The Wide Gamut CCFL and RGB-LED readings showed - as expected- even larger deviations. As soon as the spectra differs too much, the device tends to report wrong readings. The spectra of a white LED unit differs a lot from a standard CCFL it replaces and the colorimeters are trained on a specific panel type and spectra. However, on a white LED unit, the readings differ a lot from the reference. All selected colorimeters showed an acceptable performance on the 72% NTSC CCFL display. We used the "best" set of the evaluated units to perform some quality tests. However, both devices show much better inter instrument agreement. Even the 3E max tolerance of the DTP94b or EyeOne pro can be too high. I will summarize the findings we had so far:ġ) Inter instrument agreement between at least 20 units:Īs recommended bu others, one should only make use of one (1) EyeOne D2 or SPyder 3 unit for all installed displays, because the tolerance between these devices are much too high to get consistent results. 108% NTSC display with LG S-IPS and RGB LED backlight 102% NTSC display with LG S-IPS and CCFL Backlight (extended WCG) 92% NTSC display with LG S-IPS and CCFL Backlight (WCG) 72% NTSC display with LG S-IPS and pseudo white LED (blue LED + yellow 72% NTSC display with LG S-IPS and CCFL Backlight Test have been done on stabilized displays with the following base specs: We´ve used a Minolta CS200, CS1000 and CS2000 to get reference values.
