To use the LCD with the Raspberry Pi official image, driver should be installed first. Please refer to the user manual. However, for the first testing, you may want to use our provided image directly. Why the LCD still doesn’t work with the Waveshare provided image? Make sure the hardware connection is correct and connects fine. Make sure the image in TF card is burnt correctly. The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact. Which power supply should I use? It is strongly recommended to use a stand-alone 5V/2A power adapter, because the PC’s USB port might have not enough power to support the Pi and LCD. 1 Review Hide Reviews Show Reviews 4 Waveshare 4inch HDMI LCD, 800×480, IPS Posted by Harry Adams on 2019 Jun 9th A nice little display. Good colour and resolution. A bit hard to read text. Setup was straight forward using Method 1 from the User Manual. **Note** There is an error in the manual section on calibration. In Step 4, in the last line in the box the character string “d./99” should be “d/99” – without quotes. You get a “directory does not exist” message if the period is left in. When the calibration is finished, you will see 4 numbers that you need to write down. The aforementioned line invokes the nano text editor. Type in the example as shown in the black box in the manual but substitute the 4 numbers you wrote down in place of the 4 numbers given.
