Can I use Dell P2424HT as a touchscreen with MM & RPi5?

British_Kiwi

Hi from Australia
I’m just setting up my MM and had bought a touchscreen (Dell P242HT) to set it up with. It says that the touchscreen only works with the USB C connection, however, I did find a reddit post that they had got the same monitor working with the RPi5. However, they then stated that they ended up not using MM as it was more passive and used something else.

Before I return the new monitor for a non-touchscreen, can someone please tell me if it is possible to use this set-up with MM? As much as I would love some touchscreen functionality, my heart isn’t fully set on it, but I don’t want to spend hours trying to work it out (noob to this type of coding and been a long time since I did any javascript) and then find I can’t return the monitor.

Hope this is making sense. The sort of thing was hoping was either swiping pages, or clicking on events on a google calendar to see more detail etc.

Thanks :)

@British_Kiwi there are adapters

search “hdmi to usb c adapter”

@sdetweil thank you, but we tried this. we tried a USB C to HDMI cable, and then the micro HDMI adapter to plug into the RPi, We also tried a HDMI to USB adapter at the monitor end. Each time the monitor didn’t recognise any input. The monitor looked like it could see the USB C connection, but it wouldn’t display anything.

@British_Kiwi ok, fun times.

I thought I would post the solution (almost tested), we bought a hdmi to usb-c with usb power cable. We thought we had bought micro hdmi but seems not. Down side i broke the micro hdmi to hdmi adapter so once I get a new one the touch screen will work.

@sdetweil
Touch screen is now working.
Currently have a micro-hdmi adapter into the RPi. A powered hdmi to usb-c connecting from adapter to the monitor.
The powered bit is plugged into the usb a port on the Pi. Hope this helps in the future 😀
