Dual monitors can't extend desktop

\015 I have a DVI splitter, connecting 2 monitors to my 755\015\012with both connected, when i click "identify monitors" under the display settings in control panel, both are listed as "1"\015\012if i select the 2nd monitor and check the "extend desktop..." box and click apply, it auto-unchecks the box, so both monitors remain as mirrors of each other...\015\012any ideas why i cant save the extend desktop setting???\015

Answers :

Connecting Two Monitors
\015\012\015\012Use\015\012the cable adapter to connect a VGA\015\012monitor and a DVI monitor to the\015\012DVI-I connector on the back panel.


\015\012\015\012When\015\012you connect two monitors, the video driver will detect this connection and\015\012activate the multimonitor functionality.
\015\012\015\012This\015\012is the only way to enable extended display. If you use a standard splitter and\015\012connect two DVI montors, the display will only be mirrored.
