When you see scrollbars, directx is not working.
Without directx the aspect ratio is fixed, if server and viewer have a different aspect you get black bands.
I have no idea why directx doesn't work...sorry
go to "C:\Windows\System32" and run "dxdiag.exe". At the second tab there should be all 3 directx functions enabled/active. Otherwise something with directx is wrong in general.
