Default the truth about gamma

well gamma is a big problem for our gpad, anyone know.

resuming...
4.2.2 v50010a gamma 1.6 - 1.8
4.2.2 v50010b gamma 2.0 - 2.1
4.4.2 v50018a gamma 2.2 - 2.4
4.4.2 v50020a gamma 2.0 - 2.1 AGAIN!

apparently v50018a is the best but checking with display tester not only the gamma but also the black and white saturation test... surprise!
the level of black and withe is the same!
i also compared gpad with my other tablet: asus memo pad hd 7 that have a much clear display and a gamma 2.2 - 2.4.
comparison side by side with display tester and a brightness comparable with 100% for gpad and 85% for asus:
asus go deep in black and white saturation test with more "seeable" blocks.
gpad: black 7 - white 250
asus: black 2 - white 254

only solution is the app "screen adjuster", with a contrast of -30 for gpad i have same results of asus in black and white saturation test.

I am just sticking with 18a as in my sig. Aside from the lack of QVoice, everything works and is fine.

At 100% brightness the g pad does great. It's less than 50% is where It fails. Custom kernels for 4.2.2 fixes that problem (video watching). When we get the source from LG for 4.4.2 it will be fixed by the community again.

Honestly id be happy with any gamma if i could see 0-255. I swear its set for video levels and you can only see 10-245 ish before its all washed out.


Still ive seen alot worse. At least pictures dont look washed out and blacks dont look grey.
