While running Selenium tests using the Chrome driver on a virtual machine created in vSphere/VMware, the window size seems to be limited. Our tests try to set the window size to 1920x1080, which results in the following log messages:
2019-11-04 10:14:55.1255 WARN Reloading WebDriver.

As you can see the window size is increased slightly but not to the configured size. Configuring a lower window size, like 800x600, results in the following log messages:
2019-11-04 10:14:55.1255 WARN Reloading WebDriver.

So, in this case the window size was updated successfully. So it seems like the window size is limited in some way, likely by the screen resolution of the VM.
We've updated the VMware tools on the machine and we also increased the video memory of the machine from 8 to 16 MB. Both of these attempts resulted in the same behaviour.
So, the question is: does anyone know how we can increase the screen resolution of the VM (e.g. in the vSphere web client) so our Selenium tests can run with a window size of 1920x1080?
