While the scaling works the issues that can't be fixed are what happens when you use non-native LCD resolutions. Read http://en.wikipedia.org/wiki/Native_resolution
This means that while 7 does this quite well, the issue of non-native resolutions mean that you will still see less than optimal display compared to the native resolution.
Hope this helps,
Thinking of buying either a 1280x800 or a 1680x1050 15.4" screen on a Lenovo T500 laptop. When I'm at home I need 1280x800 since I'm a bit away from the screen but for example on a train 1680x1050 would be better since I then would be closer to the screen.
So my question, how good is the DPI scaling in Windows 7? Can I by using the scaling function (not XP style scaling) be able to make the 1680x1050 screen look like a 1280x800 screen?
