MHL-Adapter for fairphone 4

I want to connect my Fairphone 4 to a video projector. I need it for education in smartphone usage.
Is it possible? Do you know an MHL adapter or another adapter USB2 to HDMI working without problems?

As for the original question: I have tested a ATEN UC3008 successfully. But it does not seem to be sold any more. I expect any follow-up product should work at least as well.

Edit: The direct follow-up version seems to be the UC3008A1

(Side note: The term “beamer” does not actually mean in English what you think it means. :wink:
I’ve changed your original post accordingly to avoid confusion.)

:slight_smile: Thank you.

But my smart phone is quite “handy” :wink:

Wow! 34,98€ is an expensive buy for a voluntary job without salery.
Does someone have positive experience with a cheaper device?

You can find it for about 30€ online at quite some places. But yes, that only marginally reduces your issue. :wink:

If an adapter is too expensive for you, you might consider to go a completely different way:
mirror your phone screen to a PC and connect the PC to the video projector

scrncopy uses at least one lib not available on my Debian Sid.

It works in a virtual box running Windows 10. Thank you.

A less expensive adapter USB2 to HDMI is preferred. :wink:

EDIT: Since scrcpy is not availabe in Debian sid, I compiled it myself. It works now and seems to be a sufficient solution. I’ll see how it goes in the classroom.

Thank you!

Using a USB 2.0 adapter is not efficient - these contain a chip (DisplayLink) that needs to be powered from your phone. USB-C to HDMI adapters are passive, which means that you have a longer battery life when connected to the projector.

You could use a USB-C dock, then you should be able to both power the phone and use HDMI (or other video ports). I see these are available from about €30 as well. That would be the better solution if you are looking at a cost of €30 anyway.

Ulgy, but only 20,-: The FrameWork HDMI module has been used successfully on a smartphone. Can’t find that image in the forum now, though.

That’s meant to plug into a Framework Notebook.
To use it with a smartphone, it may be advisable to connect it via a USB2 extension cord,
