Advanced picture settings 

The 

Advanced picture settings

 menu for each TV input provides settings for fine tuning the appearance of the picture. All of 

the settings in this menu apply only to the currently-selected input.
To use the 

Advanced picture settings

 menu, first press 

[   ]

 to display the 

Options

 menu. Then select 

Advanced picture 

settings

.

To adjust the settings on the 

Advanced picture settings

 menu, press 

[UP]

 or 

[DOWN]

 to highlight a setting, and then press 

[LEFT]

 or 

[RIGHT]

 to change the setting. You’ll notice the changes you make right away in picture appearance.

Tip:

 When you highlight a setting, the header text explains the effect of its current value. When you begin to adjust a setting, 

the other options are hidden so you can see more of the screen. Even though the other settings are hidden, you can move 
the highlight up or down to adjust the other settings. As soon as you press 

[UP]

 or 

[DOWN]

, the other settings become visible 

again

Advanced picture settings menu options

 

Picture mode

 – Provides picture presets for various viewing preferences. This setting duplicates the one on the 

Options 

menu. When you change the 

Picture mode

, other picture settings adjust accordingly. For example, setting the 

Picture 

mode 

to 

Vivid

 sets 

Brightness

Contrast

Sharpness

, and other values to produce a very vibrant picture. Setting 

Picture 

mode

 to 

Movie

 changes these same settings to produce a picture suitable for enjoying movies in a darkened room. If you 

make changes to the individual picture settings—for example, 

Contrast

, or 

Sharpness

—these settings are saved for the 

current input and the current picture mode. In this way, the HDMI 1 input’s 

Movie

 picture mode can be different than the 

HDMI 2 input’s 

Movie

 picture mode and Antenna TV’s 

Movie

 picture mode. Use 

Reset picture settings

, described below, 

to return the input’s current picture mode to its original values.

 

Dynamic Contrast

 - 

Only on select models:

 

Automatically adjusts the backlight level to achieve the optimum contrast and 

prevent excessive differences between light and dark areas of the screen.

 

Backlight

 - Adjusts the overall brightness of the screen.

 

Brightness

 – Adjusts the dark level of the black areas of the picture.

 

Contrast

 – Adjusts the white level of the light areas of the picture.

 

Sharpness

 – Adjusts the sharpness of the edges of objects in the picture.

 

Color

 – Adjusts the intensity of colors in the picture. A setting of 0 removes all color and displays a black and white picture.

 

Tint

 – Adjusts the color balance from green to red to obtain accurate colors in the picture.

 

Color temperature

 – Adjusts the overall colors in the picture from 

Normal

 to slightly more bluish (

Cool

) to slightly more 

reddish (

Warm

).

 

Game mode

 – Controls whether ‘Game’ mode is on or off. When 

On

, the TV performs less image processing and has less 

input lag. When 

Off

, the TV performs more image processing and has more input lag, which is less desirable for action 

games. 

Available only for HDMI inputs.

 

Reset picture settings

 – Returns all picture settings for the input’s currently-selected 

Picture mode

 to their original values.

Tip:

 To dismiss the 

Advanced picture settings

 menu, just wait a few seconds without pressing any buttons; or, press 

[   ]

again to dismiss the menu immediately.
