Absolutely brilliant 4" Touchscreen for a great price. After finding out how good it was I ordered a second straight away.
The instructions provided are spot-on. I installed remote login into the Raspberry Pi first (just in case!). I now have one on a Raspberry Pi 3B and a Pi 4B.
For the Raspberry Pi 3B which only supports one display. IF the HDMI cable is present then its switches to display on the HDMI. The touchscreen part is very accurate. Alas, my fingers are not. It's so clear and readable.
