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-finger 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

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.
Avoid EMI (electromagnetic interference) while using this display. The capacitive touchscreen may misbehave when placed near some power adapters, mouse, or data cables.
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.
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.
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 config.txt. Please refer to the official page for more details: https://www.raspberrypi.org/documentation/configuration/config-txt/video.md

CONNECTORS EXPLANATION

The connectors on the back of the display

Use the Display

Power the display through the PWR port (Micro USB power) until you see the UCTRONICS logo.
Connect the display to your video output device with an HDMI cable or the HDMI-to-HDMI adapter until you see the video feed. Use the micro-HDMI to HDMI adapter if the connector does not match.
Connect the USB touch port of the dis-play to the USB port on the video output device to enable touchscreen features.

Add the native resolution to RPi

The input resolution may be downscaled to fit 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.
