•Note 1: Input voltage exceeding the maximum value or improper operation may cause permanent damage to the device.
•Note 2: The input current should be ≥800mA, otherwise it will lead to start-up failure or abnormal display, and a long time in an abnormal state may cause permanent damage to the device.
•Note 3: Please do not put the display in a high temperature and high humidity storage environment for a long time, the display needs to work within the limit value, otherwise it will be possible to damage the display.

EDID Sequence Parameters

If the system of the main control board can automatically identify the EDID for display, there is no need to set the relevant timing parameters additionally.

Otherwise, you can refer to the following EDID settings:

Pixel Clock	H Addressable	H Blanking	V Addressable	V Blanking	H Front Porch	H Sync Width	V Front Porch	V Sync Width	H Image Size	V Image Size	H Border	V Border

Onboard Interface

User Manual

Working with Raspberry Pi

Hardware Connection

Connect the Touch port to the USB interface of the Raspberry Pi.
Connect the HDMI interface to the HDMI interface of the Raspberry Pi.

Software Setting

Raspberry Pi OS / Ubuntu / Kali and Retropie systems are supported for Raspberry Pi.
When the LCD works on these systems of Raspberry Pi, the resolution must be set manually, otherwise, it will result in incorrect display resolution and affect the experience.

1. Please download the newest image from the Official Raspberry Pi website.
2. Download the compressed file on the PC and unzip it to get the .img file.
3. Connect the TF card to the PC and use SDFormatter to format the TF card.
4. Open Win32DiskImager, choose the image prepared in the first step, and click "Write" to program the system image.
5. After programming, open the config.txt file in the root directory of the TF card and enter the following codes at the end of config.txt. Then, save and safely eject the TF card.

hdmi_group=2
hdmi_mode=87
hdmi_timings=1600 0 80 32 112 720 0 30 3 33 0 0 0 60 0 87000000 0

6. Insert the TF card into the Raspberry Pi, power up the Raspberry Pi, wait for a few seconds normally and then it will display normally.

Linux Software Brightness Adjustment

Using the DDC/CI program, here is an example of the ddcutil tool.

#Install ddcutil tool:
sudo apt-get install ddcutil -y
#Detect DDC/CI monitor support:
sudo ddcutil detect
#Adjust monitor brightness, <value> should be modified to 0-100 
sudo ddcutil setvcp 10 <value>

Working with PC

Support Windows 11/10/8.1/8/7

How to use:

Connect the Touch port of the LCD to the USB interface of the PC, and Windows will automatically recognize the touch function.
Connect the HDMI interface of the LCD to the HDMI interface of the PC, and Windows will automatically recognize the display function.

Note:
Some PCs do not support HDMI devices plug-and-play, usually after rebooting the system can be used normally.
If the power supply of the USB interface is insufficient, the LCD will flicker, after connecting the external 5V 1A power adapter to the LCD's Power interface, it can be restored to normal use.

Windows Touch Calibration

Take Windows 10 as an example:

1. Enter the Windows setting 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!)

Windows Software Brightness Adjustment

1. Download and install DDC/CI applications, such as the open-source Twinkle Tray.
2. Open the software dimming icon, it will recognize the Waveshare monitor and adjust the monitor backlight brightness by sliding the scroll bar.

3. You can also enter the DDC/CI application settings screen to enable contrast adjustment, volume adjustment, and other functions.

FAQ

Question:How to use PWM control 10.4HP-CAPQLED backlight?

Answer:

The default state is to support software adjustment, it is recommended to check the #Linux Software Brightness Adjustment, or you can also use the PWM to control the backlight in the following steps:

As shown below, first remove the original soldered resistor (shown in the red box), and then connect the lower pad of that resistor (shown in the yellow circle) to the P1 pin of the Raspberry Pi, then you can use GPIO to control the backlight.

gpio -g pwm 18 0
gpio -g mode 18 pwm (Occupied pins are PWM pins)
gpio pwmc 1000
Brightness control:
gpio -g pwm 18 X (X takes values between 0 and 1024, with 0 being the darkest and 1024 being the brightest.)
