Currently the cases are as follows:
Width and height both set to 0 - player takes screen size (correct)

Width and height specified - player will correctly show with the dimensions as specified in the profile (correct)

Width specified (!=0) and height set to 0 - player will appear as minimized in the taskbar (incorrect)

Width set to 0, height specified (!=0) - player will actually take both width/height from the screen size ie it will be the same as if both values were set to 0 (not quite correct).

We'd expect that player will always take into consideration the value set in display profile and if it is set to 0 then it will take the screen value for that setting.

Perhaps we could also validate the negative values in height/width if such are provided in the profile, presumably player would just ignore the "-" so -1920 would be the same as 1920 or set it to screen size if we detect negative value.
