1.2 Assembly of a Raspberry Pi
If you wish to operate the display with a Raspberry Pi, you can use the mounng plaorm provided for
this purpose.
Remove the supplied mounng plaorm and aach your Raspberry Pi to it.
For a current Raspberry Pi, use the screw holes number 6.
A list of the provided screw holes for all common microcontrollers can also be found on the mounng
plaorm.
Aer you have mounted your Raspberry Pi, place the mounng plaorm on the back of the display and
mount it (screw holes 9-Vesa).
The display is now completely assembled and should correspond to the following picture.

1.3 Connecting to a device
First connect the display to the enclosed power supply. Next, connect the HDMI cable to the display and

In order to be able to use the touch funcons, the USB cable must also be connected to the display and
the device to be used.
Aenon! Do not mistake the USB ports. To be able to use the touch funcons, the USB port
with the inscripon "Touch" must be used on the display.

2.2 Manual installation & calibration
If you do not want to install our prepared image or integrate the display into an exisng system, you can
of course also install the display manually.
To ensure that the image is displayed correctly when the display is switched on with the Raspberry Pi, the
"cong.txt" le must rst be edited. Open it with the following command:
2. USE OF THE DISPLAY
Aenon! If you start the display for the rst me, the Raspberry Pi must be started aer the
display, otherwise the image transmission will not work.
sudo nano /boot/config.txt
 Use with one, Raspberry Pi 4:
For use with a Raspberry Pi 4, a seng in "/boot/cong.txt" must be edited. Enter the following com-
mand:
Under point [pi4] you have to comment out the command dtoverlay = vc4-ms-v3d, this should look like
this:
[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
#
#dtoverlay=vc4-fkms-v3d <---- This setting must be commented out with a #
max_framebuffers=2
sudo nano /boot/config.txt

Now install the touch screen drivers with the following command:
To ensure that the installed drivers are always inialized aer the exisng drivers, copy the conguraon
le with the following command:
Next, the calibraon tool can be installed and started with the following commands:
Restart your Raspberry Pi:
Before you can start the calibraon tool, you have to create the le for the calibraon sengs:
Enter the following sengs in this le:
Restart your Raspberry Pi:
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=27
sudo apt-get install xserver-xorg-input-evdev
sudo cp /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
sudo apt-get install xinput-calibrator
sudo reboot
sudo nano /usr/share/X11/xorg.conf.d/99-calibration.conf

calibraon values, which you must enter in the previously created le "99-calibraon.conf".
Enter the following command:
Enter the following content here and add the four values of the "Calibraon" opon with those that were
output to you in the previous step:
Now you need to restart your Raspberr Pi for the last me:
Now the touch funcon is ready to use.
sudo nano /usr/share/X11/xorg.conf.d/99-calibration.conf

2.3 Using with a Windows-PC
Connect the display with the supplied power cable. Now connect your computer and the display with an
HDMI or VGA cable, depending on your preference.
You can also connect your computer to the touch interface using a USB cable if touch screen operaon is
desired. However, this requires an addional driver installaon.
The drivers for the touch funcon can be found on this website.
In order to ensure the touch funcon of the display even when using several screens, the mulple monitor
funcon must be acvated in the eGalax Touch program.
To do this, rst open the program:
You must then select the Display tab:
Aenon! On some systems it may happen that the latest drivers are not fully funconal. In this
case beer results can be achieved with an older driver. You can download an older driver here.
