TROUBLESHOOTING
Q1: Why am I getting a UCTRONICS logo instead
of the video feed for about a minute when boot-
ing up?
Our drivers need to be loaded on startup, which takes a
little time. It’s expected to see the UCTRONICS logo. The
staying logo also serves as a self-detecting method, and
if the driver is not correctly installed, the logo won’t go.
Q2: The screen stays after I shut down the system.
How do I turn that o?
Like the red indicator light on the Pi, it’s normal for the
screen to stay because the Pi board still feeds power to
it. Please unplug the power cable of your Pi or toggle
the backlight on/o button of the screen above the Pi
power port.
Q3: Why is my desktop monitor not responding to
the dual-display setup?
The native resolution of the display is 480x320, which is
not supported by all monitors. For any dual-display
setup, make sure you set the resolution of the system to
one that’s supported, like 640x480 or 1920x1080. Howev-
er, higher resolutions may leave the contents unreada-
ble on 3.5” screens.
DRIVER INSTALLATION
The screen will not work without installing the driver.
Connect to the Pi and install the driver before using the
screen. There are 2 ways to control the Raspberry Pi.
1. Connect the Raspberry Pi to another working
display.
2. Connect with an SSH client like PuTTY. Make sure
your Pi is connected to the Internet before you
proceed.
Run the following commands to download and install
the LCD driver.
For dierent operating systems, the step 3 varies. You
need to enter the folder with the name of your specic
system. Take the Raspbian for example:
