*Notes: * t613 + tas5130A
|
|
* * Focus to light do not balance well as in win.
|
|
* Quality in win is not good, but its kinda better.
|
|
* * Fix some "extraneous bytes", most of apps will show the image anyway
|
|
* * Gamma table, is there, but its really doing something?
|
|
* * 7~8 Fps, its ok, max on win its 10.
