FAQ
Question 1: Does it require gpio?
Answer: Only the touchscreen requires to be connected to the GPIO pins while the display doesn't need to. However, the display needs to be powered somehow.
Question 2: Do you need to install drivers if you just want it as a monitor without touch screen? is there any configuration needed for it to work w/ RetroPie?
Answer: You needn't install extra driver if you only want it as independent monitor without touch function, but you need to connect this LCD to desktop computer via extra HDMI cable and extra Micro USB cable, the HDMI cable transfer video and audio signal, the micro USB cable supply power to LCD;
Only support 320x480 - 1920x1080 pixel range on desktop computer;
This LCD supports retropie without touch function, we need to modify the config.txt file as following:
max_usb_current=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1
Then you can use it on retropie without touch function.
By the way, this LCD supports almost all raspberry pi OS, and you need modify the config.txt file like above.
BUT besides raspbian and ubuntu, the touch function is not supported on other OS.
