How Do I Increase The Video Conferencing Screen Size On TeamViewer9

How Do I Increase The Video Conferencing Screen Size On TeamViewer9 ?.

I use TV to do maintenance on my daughters Uni laptop from home.


Anyone know where the config files are ?. that are for the Video Conferencing Screen Size as it's very small ?.
There are two settings on a drop down list but both are small, largest only about 50mm x 50mm (2"x2") , I would like half a laptop screen size if possible.

I looked at
/home/team4mike/.config/teamviewer9/config/
/opt/teamviewer9
/usr/lib/wine

But could not find anything that looks like a Video Conferencing Screen Size config file.
It must be somewhere.
