One of our customer is using the MTR system with Logitech Meat up. But the selfpreview is too small. We have placed the camera in front of a large table, so there is almost 3/4 meter between the user and the tv-screen (selfpreview). See my attachment for the example of how small the selfpreview is.
I couldnt find a solution to make this bigger. I tried to change the resolution which is not really helpfull. Also connected the mouse to the computer but it does not respond when you click on the selfpreview. Even the XML config does not have this setting.
