For HDMI 2, the noise reduction level can be set between 0 and +3.

The default is level 0. When user increases the level, the player adjusts

the picture quality by applying mosquito noise reduction, random noise

reduction and MPEG block noise reduction at the same time. The higher

level user sets, the more aggressive noise reduction functions apply.

Colour Enhancement (HDMI 1 video output only) – Used to select a

colour enhancement level (enhance certain colours in the spectrum) of

the video output. It provides the ability to make more vivid some colours

without causing hue shifts, loss of details or changes in skin tones.

Contrast Enhancement (HDMI 1 video output only) – Used to select a

colour enhancement level (expands details in the shadows) on the video

output.

2. Dual HDMI Output

Allows you to select the output mode when both HDMI Output ports are

in use. If only one HDMI Output is active, this selection will not apply.

The options are:

Split A/V (Recommended) – Use HDMI 1 Out as the dedicated video

output port and HDMI 2 Out as the dedicated audio output port. This

setting will ensure the best possible picture quality and the highest

possible audio resolution.

Dual Display – Send digital audio and video signals to both HDMI

Outputs simultaneously. This setting is only recommended when two

HDMI displays are required, since the surround sound audio signal may

be down-mixed to stereo and the original audio quality may be lost.

Note: The player can automatically adjust the resolution of digital audio

and video signals depending on the capabilities of the connected

television and receivers. For HDMI 1 Out, the dedicated QDEO video

processor will be used unless Source Direct is selected, in which case

QDEO is bypassed.

3. 3D Output

To choose the video output mode for available 3D content at the HDMI

output ports. The options are:

Auto – Output 3D if supported both by the disc content and the display.

The player automatically checks for the existence of 3D content on the

disc and the 3D compatibility of the TV or projector. If both are qualied,

the player sends 3D video from its HDMI output terminals, otherwise only

2D video is sent out. 3D-compatible glasses are required compatible

with your TV.

Off – Always output 2D video format, even when 3D video exists on the

disc. This can guarantee the video quality in case that your TV is not 3D

compatible, or some necessary part (such as the 3D glasses) is missing.

Forced – Always output 3D video format for 3D Blu-ray discs. You

might experience a black screen (no video output) if your TV is not 3D

compatible.

4. 3D Setting

Adjusts the playback settings for better 3D visual quality.

Blank HDMI 2 – This allows the 752BD to force HDMI 2 to output a 2D

blank screen when HDMI 1 outputs 3D video.

2D->3D Depth – Adjusts the 3D depth perception when performing

2D-to-3D conversion (also called "simulated 3D"). The default value is 8.

3D TV Size

– To enter the diagonal screen size of your HDTV. This option

applies to 3D mode only, to facilitate the player adjusts the 3D image

for better visual quality. The diagonal size of your TV screen, by default

it is 46 inches.

5. TV Aspect Ratio

To set the aspect ratio of the player’s output image. The options are:

16:9 Wide – Choose this when the display is widescreen 16:9. 16:9

materials will be displayed in its native aspect ratio, and 4:3 materials

will be stretched horizontally.

16:9 Wide/Auto – Choose this when the display is widescreen 16:9.

16:9 materials will be displayed in its native aspect ratio, and 4:3

materials will be displayed with black borders on both sides in order to

maintain the original 4:3 aspect ratio.

You can continue adjusting the current parameter by pressing the /

buttons. To select another parameter, press the / buttons. Press the

Enter button to return to the large Picture Adjustment menu.

To exit the Picture Adjustment menu and return to the Setup Menu,

either select

"Exit" or press the Return button.

The following picture adjustment controls are available, for HDMI1 and

HDMI2:

Picture Mode – The 752BD allows you to save up to three (3) customized

video modes.

Press the / buttons to switch the mode and all parameters will be

automatically adjusted to their stored values. Changes to the current

parameter values will be stored automatically when you exit the Picture

Adjustment screen or, switch to another Picture Mode.

Brightness – To adjust the brightness (black level) of the video output.

Contrast – To adjust the contrast (white level) of the video output.

Note: Proper brightness and contrast settings are necessary for a quality

video output. If you do not have the correct black and white levels, your

images can appear washed out or can lose detail in shadows when

watching darker scenes. Televisions have brightness (black level) and

contrast (white level) controls; however it may require a combination of

tweaking both the player and your television to get the optimal result.

First adjust the television’s picture controls for the best possible picture.

Once that is done, try changing the player’s settings to further rene the

picture to the optimal result.

Hue – To adjust the hue (tint) of the video output.

Saturation –To adjust the saturation (colour intensity level) of the video

output.

Sharpness – To set the sharpness of the video output (Detail/Edge

Enhancement), this a video processing function that can control the

image sharpness but if overdone may cause unwanted artifacts.

For HDMI 1, the sophisticated QDEO video scaler is used sharpness level

can be set between -16 and +16. The default is level 0, which turns off

sharpness enhancement. The negative levels may be used to reduce

or eliminate overly sharpened video, the picture being progressively

softened.

The positive levels increase the sharpness. At level 1, the player applies

low level Detail Enhancement, during which the video processor isolates

the detailed parts from the original image, processes them separately and

integrates back before the nal output. At level 2, the player increases

Detail Enhancement to a higher level. Generally, to make an image

"sharper", we recommend using level 1 and 2. At level 3 and above,

the player adds Luminance Transition Improvement (LTI) and Chroma

Transition Improvement (CTI), which further sharpen the luminance

transition and chroma transition. However, we do not recommend using

level 3 and above unless the source content is from a poor source.

For HDMI 2, the Mediatek chipsets in-built scaler is used and sharpness

level can be set between 0 and +2. The default is level 0. The higher the

level, the sharper the video details are. However, too high a sharpness

level may cause white line etching around objects.

Noise Reduction – To select whether the player shall apply video noise

reduction processing.

For HDMI 1, the noise reduction level can be set between 0 and 8. The

default is level 0, which turns off noise reduction. When set to level

1, the QDEO scaler adjusts the picture quality by reducing "mosquito

noise" (artifacts around the outlines of objects) and "block noise"

(mosaic-like patterns caused by video compression). These two noise

reduction are also called Compression Artifacts Reduction (CAR) and

have several levels of aggressiveness. When set to level 2, the player

applies the Motion Adaptive Video Noise Reduction (VNR), which handles

the random noise and the lm-grain noise (natural variation of picture

intensity caused by lm grain).

Its level is automatic because there is a noise estimator circuitry in the

video processor that calculates how much noise presents and adjusts

the level of VNR accordingly. When set to a high level between 3 and

4, the player applies both CAR and Motion Adaptive VNR, with more

aggressive "block noise" reduction at level 4. At level 5, the player applies

aggressive CAR for low quality video content, and adds Motion Adaptive

VNR at level 6. At level 7, the player applies the most aggressive CAR

for very low quality video, and adds Motion Adaptive VNR at level 8.

Remember that excessive noise reduction may cause a loss of detail. We

recommend using the noise reduction function only when you encounter

poorly encoded or compressed video that has apparent noise artifacts.
