LarryInRI, so you don´t wanna answer to my questions about your method of calibration where you loose a lot of overall contrast and power of light?
I don´t wonder why someones complaining about dark picture...
If you do things right it´s not dark, it´s only calibrated with balanced grey scale and natural color temperature.
Maby there is someone else who have X1 and calorimeter?
Just a little comparing while we have same model of calorimeter.
My´n blacklevel is not yet dropped, but you can get point what I´m talking about.
Black level drop should not affect higher % of gray, just 0 IRE.
LarryInRI, model 50X1, average gamma 2.12, Contrast 1273:1
0 IRE = 0.019 ftL / 0.07 cd/m2
10 IRE = 0.190 ftL / 0.65 cd/m2
20 IRE = 0.809 ftL / 2.77 cd/m2
30 IRE = 1.847 ftL / 6.33 cd/m2
40 IRE = 3.417 ftL / 11.71 cd/m2
50 IRE = 5.527 ftL / 18.93 cd/m2
60 IRE = 8.110 ftL / 27.79 cd/m2
70 IRE = 11.302 ftL / 38.72 cd/m2
80 IRE = 15.178 ftL / 52 cd/m2
90 IRE = 19.706 ftL / 67.51 cd/m2
100 IRE = 24.241 ftL / 83.05 cd/m2
Make73, model 50C10, average gamma 2.01, Contrast 6034:1
0 IRE = 0.008 ftL / 0.03 cd/m2
10 IRE = 0.458 ftL / 1.57 cd/m2
20 IRE = 1.822 ftL / 6.24 cd/m2
30 IRE = 4.032 ftL / 13.81 cd/m2
40 IRE = 7.276 ftL / 24.93 cd/m2
50 IRE = 11.609 ftL / 39.77 cd/m2
60 IRE = 16.417 ftL / 56.24 cd/m2
70 IRE = 22.378 ftL / 76.67 cd/m2
80 IRE = 29.009 ftL / 99,38 cd/m2
90 IRE = 37.265 ftL / 127.67 cd/m2
100 IRE = 45.908 ftL / 157.28 cd/m2
ftL = Foot Lambert
cd/m2 = Candela Per Square Meter
Difference is something like half less/more power of light.
When we´re talking about adjustments in service menu it´s easier to understand when you think that DRV is contrast of color and CUT is brightness of color.
Like in user menu adjusting brightness have more effect than adjusting contrast.
That´s why we start by adjusting 80IRE at first with DRV settings.
And one more time, it´s not a bad thing to always measure whole grey scale after doing adjustments in service menu, in that way you can notice how those changes affects also to lower IRE´s.
It takes more time, but maby results are also better than just measuring with 80% and 30% of luminence patterns.
Of course you should do basic settings in user menu before calibration.
If green is higher than red and blue it may be only option to lower G-DRV because there´s not so much you can raise R-DRV, however that was in my case.
Read from somewhere that you should not adjust DRV´s to FF because that´s maximum value and may cause damage to panel.
