I just got a new monitor - a 19" Belinea 1925 S1W with a native res of 1440x900, its running on a computer with an SiS 760GX integrated graphics card. Both the monitor and the Graphics card have the latest drivers installed, and lots of resolution options are availible, however windows will not let me set the monitor to run at it's native res, i've run out of ideas, help!
