                1. The test is for systems which allows primary display
                   selection in multiscreen systems.
                   Set the system primary screen to be the rightmost
                   (i.e. the right screen in two screen configuration)
                   This can be done by going to OS Display Settings
                   selecting the screen and checking the 'Use this device
                   as primary monitor' checkbox.
                2. When done, click on 'Frame on Primary Screen' button and
                   see where the frame will pop up
                3. If Primary Frame pops up on the primary display,
