3.1.1 Input Settings
The DIMAX404 handles four input channels while the DIMAX804 handles 8 input channels.
Each channel’s input properties can be modified individually.
Selecting the input channel (1 - 4) will guide the user into the specified input menu. In this
submenu all of the settings belong to the selected input, so you can set different input setting
parameters for each input types. It contains:

The colour capabilities of different inputs may differ from each other. Therefore, the set of
adjustable parameters can differ for each of the source types.
Brightness, Contrast, Hue, Saturation and Sharpness controls can adjust the colour
properties of the inserted video image.
• Brightness determines the black level of the video signal. Small values result in a
dimmer image while large values produce a brighter image.
• Contrast determines the dynamic range of information present in the video image. Small
values result in an image of constant colour and intensity while large values produce
more contrast.
• Hue shifts the phase of the video’s colour information relative to its reference, causing a
shift in colour. A middle value results in no shift, negative values shift red towards green
and positive values shift red toward blue.
• Saturation is the colour information present in the video image. Small values result in
black and white image while large values provide increased amount of colours.
• Sharpness determines the sharpness of the input signal. Small values result in blurred
image.
Reset all
By a simple press you may reset these parameters to their default value.

Audio Input
The Audio Input helps to select the right input and output audio handling method. (Analogue,
Embedded <HDMI, Display Port>)
OverScan
The OverScan is an extra image cropping area around the video image. The OverScan is
available for analogue inputs only and can be set in three values (Off, Medium, Full).
HDMI EQ
In case of HDMI/DVI input HDMI Equalizer settings can be modified. This feature can stabilize
the HDMI connection with our product and can be set between two values (Low, High).
3.1.2 Output Settings
Individual or common output parameters can be set in this menu item. Commonly adjustable
parameters are:
• Output Timing
• Output Mode
• HDCP Enable
• Output Enable.
The EDID Expert parameter is adjustable individually, because the EDID information can be
different for each display. All the output parameters can be set separately for each display.

There is a special function:
• Recommended
The device checks the native resolution of the screen and sets the most suitable output
resolution for the screen.
Output Mode
In HDMI mode audio packets, control packets and info frame packets are sent within blanking
period of signal. HDMI compliant receivers can accept them, but receivers designed to receive
pure DVI signals may be disturbed. The Output Mode has three options:
• In case of Auto Mode the output mode depends on EDID information read from the
display.
• In case of Force HDMI mode the device will generate audio packets, control packets
and info frame packets independent from the EDID information of the display.
• In case of Force DVI mode the device skips these special packets.
HDCP Enable for Output
The user can turn on or turn off the HDCP authentication process for the output.

DEXON Systems
Output Enable
The user can turn on or turn off the output’s input image insertion.
EDID Expert
The DIMAX404 provides EDID information to DVI, RGB and DisplayPort input sources. This
makes sure to have correct and native input source resolution. The position of the menu tree
determines the source of the EDID information.

Transition Effects
The DIMAX404 contains multiple switching effects:
• Cut – Seamless switching between two inputs (no blank frame between switching)
• Fade – Previous input fades out as the next fades in
• Horizontal Wipe – The next input wipes across the screen
• Vertical Wipe -
ADC Calibration
There is a special circuitry for the right decoding of the colours of certain analogue inputs.
• ADC Calib.All function provides internal reference calibration for all analogue inputs.
• ADC Calib. Input and Pixel Grab functions require special input signals.
Signal required for specific input type:
Input type Method Used Signal Source Pattern
Composite One CVBS input none
YUV-Component Pixel grab Colour 8 bar 100%
Colour 8 bar 75%
RGB Pixel grab Colour 8 bar 100%
Auto Adjust
This function is available only, if RGB input is selected.
Auto Adjust is used for IBD (Image Boundary Detect) and phase detection. This process implies
a very complex image detection to acquire perfect image parameters.
LCD Display
The LCD panel’s turn off time can be set in this menu item. The default value is 10 seconds.
LCD brightness can be modified also.
Remote Control
This menu item contains the parameters of remote control, which are the IP address and
network mask. Initial IP address: 192.168.1.105 (network mask: 255.255.255.0). You should
press the SET button to save the settings, then select Apply now to make the settings valid.
Self-Test
The Self-Test is an embedded test sequence checking all input signals and setting output
resolution in a sequence.
When this function is selected, the device checks all the possible inputs in a predefined order
and displays their content at 1024x768@60Hz timing for 10 seconds. Then, it changes to
1280x720@60Hz and starts checking the input signals again. Finally, it switches to

DIMAX404 User’s Manual

1920x1080@60Hz and checks all the inputs again. When this test sequence is finished, the unit
automatically starts a new test loop.
Factory Reset
The factory reset is a full restore of device to its factory settings.
3.1.4 Layouts
Use this menu to save the current and recall previous layout. You may save 8 sets of
parameters. You can use the push buttons (P1-P8) to select from the Layouts only if you are not
navigating in the main menu.
