Does Sapphire ATI Radeon HD 3870 graphic board support portrait screen orientation?

Hi, everybody!


My desktop PC equipment is the following:

AMD Phenom 9950X4 (2.6 GHz,


Sapphire ATI Radeon HD 3870 graphics card (512 MB),

Windows Vista (32 bit)

500 GB hard disc


The reason I am looking forward to some information from the forum is that recently in spite of having bought a new monitor in order to use it mainly on portrait screen orientation, I realised that I cannot do it so, given that on display settings there is no such a selection. It's true that I have not updated the drivers of my ATI Radeon HD 3870 graphic board since 2008! My query is that, if I download the last (2013) drivers available from the official site of AMD, will my graphics card be able to support portrait orientation?


Sincerely yours,
