5. Setup Instructions

5.1. Connecting to Raspberry Pi (Raspbian/Ubuntu Mate/Win10 IoT Core)

Follow these steps to set up your display with a Raspberry Pi:

1. **Install Raspbian Official Image:**
   • Download the latest image from the official Raspberry Pi website.
   • Install the system according to the official tutorial steps provided by Raspberry Pi.
2. **Modify "config.txt":**

   After programming the Micro SD Card, open the `config.txt` file located in the root directory of the Micro SD Card. Add the following lines at the end of the file, then save and safely eject the Micro SD Card:

   max_usb_current=1
   hdmi_force_hotplug=1
   config_hdmi_boost=10
   hdmi_group=2
   hdmi_mode=87
   hdmi_cvt 1024 600 60 6 0 0 0

3. **Connect Hardware:**

   Insert the Micro SD Card into your Raspberry Pi. Connect the Raspberry Pi and the LCD using an HDMI cable. Connect one end of the USB cable to one of the four USB ports on the Raspberry Pi, and the other end to the USB port on the LCD. Finally, supply power to the Raspberry Pi. If both the display and touch functions work correctly, the setup is successful. Ensure a full 2A power supply for optimal performance.

5.2. Connecting as a PC Monitor

To use the display with a PC (Windows 7/8/10):

1. Connect the computer's HDMI output to the LCD's HDMI interface using an HDMI cable.
2. Connect the LCD's USB Touch interface (either of the two MicroUSB ports) to a USB port on your PC.
3. If you have multiple monitors connected to your PC, temporarily unplug other monitor connectors and use the LCD as the only monitor for initial testing to ensure proper detection and functionality.

6. Operating Instructions

6.1. Touch Functionality

The display features a 5-point capacitive touch screen, allowing for intuitive interaction similar to a smartphone or tablet. For Windows systems, it supports 5-point touch directly (Windows XP and older versions support single-point touch). For Raspberry Pi with Raspbian/Ubuntu/Kali-Linux/Kodi/Win10 IoT, it supports single-touch driver-free.

6.2. Adjusting Brightness and Sound

The display allows for adjustment of backlight brightness and sound. Refer to Video 1 (0:30 mark) for a demonstration of how to access and adjust these settings via the on-screen display (OSD) menu using the physical buttons or trackwheel on the side of the monitor.

6.3. Rotating Display Direction (Raspberry Pi)

To rotate the display orientation on your Raspberry Pi (e.g., for portrait mode):

1. Open the `config.txt` file located in `/boot/` directory:

   sudo nano /boot/config.txt

2. Add the following line at the end of the file. Replace `X` with the desired rotation angle (0: 0°, 1: 90°, 2: 180°, 3: 270°). Then, press `Ctrl+X` to exit and `Y` to save.

   display_rotate=X #0: 0; 1: 90; 2: 180; 3: 270

3. Restart the Raspberry Pi for changes to take effect:

   sudo reboot

6.4. Rotating Touch Direction (Raspberry Pi)

After rotating the display, the touch input may need to be re-calibrated to match the new orientation:

1. Install `libinput`:

   sudo apt-get install xserver-xorg-input-libinput

2. Create the `xorg.conf.d` directory in `/etc/X11/` if it doesn't already exist:

   sudo mkdir /etc/X11/xorg.conf.d

3. Copy the `40-libinput.conf` file to the newly created directory:

   sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/

4. Edit `/etc/X11/xorg.conf.d/40-libinput.conf`:

   sudo nano /etc/X11/xorg.conf.d/40-libinput.conf

   Find the section related to the touchscreen and add the appropriate `Option "CalibrationMatrix"` statement. Then, press `Ctrl+X` to exit and `Y` to save.

   • **0° Rotation:** Option "CalibrationMatrix" "1 0 0 0 1 0 0 0 1"
   • **90° Rotation:** Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
   • **180° Rotation:** Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"
   • **270° Rotation:** Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"
5. Restart your Raspberry Pi:

   sudo reboot

7. Troubleshooting (FAQ)

Q: How do I get the display to work initially?

A: First, connect the USB cable for power and touch. Once the display powers on, then connect the HDMI cable. This sequence helps ensure proper detection and initialization.

Q: Can I use this display with a standard computer?

A: Yes, it can be used with various computers including Raspberry Pi 3, Raspberry Pi 4, Raspberry Pi Zero W, and other mini PCs. For Windows PCs (Win7, Win8, Win10), it supports 5-point touch directly without additional drivers.

Q: The display is on, but the screen is blank or shows garbled text.

A: Ensure the HDMI cable is securely connected at both ends. For Raspberry Pi, verify that the config.txt modifications (especially hdmi_cvt and hdmi_mode) are correctly applied and match the display's native resolution (1024x600). For PC, ensure your computer's display settings are configured to output to the correct resolution for the external monitor.

Q: Touch input is not working or is inaccurate.

A: Ensure the USB cable is properly connected to both the display and the host device (Raspberry Pi or PC). For Raspberry Pi, if you rotated the display, you must also rotate the touch input as described in Section 6.4. For PC, ensure no other touch devices are interfering, and try recalibrating the touch screen through your operating system's settings.

8. User Tips

• **Power Supply:** Always ensure your Raspberry Pi or other host device is supplied with a stable and sufficient power source (e.g., a full 2A power supply for Raspberry Pi) to prevent display issues or instability.
• **Connection Order:** For best results, connect the USB cable (for power and touch) to the display first, then power on the device, and finally connect the HDMI cable.
• **Screen Protection:** While the display is durable, avoid applying excessive force to the screen. Use a soft, lint-free cloth for cleaning.
• **Optimal Viewing:** The IPS panel offers a 178° wide viewing angle, ensuring clear visuals from almost any perspective. Adjust the portable stand for your preferred viewing angle.
