Question about Dell Optiplex 755 Ultra Small Form Factor Intel Celeron Processor 430 1.8GHz, 512K, 800... PC Desktop
I have a DVI splitter, connecting 2 monitors to my 755
with both connected, when i click "identify monitors" under the display settings in control panel, both are listed as "1"
if 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...
any ideas why i cant save the extend desktop setting???
Connecting Two Monitors
Use the cable adapter to connect a VGA monitor and a DVI monitor to the DVI-I connector on the back panel.
When you connect two monitors, the video driver will detect this connection and activate the multimonitor functionality.
This is the only way to enable extended display. If you use a standard splitter and connect two DVI montors, the display will only be mirrored.

Hope this helps! Please rate your feedback!
