arts monitor.  I'm very pleased with the results-THANK YOU!  I'm a photo
enthusiast/home user and appreciate good color, but have a hobbyist's budget
and reasonable expectations.

 

The NEC has become dim over time and I'm looking to replace it soon with an
Asus ProArt PA249Q which, like the better known Dell U2413, has the LG
LM240WU9-SLA1 AH-IPS panel. But I have one problem.

 

This relatively new panel has a GB-LED backlight (improved gamut), but from
what I've read, the curves are sufficiently different that I would need to
either go buy a new calibrator (X-Rite wanted to sell me the i1Display Pro -
$229), or get a new correction matrix to successfully use my existing
colorimeter.

 

I checked dispcalGUI's Colorimeter Corrections Database, etc. and found some
CCSS and CCMX files for the Dell U2413, but none that support the Eye One
Display 2.

 

 

QUESTIONS.

 

Does anyone have a corrections file for the Eye One Display 2 and a GB-LED
backlight display? Or perhaps be thinking about either making one, or
including GB-LED support into argyllCMS/dispcalGUI as a new mode?

 

If not, any ideas on how to make or fake one at home?

 

One idea.The monitor claims  to come factory calibrated within 3 delta E
(fingers crossed.) Is there at least a way to make a correction file that
uses the factory calibration as a trusted baseline so I can always get back
to that even if the colors drift over time (or if I want to customize the
calibration)?

 

 

Thanks very much in advance for any help!

-Al
