When used on Raspberry Pi, you need to modify the "config.txt"
Add the following code to the config.txt file:
max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_timings=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3
Note: If it is Raspberry Pi 4, you also need to comment out dtoverlay=vc4-fkms-V3D.
