How to Calibrate a TV with a SMARTPHONE (FOR FREE!!!)

Essentially, after setting the contrast and brightness values, I have to calibrate the color level to enter equal values of the colors that make up the entire color range of the TV. That is, the perfect boom is for both the low point and the highest balanced balance of the three colors.
Example: high point - R (red) 187, G (green) 214, B (blue) 211. It is perfect that these values are in balance. RGB 211,211,211, this value may change but the numbers must be at the same level.

This movie shows you how you can calibrate your TV's colors using your mobile phone and an app from Google Store.


The application name is COLOR GRAB and is free in the store.

After installing the application, you must enter the CAMERA (bottom left) and after up to the right in the settings to select CAMERA LETF CELL RGB. After that you have to find a way to suspend the phone in front of the TV or keep it in your hand, but it is tedious.
You can keep it 1-4 inches from the TV screen.

For calibration, you need 2 patterns, one for the low point (30% gray) and one for the high point (80% gray).
You can easily find them on the internet, or if you can not find them, write to me and I'll send them to you.

For starters, you have to find your TV set after you have set the brightness settings (you can find them on the Internet depending on your TV model or you can calibrate them as you like) the setting for Expert Controls (note these settings are available at LG only in Cinema, Expert Room Dark and Bright, at Samsung are just in CINEMA ... at other brands I do not know exactly where you can find them, you can not access them at Sony).

Once you have identified where to enter the menu, you must set the whitish of white as close as possible to the natal sunshine at noon, which is 5000-6500 k. This setting translates to Color Temperature warm 2 (to LG and Samsung), the other brands do not know how they are past.

VERY IMPORTANT IF YOU HAVE IN THE MENU-COLOR GAMUT, PLEASE GO ON NORMALLY. Do not confuse color gamut gamma whit gamma.
