Mirror Setup Windows 7


I have been researching how to mirror display's for a few days now, and it seems to be one of the most difficult things to do, or get an easy answer for. I have Windows 7 64-BIT, SLI GTX 260's & EVGA 750i motherboard. (If that matters) I am trying to mirror my desktop display to my 51" Samsung PN51D7000. I have DVI going from Card 1 to Monitor, and DVI/HDMI adaptor going from Card 1 (output 2) to TV. I got it working for dual displays, extending monitors etc. But I see no option for mirror, cloning or anything. I have updated to latest driver for MB and Video card. What's next?

Thanks in advance.

  1. I'm sorry that nobody replied to your post. Hopefully you're not still having this problem after almost 3 months but in case that you are, I'll tell you what I know. From previous experience, I have seen situations where there wasn't an option to do this and I could never find out why and ended up having to use the video card's driver software. Either way, under

    "Control Panel\Appearance and Personalization\Display\Screen Resolution"

    you should have a drop down menu by the field 'Multiple Displays' with an option to 'Duplicate These Displays.' That's the option you'd want to select.

    But, like I said earlier, that option doesn't exist sometimes for whatever asinine reason I could never discover. So, going through Nvidia Control Panel or ATI Catalyst Control Center was the only way I could get it to work.
