Working with multiple monitors does not allow multiple desktops

I have attached a second monitor to my laptop which runs Windows 7, however, I need to set different resolutions for different monitors, because the display does not fit to fill the screen on both monitors.

It is also noted that the display is replicated, and I would like to have the effect of having different desktops e.g. being able to use different applications such as debugging code on one monitor on an IDE such as Visual Studio, and, viewing the browser on the other monitor.

Currently it does not seem possible since the behavior seems to be that the same resolution is replicated on both monitors.

Are more than two monitors supported?

Set it to extended mode instead of duplicate, then you can use both independently.

Using the Replicate option (Actually it's not called that. It's called Duplicate Displays) you can't have 2 different screen resolutions. Only with the Extended Desktop option can you set the res separate for each monitor.

No you can't have 2 different desktops. Two different start bars or menus or different background. But you can open different programs on each monitor.

I run a Dual Monitor setup with 2 different Dell monitors. One 18" standard old school and one 21" wide screen. Chrome always open on the 18" screen, Thunderbird on the 21", Virtual Machines on the 18" and Word, Excel and other programs on the 21".
