Change output resolution

How can I change output resolution?
From the terminal I receive that it cannot determine the screen resolution and starts in high resolution. This slows down the display on the TV very much.
Is there a file where I can set the output resolution?

If you mean the latency, I doubt it is related to the output resolution.

You cannot change the resolution currently. In fact, it currently is even hardcoded to FullHD rather than using the information discovered from the sink.

Thank you for your answer.
At the moment I tried it on a tablet with little power, I think that's the problem.
Anyway, it would be nice to change the values!
Thank you for your work, much appreciated

Right, you should probably try to install gstreamer-vaapi (or whatever it is called in your distribution). This encoder should be accelerated using the graphics card, which could improve performance considerably.

As for resolution choosing; what you are describing is quite a corner case unfortunately. That said, we really should be using the resolution that the local screen has whenever it is available on the sink side. And it should be really simple to fix this; I think hardcoding it to FullHD was mostly to rule out errors at the time.

Hi, I tried to install
gstreamer1.0-vaapi intel-media-va-driver-non-free i965-va-driver-shaders
In addition, I have updated other packages in ubuntu 19.10
Now I can't even connect to the TV.
these are the logs:
