I tested the convergence use case with an external screen, that is connected with a dongle, that uses Miracast over WiFi. In addition I tested the setup with and without a bluetooth keyboard with touchpad.
I could manage to morror the sceen in a large desktop resulution. Unfortunately the screen ratio of the vidio signal (16:10') didn't match the ratio of the external screen (16:9). The vido signal was cropped.
Further more I realised, that hte mouse respectively touch pad signals are processed with a sginificant delay. So it is allmost impossible to control the external display. I also wasn't able to activate the window mode with the tweak app.
I think, it is not an issue of the hardware. My UBports developer device is Fairpgone 2. I compared the setup with LineageOS on a weak Wileyfox Swift developer device. The external screen with Sentio and LeenaOS are very smooth and the mouse pointer response has no realizable delay.
How can I improve the performace of the convergence use case. Only with the delay, the tested setup is not usable for practice.
Shouild I test a secenrio with a wired connection? Unfortunately the FP2 has USB-B and not the full implemented USB-C to connect an external screen with HDMI. Some recommendations and experiences?
