I have a Compaq notebook Evo N610c with Radeon Mobility 7500. The problem is that the extended desktop feature of the card was cancelled, probably from firmware. I found out a site that solved this issue, but on Mac computers ( http://www.rutemoeller.com/mp/ibook/ibook_e.html ).

Do you have any ideas how to enable back the extended desktop feature ?

Thank you

What exactly do you mean..
TV out ? VGA out (to monitor) ? do you have the connections ? OR something else

BUT you could try this
Remove ALL you ATI drivers and control panels
Goto ATI and download the latest Catalyst 3.4 drivers (it will not be under your card just look for standard Readon 7500 or similar)
Also get the control Panel while there.

Use the Mobility moder (from here at driver heaven)
Install the drivers, then the control panel and see if that works.

Check for BIOS updates at HP/compaq to see if that helps as well.
