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.
I’ve changed your original post accordingly to avoid confusion.)

Thank you.
But my smart phone is quite “handy”

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.
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.
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,
