Thanks Luca but I tried with my Amazon stick and unfortunately it is not recognised either (via HDMI to the laptop the same in green).

I still have a Chromecast at home. I'll test whether you can access it via the beamer without a remote control. If so, that would probably be the option you have left. The Chormecast also comes with a remote control or you can control it with your smartphone.

Thank you, but this was not supplied with my projector, but unfortunately I noticed this too late and complained about it. Apparently there is no replacement remote control for the projector and I couldn't get it to work using an app or something similar. Since a return is apparently not possible, I have been without a projector for a while now and am therefore grateful for any support :-)

I have personally always used the remote control supplied with the projector.
