What's ON Board

7HP-CAPQLED-Exterior-Size.jpg

Working with PC

This product supports Windows 10/8.1/8/7 OS.:
1. Connect the TOUCH interface of LCD to the USB interface of PC. Wait for a while, the windows will automatically recognize the touch function.
2. Connect the HDMI interface of LCD to the HDMI port of PC. About 5s later, you can see the LCD display properly. If you need the audio, you can insert a 3.5mm earphones to HP ports.
Note:
1) When the computer is connected to several different displays at the same time, only this LCD can be used to control the cursor on the main display, so we recommended to set this LCD as the main display.
2) Some of PC cannot support HDMI screen Hot Plug. In this case, restart the PC can solve.
3) Sometimes LCD will flicker because of undersupplying from USB cable of PC. You need to connect an external power supply (5V/2A) to DC port.
4) HP audio output only works while using HDMI communication
5) Mini HDMI to VGA Cable is necessary and need to be purchased separately if you use VGA communication.

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)

Win10 touch011.png

  • 2. Click "Setup" in the pop-up "Tablet PC Settings" interface:

Win10 touch02.png


  • 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

Supports Raspbian/Ubuntu mate/Windows 10 IoT Core

When working with Raspberry Pi, you should set the resolution of the LCD by yourself, otherwise, the LCD screen will not work. For more detailed information, please read the following section.

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

1) Download the compressed file to the PC, and unzip it to get the .img file.

2) Connect the TF card to the PC, use SDFormatter.exe software to format the TF card.

3) Open the Win32DiskImager.exe software, select the system image downloaded in step 1, and click‘Write’ to write the system image.

4) After the image has finished writing, open the config.txt file in the root directory of the TF card, and comment out dtoverlay=vc4-fkms-V3D.

5) Add the following code at the end of config.txt, then save and quit the TF card safely.

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

You must make sure that there are no spaces on either side of the equal sign.

6) Save and connect the TF card to your Pi then power up.

7) Connect the Touch interface of LCD to the USB port of Raspberry Pi.

8) Connect the HDMI interface of LCD to the HDMI port of Raspberry Pi.


Note:

  • Resolution of Ubuntu Mate OS or Windows 10 IoT Core OS can also be set properly by editing config.txt.
  • For Pi Zero / Zero W: if you've used an SD card on a Pi 3 and then attached the card to the Pi Zero, the touch screen often doesn't work. In such cases, you have to write a fresh system image to the SD card. The first boot up must be done on the Pi Zero but not Pi 3, due to initialization for a corresponding device.

Rotation(Working with Raspberry Pi)

Display Rotating

Add this statement in the config.txt file (the config file is located in the root directory of the TF card, which is named /boot):

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

Note: For Raspberry Pi 4, you need to comment out dtoverlay=vc4-fkms-V3D.

#dtoverlay=vc4-fkms-V3D.

And then restart the Raspberry Pi after saving.

sudo reboot

Touch Rotating

After the display is rotated, the position of touch is incorrect because the touch doesn’t change with the display angle. So the touch also needs to be modified.

1.Install libinput.

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

If the system you installed is Ubuntu or Jetson Nano. The installation code is:

sudo apt install xserver-xorg-input-synaptics

2.Create the xorg.conf.d directory under /etc/X11/ (if the directory already exists, proceed directly to step 3).

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

3.Copy the 40-libinput-conf file to the directory you created just now.

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

4.Edit this file.

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

Find the part of the touchscreen, add the following statement inside, and then save the file.

Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

Similar to the picture below:

Touch roate.jpg
5. save and reboot your Pi

sudo reboot

After completing these steps. The LCD could rotate 90 degrees both display and touch function.

Note:

90 degree: Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

180 degree: Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"

270 degree: Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"

Backlight adjustment on Raspbian OS

  • 2. Enter the corresponding directory of this file in the terminal and run the command as follows:
 ./7HP_Backlight -b  X      # X range is 0~10, 0 is the darkest, 10 is the brightest

For example:

 ./7HP_Backlight -b  3

Working with Jetson Nano

To work with Jetson Nano Developer Kit, you don’t need to make software configuration.

1) Connect the TOUCH interface of the LCD to the USB interface of Jetson Nano.

2) Connect the HDMI interface of the LCD to the HDMI interface of the Jetson Nano and then power on the Jetson Nano. After about 5 seconds, you can see the LCD display normally. If you need to output sound, you can insert a 3.5mm earphones to the HP audio output interface.

Note:

1) If the LCD flickers, it may be due to insufficient power supply of the Jetson Nano's USB interface. It can be solved normally after connecting to an external 5V/2A power supply through the DC interface of the LCD.

2) When the HP audio interface is in use, it may be necessary to set the sound output settings in the system.

FAQ

Question:
What should I do if I connect to the PC with LCD and it cannot display normally?
Answer:
  • Make sure that the HDMI interface of the PC can output normally.
  • The PC only connects to this LCD as a monitor without others.
  • You should connect the touch cable first and then the HDMI cable.
  • Some PC need to be restarted to make the 7inch HDMI LCD display normally.

Note: The PC must use a windows system.
