5-Inch HDMI LCD Dis-
play with Capacitive
Multi-Touch
Touchscreen
SKU: U6103
Introduction
This UCTRONICS Display is a 5” LCD capacitive
touchscreen display which receives video/
audio signals through the HDMI port, and the
touchscreen input through a micro-USB port.
It requires three connections: 1)a USB cable
connected to a 5V power supply, 2)an HDMI
cable and 3)another USB cable (for
touchscreen) both connected to the video
output device. The 5-nger touch feature
requires OS and software support.
It is well integrated with single-board com-
puters such as the Raspberry Pi series, and
serves as a small screen for your PC or video
game consoles. The micro-HDMI to HDMI
adapter cable is to use with micro-HDMI de-
vices like the Raspberry Pi 4, and the HDMI-to-
HDMI connector is an alternative to a stand-
ard HDMI cable.

Note
1. The native pixels of this display is 800 x 480. It will
downscale HDMI inputs with larger resolutions and
squeeze the original aspect ratios to match its own.
2. Avoid EMI (electromagnetic interference) while
using this display. The capacitive touchscreen may
misbehave when placed near some power adapters,
mouse, or data cables.
3. Feed enough power to this display with an extra
cable. An underpowered display may encounter
unstable connections. Power adapters are preferred
over onboard USB ports. We’ve included one cable,
but you need two for both power and touch.
4. The touchscreen double-click action is not per-
fectly supported in Raspbian due to the limited
response time and system driver issues. It will work
properly on another operating system such as Win-
dows 10.
5. The USB touch port also takes power input, so you
can try to power the display and add touchscreen
support with a single cable. However, the Raspberry
Pi does not natively support HDMI hotplug, and you
need to set hdmi_force_hotplug=1 in cong.txt.

Add the native
resolution to RPi
The input resolution may be downscaled to t
the native pixels, which will make the on-
screen contents unreadable. Follow the steps
below to add the native 800 x 480 resolution
to the Raspberry Pi for a one-to-one mapping
with regard to pixels.
