[Nexus 10 General] Patrik G:
Here is the Nexus 10 Pre Calibration Results.

no post calibration due to lack of adjustments right now,so its not much to do than accept it.

i try to explain the results here

first Gamma: average 2.21

that is reference class but the problem here is that the line isnt flat.

it should be straight at 2.2

around 2.0 at the darks and 2.4 in the whites

that isnt that bad that i thought it should be

i was more into that the gamma was way lower, around 1.5

if everyone complains about washed out blacks then they are close to reference.

so stop crying and enjoy details in the dark scenes ;)

i think most other OLED screens have much higher gamma for the darks just to get a fake contrast boost.

the problem then is that you loose details in dark scenes and get crushed blacks.

on the Nexus 10 we dont loose any details.

Next Color temp: 6784 Kelvin is great.

6500 is reference so its just a little bit to the blue side

GrayScale: thats the one that makes white where it should be white

i must say that the grayscale is reference!

Great work Samsung!

the only part that sails away is IRE10 that has to much blue and red in it but then IRE 10 is almost black and you

will not see the colors.

Contrast

Blacklevel is great at 25% brightness on the Nexsus 10

with that brightness(Y: 130= recommended brightness for LCD TVs) you get a contrast ratio of 814:1

average i must say but not bad

with higher brightness you loose blacklevel.

(i also measured the Contrast ratio at 50% brightness and its the same around 800:1

blacklevel at 50% brightness is higher Y: 0.300)

and so to the worst

Color Inaccuracy!

Bad Bad Work Samsung

the calibrator must have slept during the process

not much to say that blue isnt blue on the Nexus 10

165%!! to high brightness and to low saturation

the only colors that is close to reference is CYAN followed by YELLOW and RED.

the others has to low saturation.

Note: the White Dot in the middle is our Whites

and with the reference class grayscale that dot is almost in the box.

its the white dot that controls all other colors so if that is off all colors is off.

but that doenst make any sense here.

the colors should be better but they are not.

i think the main problem here is the Colour Gamut itself.

samsung have choosen the wrong colour gamut for the Nexus 10.

so the conclusion is that Gamma level isnt as bad as everyone thought

the bad thing here is the colors with its low saturation and wrong brightness.

A new "Wider" colour gamut can make this display world class.

Edit: to the Developers that searching for a gamma adjustment you can stop doing that :)

The Gamma Curve isnt the main problem.

if we are lucky samsung has several different colour gamuts hidden somewhere.

so thats what you should look for.

on my LED tv i have 5 different colour gamuts to choose from and they all get different CIE scores.

if there are several Gamuts hidden they should be named "Wide" "Standard" "EBU" "SMPTE" "BT709"

Edit2: or you could search for "Adobe RGB"

thats one gamut that should have been on the Nexus 10 from start.

Nexus 10 cant even use the full sRGB colorspace,we only get 75% of sRGB it and that is really bad.

i was just checking the colors on my Galaxy S2 and it uses the full Adobe RGB colors.

thats why all colors looks so vivid on most OLED screens

they are calibrated to the wider Adobe RGB Gamut.

info on all colorspaces used:

you can see that you get way more colors with the Adobe RGB compared to the standard sRGB
