Problem with Screen Resolution when starting sessions with a particular computer

[Stackmo]

I have a Media PC that when starting a session with, will default to a Teamviewer screen resolution of 1400x1050(scaled). This was the resolution of the projector I was using on my Personal PC for the first session I had with the Media PC.

I am no longer using the projector, and the native screen resolution for both Personal PC and Media PC are 1920x1080, yet the Media PC still defaults to 1400x1050(scaled).

I have also tried connecting to the Media PC from a different computer, but still have the same problem. Uninstalling/Reinstalling Teamviewer on the Media PC didn't fix the problem.

I want the Media PC to default to 1920x1080(scaled) when I start a session with it, does anyone know how I can do this?
