Hello

i have a question with chromapure meter Correction button

better to enable this option? it's for Idisplay pro or standard ? or both are good to enable this option
because all settings are 0
if i understand field meter = Idisplay meter
and reference meter is other material ? if i don't have a reference meter , this is possible to use the meter correction?

thank you

ChromaPure has the option of correcting a meter's performance (called a 'field' meter) with a reference device (the reference meter).

See the section here called "why buy two meters?" for more explanation as to why you'd do this:

ok do you think it 's possible to have a better autocal with EyeOne Display 3 meter ,video projector JVC RS49 and lumagen radiance 9x9x9 calibration device

i'm not a specialist but here my adjustment:

4K eshift disable
preset : natural
6500K
all in RGB Level video (chromapure/VP/Scaler)
Advanced Color Gamut :2
Reference Gamut Rec 709 / dE Methode CIE94
Gamma method 2,2
Matrix size 729 points
Measure post calibration 125-729 colors

oppo is OFF

meter : front projector screen

i disable all corrections with scaler lumagen /video projector
i launch directly auto cal and when it"s finish, i adjust contrast and luminosity with lumagen pattern
here the result: i can't have a better CIE specially for green, other post colors are not perfect with reference color.

i forgot a step?
after autocal do you adjust Advanced Colormanagement or normally you don't have to change any color??

thank you in advance

Please send a full calibration report and copy/paste the data in the activity window into a text file and send that too.

Send to support@chromapure.com

To diagnose the problem I need more information.
