Intel 946GZ suddenly NO MORE Extend Desktop Display Setting - Only TWIN + CLONE

[idata]

I am having Acer L310 with Video -Integrated Intel® Graphics Media Accelerator 3000 System Chipset-Intel® 946GZ + ICH7 for many years.

Have 2 monitors connected to it as extend desktop setting.. Working fine when it was running XP till upgrade to Vista Home. Happy user for the Intel support of multiple moniors.

Just a few days ago, there was a recommendation to upgrade driver for my monitor and display adaptor by the MS Window - auto update. After accepted

and let it upgrade the drivers for DELL Monitor driver and Intel 946GZ Express Chipset Family... NOW When I click on "Personalize" I can only see one monitor and not two. If I goto 96GZ adaptor's graphic property, the display device still have option for single or mulitple displays. But for th multiple display, I can only choose twin or Dual Clone - which means both monitors display the same content. NO LONGER HAVETHE OPTION TO extend the desktop

I tried reinstall monitor or older Intel 96GZ adaptor drivers... it did not help.

Any kind advise appreciated. My latest adaptor driver version for Intel Graphic 946GZ is 1.11.5.64.1624

I have a friend throw an idea to install 945 instead, as it is for mobile.... I think that unlikely to make sense, to even try.

Hello,

I suggest you to try updating the driver installed on your system. The latest generic driver is posted here:

http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Desktop+graphics+controllers&ProductProduct=Intel%C2%AE+82946GZ+Graphics+Controller&ProdId=2582&LineId=1100&FamilyId=39 http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Desktop+graphics+controllers&ProductProduct=Intel%C2%AE+82946GZ+Graphics+Controller&ProdId=2582&LineId=1100&FamilyId=39

You can also try using a previous version of the generic driver in order to troubleshoot this issue. Or test the latest driver that has been customized by your system manufacturer which is provided directly by them.

Furthermore, try updating the BIOS of the motherboard you are using.

In addition check the information related on the following URL:

http://www.intel.com/support/graphics/sb/CS-030721.htm http://www.intel.com/support/graphics/sb/CS-030721.htm

If the issue persists, the problem might be a corruption of the operating system itself triggered by using that generic driver from Microsoft. In that case you might need to reinstall the operating system.
