Working with PC

This LCD can support Windows 7 /8 /8.1 /10 /11 system.

1) Turn on the backlight switch on the back of the LCD.

2) Connect the Touch interface of the LCD to the USB interface of the PC. Wait for a while, the windows will automatically recognize the touch function.

3) Connect the HDMI interface of the LCD to the HDMI interface of the PC.

Normally you can see an interface similar to the following figure. (Some PCs may need to be restarted to display.)

Calibration touch on Win 10 PC

Take the windows10 system as an example:

1. Enter the Windows settings of the system, type in the search bar, and click "Calibrate the screen for pen or touch input" (as shown in the picture below).

2. Click "Setup" in the pop-up "Tablet PC Settings" interface:
3. The following text prompt will appear on the screen. Please tap the touch screen with your finger, and the computer will recognize it as a touch screen.

【Note】If the touch screen is blank, press the "Enter" key, and the text prompt will switch to the touch screen. (The screen which displays the text prompt will be used as a touch screen!)

Working with Raspberry Pi

This LCD can support Raspberry Pi OS / Ubuntu / Kali / Retropie systems. When the LCD works on systems such as Raspberry Pi, the resolution must be set manually, otherwise, it will cause an abnormal display. There is no such problem when the LCD works on the PC version of Windows.

Please download the latest version of the image from the Raspberry Pi official website.

1. Download the compressed file to the PC, and extract the img file. 2. Connect the TF card to the PC and use SDFormatter to format the TF card. 3. Open the Win32DiskImager software, select the system image prepared in step 1, and click write to burn the system image. 4. After the programming is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt, and save it.

hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1

You must ensure that there are no spaces around the equal sign. 5. Insert the TF card into the Raspberry Pi and turn on the backlight switch on the back of the LCD. 6. Connect the Touch port of the LCD to the USB port of the Raspberry Pi. 7. Connect the HDMI port of the LCD to the HDMI port of the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds to display normally.

Calibration in Raspbian

Install related software:

sudo apt-get install xinput-calibrator
sudo apt-get install xserver-xorg-input-evdev
sudo cp -rf /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
sudo reboot

There will be an additional Calibrate Touchscreen in Menu->Preferences, run the demo to calibrate.
Perform touch calibration according to the displayed prompt. After calibration, there should be a good touch effect (if the error is relatively large, you can re-run the calibration procedure).
If you want to save these touch values, you need to create a new 99-calibration.conf file in the following path:

/etc/X11/xorg.conf.d/99-calibration.conf

Save information similar to the following to 99-calibration.conf.

After running, you can touch and long press to realize the right-click function.

Set IP

sudo usermod -G 'input' -a pi
echo 'uinput' | sudo tee -a /etc/modules
sudo nano  /etc/udev/rules.d/99-uinput.rules

Add in 99-uinput.rules file.

KERNEL=="uinput", MODE="0660", GROUP="input"

save it and run it in the terminal.

sudo udevadm control --reload-rules
sudo udevadm trigger

Then reboot:

sudo reboot

Run after reboot (no sudo needed at this point)

Do I need an external power supply when I use a 5-inch HDMI LCD (B) connect to Raspberry Pi?

When the Raspberry Pi is powered by a 5V 2A power adapter and connects to 5-inch HDMI LCD (H), it doesn’t require an external power supply by default. However, if the user uses the Raspberry Pi to drive other high-power devices at the same time, the USB interface on the Raspberry Pi may be insufficiently powered, at this time an external power supply is required.

How to use the touch function when connected to a Linux PC that is non-designated?

You can try to compile the universal touch driver "hid-multitouch" into the kernel, which generally can make the touch function work.

What can I do if the thin red lines appear on the edge of the screen?

Edit the config.txt and add this line at the end of the config.txt file:

hdmi_drive=1

What is the consumption of 5inch HDMI LCD (B)?

With 5V power input, the working current is about 385mA when the backlight is on, and 195mA when the backlight is off.

Can the brightness of 5-inch HDMI LCD (B) be adjusted by modifying the resistance?

The screen brightness can be changed by modifying the resistance of the resistor in the figure below, the default resistance is 2.7 ohms.

What is the refresh rate of this screen?

60Hz.

Does the screen not automatically rest, or do I have to execute a command to rest the screen?

It depends on the system, if the system has hibernation, the screen will also be black. If it is the official system of Raspberry Pi, the default is about ten minutes without action to have hibernation.
