1. Precautions and safety instructions

• Please read this guide carefully before using the product and keep it scrupulous.
• Transport the display with at least two people.
• Place the display only on a stable, flat surface, paying attention to the infrared receiver on the underside of the device.
• If the device is brought from a cold to a warm environment, condensate can form inside. In such a case, the product should not be moved for a period of at least 24 hours before restarting, so that the condensate can dry in the air.
• No liquids or metallic objects must enter the product. If this is the case, immediately unplug the power plug and contact the service.
• Do not wipe with solvents such as gasoline, acids, alkalis, sharp or abrasive detergents, volatile oils and diluents, as these solvents can damage the product.
• Do not apply force when wipering the display, as this can scratch the display.
• Do not operate the display in direct sunlight.
• The ventilation openings must not be concealed.
• It is enclosed with a 3-pin power cable. Before installing, make sure that the grounding connector of the socket is properly grounded. Do not lay the power cable in passageways so that no people step on it; also keep it away from the areas where it could be squeezed.
• If the display is not in use for an extended period of time, turn it off and unplug the power plug.
• In case of unusual noises or smells, please turn it off immediately and unplug the power plug. Stop using it if necessary and contact the service.
• Do not try to open or disassemble this product, as this will expose you to dangerous tension or other risks.
• Avoid that static content, text or icons remain on the screen for too long, as this will lead to a "ghosting" on the screen.

5. Remote control

5.1 Functions of the buttons

5.2 Notes on the use of the remote control

• Point the remote control at the receiver. Objects located between the remote control and the radio receiver can interfere with the function.
• Replace the batteries if they are low, as the range of the remote control will be reduced.
• If the remote control is not used for a long period of time or the batteries are dead, please remove the batteries, as liquid leakage from the batteries may cause damage to the remote control.
• Do not use different types of batteries and do not combine new batteries with those that have already been used. Always replace batteries in pairs.
• Please dispose of empty batteries in accordance with the respective environmental regulations.

5.3 Choice of sources

The 3 button calls up the source menu. Using the navigation keys (up/down), the source is selected and confirmed with OK.

6. Settings

6.1 Accessing Settings

To access the menu, you can either press button 4 on the remote control or swipe inwards from the left or right edge of the screen. This will make the two icons visible at the edge of the screen. To access the menu, tap on one of the two.

6.1.1 Home | Status

Source: Select the desired input source.

Volume: Use the slider to adjust the volume.

Brightness: Use the slider to manually set the brightness of the display's backlight.
Alternatively, you can dynamically adjust the brightness to the ambient brightness by activating automatic brightness control.

hint: The manual control and is only possible if the automatic function is deactivated.

6.1.2 Display

Picture Mode: There are different ideas to choose from, adjust the color representation, the contrast.
The "User" selection allows you to manually adjust and adjust brightness, contrast, saturation and sharpness.

Colour temperature: Increases or decreases the red or blue portion of the display. You can choose between Medium (balanced), Cool (increased blue content) and Warm (increased red component)

Aspect ratio: As a rule, the input electronics of the display recognize the aspect ratio of the video signal itself and display it accordingly correctly.
You can use the 16:9 or 4:3 selection to make adjustments manually if necessary.
P2P Picture to Picture: The image is displayed in the transmitted original resolution centered in a part of the display.

hint: The display's native aspect ratio is 16:9.

6.1.3 Settings

Under Settings, you can descend into three submenus.

Language:
Select the language in which you want the menu and status messages to be displayed.

Entrance:
In this area, you can make basic settings:

Boot Source: The selection determines which input source is automatically selected after the display is started.

EDID Setting:
Here you determine which EDID information is stored on the HDMI and USB-C inputs and is transmitted to the source.

EDID 2.0 = 3840 x 2160 at 60 Hz and full color resolution (4:4:4)
EDID 1.4 = 3840 x 2160 at 30 Hz or 60 Hz with reduced color resolution (4:2:0).

hint: The EDID information coordinates the source and display. The higher the resolution and refresh rate, the more demanding the signal transmission, which becomes a challenge, especially at longer distances. The EDID 1.4 setting can help solve the problem in these cases.

Automatic Source Selection:
If this option is activated, the display automatically switches to the last plugged-in source.

CEC Control:
If this option is activated, the display can control connected devices via CEC command, e.g. turn a soundbar on and off.

Hint: CEC (Consumer Electronics Control) only works via HDMI and with compatible devices.

Standby without signal:
If there is no signal, the display can be automatically switched to standby after 10, 30 or 60 minutes. Alternatively, this function can also be deactivated, please select "Off".

Info:
Here you will find relevant information that is important in the event of support, especially the firmware version.

hint: The serial number cannot be displayed in the menu for technical reasons. You can find them on the side of the left edge of the display or on the back of the nameplate.

The images shown on the product are disturbed by dotted lines or stripes (in the case of HDMI or DP signals).	Poor transmission quality	Shorten the cable length, reduce the number of connectors, or reduce the resolution or refresh rate. Alternatively, a signal repeater can help.
Remote control only works from a short distance or not at all.	> The receiver of the display is blocked by another object. >The battery of the remote control is low. >The use of the remote control has been deactivated.	> Remove the item before the recipient. >Replace the batteries.
Touch operation is slow, doesn't work (Android).	There are too many programs running.	Close the programs that you do not need and thus free up memory.
OPS cannot be activated, no display, no touch operation.	OPS was not used properly.	Re-insert the OPS. To do this, make the display powerless.
The touch function does not work with externally connected computers.	> The USB cable is connected to a USB port that is not associated with the video source. > The touch USB cable is too long or of poor quality.	> Check and change the corresponding interface of the touch USB cable. > Use a shorter or shorter active USB cable.
