@sdetweil Thanks for your input.

Regarding the single extension cord, I’ve used that approach many times in the past. Just trying to avoid all those cables and adapters.

At this time I’m not interested in Touch screen. That might change sometime in the future for another build. Thank you for pointing out what’s possible with forms input.

I don’t understand this statement: “all the apis the base consumes are all output/read only”

I neglected to mention that I did search the Show Your Mirror section a little for “USB C” before posting, but only got a few non-applicable results. Wasn’t sure what other search terms would be better?

I’ve searched YouTube and Google for a solution.

I want to build a Magic Mirror and keep all connections to the Pi 5 very compact by using the power cord to the Pi and a single cable to the monitor. This avoids multiple power cables. I do have a few other RPi’s such as a Pi 1 2011 and B+ v1.2 2014, if those are a better choice, although I’d prefer to stay with the 5.

I have this [https://www.amazon.com/dp/B095GG31KX](link url) portable monitor. It supports Thunderbolt 3.0/4.0 or USB 3.1 Type-C DP ALT-MODE.

The following 2 videos are the closest I could find to a solution to the issue below the YouTube links. The small board shown at the 00:20 minute mark in the 1st video link below (from 4-months ago) isn’t currently available and I’ve asked when an ETA would be. His project also requires this board, which is available. [https://shop.getubo.com/products/connec … 4075662611](link url)

As an alternate, I’m under the impression that this cable won’t work?

Wondering if someone knows of another project similar to this? Perhaps there’s a HAT available that would serve this purpose? For instance, would one of these work, perhaps the PCIe style? The information provide is limited for my knowledge base to interpret.

If I need a different portable monitor that’s fine as long as it’s at least as large and fulfills my goal.
