I am using a 3.5'' TFT LCD Display with the Raspberry Pi 3 (and latest Raspbian Stretch). Can anyone please tell me how I can change the screen resolution (on the screen it says 480x320) of my Rasperry Pi.

I installed the screen like they described in this tutorial. But now I have an overflow (parts of the screen are out of the provided Screen-Size (eg. Dialogs, System settings dialog, ...). Changing the /boot/config.txt values to (as described here):

overscan_left=24
overscan_right=24
overscan_top=10
overscan_bottom=24

framebuffer_width=480
framebuffer_height=320

sdtv_mode=2
sdtv_aspect=2

did not helped. Any clues? Thank you.

  • Did this ever get solved? I wanna run at a different resolution on the GPIO screen – Barrie Reader Mar 11 '22 at 18:25
  • Hi @BarrieReader, I'm sorry to tell you that I haven't tried to solve this problem since 2017 and I do not recall that I have fixed it. I hope you can find a solution to your problem. – natterstefan Aug 15 '22 at 10:35

Try by changing parameters this way in /boot/config.txt..

hdmi_drive=2

hdmi_group=2   

hdmi_mode=16

overscan_left=20
overscan_right=12
overscan_top=10
overscan_bottom=10
