Olen aiemmin kalibroinut profiloinut näytöt Eye-one Display 2:lla. Kun nyt sain kokeilla Colormunkia niin katsoin että näyttääkö samoja lukemia. Ei näyttänyt. Mikä tämmöisten mittareiden tarkkuus on ja kuinka suuri ero on merkittävä?
Alla on mittaus ensin Eye-onella ja toinen Colormunkilla. Voiko tuloksista vetää sen johtopäätöksen että toinen näyttää väärin vai onko ero käytännön kannalta merkityksetön?
ossi@x17:~$ dispcal -yl -r
Place instrument on test window.
Hit Esc or Q to give up, any other key to continue:
Current calibration response:
Black level = 0.34 cd/m^2
White level = 104.27 cd/m^2
Aprox. gamma = 2.23
Contrast ratio = 310:1
White chromaticity coordinates 0.3361, 0.3474
White Correlated Color Temperature = 5350K, DE 2K to locus = 2.6
White Correlated Daylight Temperature = 5350K, DE 2K to locus = 2.5
White Visual Color Temperature = 5293K, DE 2K to locus = 2.5
White Visual Daylight Temperature = 5405K, DE 2K to locus = 2.3
The instrument can be removed from the screen.
ossi@x17:~$ dispcal -yl -r
Set instrument sensor to calibration position,
and then hit any key to continue,
or hit Esc or Q to abort:
