Windows 7: Windows 7, ATI 3870 X2 and cloning the monitor. HOW!@??

Windows 7, ATI 3870 X2 and cloning the monitor. HOW!@??

I have a 22 inch monitor on my desktop. I also have a 46 inch Samsung LCD HD TV.

I want to clone my display so what is seen on the monitor, can also been seen on the TV across the room.

Extended desktop works but I need to be able to CLONE it.

I can't for the life of me figure out how to do this on Windows 7. Any help would be great.

Video card in question is an ATI 3870 X2 with 3 DVI outputs and one HDMI output.

Right click the desktop and choose screen resolution.

You can set it there.

Next to multiple displays -- set that to duplicate.

Two months later and no new info?

I've complained on the ATI forum about this too. No replies there either.

Make sure both resolutions are the same and that the DVI ports u use are from the same side of the card (the Printed Circuit Board side).

I had the exact same issue with a different ATI card. I fixed it by using a much older Catalyst driver.
