Dear Concerned,I work for an NGO and we have purchased licenses for Windows 7. Now a days I am transitioning all the computers from Windows XP to Win 7.The problem I am having is that on most of the PCs like my notebook (Dell Latitude D610), Dell Optiplex GX 520, Compaq Evo D510 Small Form Factor the connect to a project option is not working. Earlier these systems used to connect with the projector whenthere was XP on them but since after Win 7 its not working. Even in the Screen Resolution I can't see Connect to a projector or the Windows + P option to connect to external display.I can't find any clue how to resolve this issue. Kindly guide me to get out of this problem.Regards,Fahad.
