Dual monitors, both work, both show same thing, only one detected. I have two NEC monitors LCD1. NXM LCD1. 9V connected respectively through VGA and VGA to DVI connections. Both work when Im on Linux as dual monitors, but on Windows only one is detected and they both show the same thing. What do I have to checkdo to have them work Hi. Right click the Desktop and select the Screen Resolution item. In the dialog box, use the Multiple displays drop down menu to select Extend these displays. If this does not work, click the Detect Button at the top of the screen. Hope this helps. Thank You for testing Windows 7. Ronnie Vernon MVPOne would expect this to work, but it dosnt.

ATI/device-manager-pre.png' alt='Ati Radeon 9250 Secondary Driver' title='Ati Radeon 9250 Secondary Driver' />PRO card on a PCIe slot with 2 digital connections to 2 other monitors. For the Radeon 9. Vista or Win 7 driver from ATI, but a standard VGA driver is set up by Win 7. Ive installed the Win 7 driver for the HD 2. When I try to set up multiple monitors in Win 7 Desktop right click Screen Resolution, Win 7 only recognise the one analog monitor on the card with standard VGA driver. I can find no way to make Win 7 aware of the other card and the other monitors. Detect gives no response. Ive tried installing only the driver from ATI, and Ive tried installing the driver and the ATI Catalyst 9. Control Center none of the alternatives works. Car Drivers Needed. This is a downer. It works fine on my XP x. Its so irritating and frustrating that if I dont get a quick answer on this issue, Ill put off the swich to Win 7, at least for the rest of this year. Ill consider adwicing my customers to do the same. Its a shame. I was really looking forward to Win 7.
