Can you have a different desktop background on each monitor with nvidia dual monitor setup running Windows 7 OS without downloading software?
Did you read the first link? I thought it would work for Windows 7... it is possible in Windows XP and Windows 7 is supposed to be better OS but I guess not in some aspects.
Apparently it's not possible to use different desktop background on each monitor in Windows 7 without 3rd party software, but maybe the workaround at andrewblock.net will help. The nvidia dual monitor setup should not make a difference..
This is the only information I found on using different wallpapers without software... some other comments say it's only possible with software, and others say the option was in the Windows 7 RC Edition but was not included in the Official release... so if this doesn't help you will have no other option but to use software.
I did read the first link following the Windows XP instructions, but I couldn't find all of the windows that were mentioned. I kept looking around in different places for the correct items to click on, but couldn't find them. I will try the workaround at andreblock.net.
