Hi everyone,  
Many of us run Node-RED on a Raspberry Pi for IoT projects, home automation, or industrial monitoring. While the web-based Dashboard is great, having a dedicated local touchscreen can make the system much more practical — especially for wall-mounted panels, control kiosks, or 24/7 operator interfaces.  
One of the cleanest solutions is using a DSI display directly connected to the Raspberry Pi. It offers better performance, lower power consumption, and a tidier setup compared to HDMI.  
I wanted to share a comprehensive technical guide that walks through the entire process:

Why DSI is preferred over HDMI for embedded/Node-RED projects  
Hardware requirements and DSI cable connection (including polarity and locking)  
Step-by-step software configuration (raspi-config, config.txt, dtoverlay, resolution settings)  
Touch screen setup and calibration  
Advanced optimizations (GPU memory, hardware acceleration, multiple displays on Pi 5)  
Common troubleshooting (black screen, wrong resolution, touch not working, flickering, etc.)  
Best practices for reliable industrial/continuous operation

Here is the full detailed guide:  
**[How to Connect Raspberry Pi to a DSI Display](https://www.aptusdisplay.com/info-detail/how-to-connect-raspberry-pi-to-a-dsi-display)**  
It’s written from a practical embedded perspective and should be very useful for anyone building a local touchscreen interface for Node-RED (whether using the standard Dashboard, ui-dashboard, or custom setups).

While many of us might agree with this. The downside is the apparent lack of high-level UI tools that allow easy UI creation that is the signature of Node-RED with Dashboard or UIBUILDER.

If there are good UI tools that fit into Node-RED's JavaScript/HTML focus, it would be sensible to mention that in your article.
