Please download the latest version of the image on the Raspberry Pi official website.
- 1) Download the compressed file to the PC, and unzip it to get the .img file.
- 2) Connect the TF card to the PC, use SDFormatter.exe software to format the TF card.
- 3) Open the Win32DiskImager.exe software, select the system image downloaded in step 1, and click‘Write’ to write the system image.
- 4) After the image has finished writing, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt, then save and quit the TF card safely.
max_framebuffer_height=1480 max_usb_current=1 hdmi_group=2 hdmi_mode=87 hdmi_timings=320 0 80 16 32 1480 0 16 4 12 0 0 0 60 0 42000000 3
You must make sure that there are no spaces on either side of the equal sign.
