Easiest way to check if the tv drifts over time?

[Anonymous]

i never learn this program 🙂

i think this subject has been up before but i cant remember of find it.

my last 9200 patches 3D LUT is from July last year and i still using it.

is it possible to check if the 3D LUT is still as accurate as it was  7 months ago ?

and also to see how much the tv has drifted over this period?

why i ask is if i dont know if its worth it to run a new 9200 patches calibration with the time it takes

picture still looks amazing

i think i found it

“Report on calibrated display device”

then i unticked “disable 3d lut” from madvr testpattern generator

this is after 7 months

not that bad right?

18:37:15,556 Current calibration response:
18:37:15,558 Black level = 0.0000 cd/m^2
18:37:15,558 50% level = 25.19 cd/m^2
18:37:15,559 White level = 124.31 cd/m^2
18:37:15,559 Aprox. gamma = 2.30
18:37:15,559 Contrast ratio = 1:1
18:37:15,559 White chromaticity coordinates 0.3122, 0.3274
18:37:15,559 White Correlated Color Temperature = 6546K, DE 2K to locus = 3.9
18:37:15,561 White Correlated Daylight Temperature = 6549K, DE 2K to locus = 0.9
18:37:15,561 White Visual Color Temperature = 6404K, DE 2K to locus = 3.8
18:37:15,561 White Visual Daylight Temperature = 6581K, DE 2K to locus = 0.9
18:37:15,562 White drift was 0.000000 DE

but this test only checks white ballance and gamma

i would like to know if colors has drifted

You can run a complete verification via the “Verification” tab. Enable “Use simulation profile”, set it to “Rec. 709”, enable “Use simulation profile as target” and “Enable 3D LUT”. Set tone curve parameters to the same ones you used when creating the 3D LUT.

thanks i will check it out

one question is if the newer versions of dispcal will improve calibration results over the older versions?

i read something about improved mapping?

Unlikely it’s noticeable, although there have been some changes to Argyll CMS in that regard.
