My 3rd monitor is stuck at 800x600 in windows 10

I am having some issue creating a 3rd monitor for my laptop. I have an HP Pavilion 15-p080ca Notebook, with an attached AOC e1759fwu USB Monitor. The graphics card is an AMD Radeon HD 8610G.

I am trying to hook up a tablet which supports 1920 x 1200 resolution. The way to do this is to go into your device settings, detect monitor, and when the 3rd uncoected monitor tus up, you try and coect to it via VGA and it activates. My problem is this 3rd monitor is defaulted to 800x600 and the option to increase is grayed out.

This occured no matter how I try and add a 3rd screen, either by using an android app, or trying to set up the screen to be viewed by Teamviewer.

I have updated my graphics drivers, and no matter what I try, I caot get better resolution. DOes anyone know of a way to force it to have better resolution?
