Test Execute runs tests at screen resolution or less than 800x600 on a slave machine

Hi,

I'm running tests from TestExecute on a slave machine with Jenkins.

The problem is that the screen is displayed at resolution or less than 800x600 and the some objects from the browser are not visible becasue the browser looks like is minimized and thus cannot be clicked.

Is there an option to change the resolution at wich the screen is rendered so the tests will not be afected by the minimized displayed?
