Windows 8 will offer improved mouse targeting along shared monitor edges, too. If you move your mouse cursor from one monitor to another across a shared corner, for example, mouse movement will remain fluid and the cursor movement won't trigger an event on the second monitor. Microsoft has also implemented "real" corners in Windows 8. If you have a 30-inch screen next to a 22-inch screen, with their bottom edges aligned physically and in the control panel, your mouse cursor will hit a hard edge and not travel to the second screen, where the two screens do not overlap. This intuitive arrangement is easy to get used in a properly configured setup.
Setting up Multiple Monitors in Windows 8
To test the new OS's multimonitor features, we installed the recently released Windows 8 Release Preview on an Intel Core i7-3770K-based system and configured dual monitors with the integrated Intel HD 4000 series graphics, with a discrete Nvidia graphics card, and with a discrete AMD graphics card. In all three configurations, the setup process proved to be very simple.
Intel HD Graphics
The Windows 8 Release Preview detected and installed the necessary graphics drivers for Intel's HD 4000 series graphics engine without requiring any user intervention. With the Intel graphics, we simply connected a second monitor, which the operating system immediately recognized and enabled. The only steps we had to take (as in any graphics configuration) involved specifying the monitors' relative positions, in Windows 8's Display Settings control panel.
To configure the monitors' positions, first bring up the desktop, then right-click the background, and then choose Personalize from the menu. In the resulting window, click the Display link, and then click Change Display Settings. In the Change Display Settings window, click and drag the virtual monitors to mimic your physical setup. Click OK, and you're done. (Another way to bring up the necessary control panel is to open your Start menu and enter Display Settings in the search field).
