Another surprise was that the mouse and keyboard are apparently bundled into a USB port so that you only connect the monitor connector and a USB connector on the computer. In times when USB ports are always too short, that's a brilliant thing.
I read manuals only if something does not work or I can not find a required function. Therefore, I did not at first inserted the CD and popped me unnecessary software on the computer, but just once infected everything and watched what happened.
So after I came creeping back under the desk, I could already see that the desktop is displayed on the monitor of the notebook. Switching worked immediately. Press twice (quickly in succession) the Num Lock key that works even without driver installation.
For the notebook I use the PC monitor as a second monitor and I had to adjust the graphics settings.
Too bad I find that Windows 7 these settings are not noted. Once I disconnect the monitor connector on the laptop and plug in again, I have to adjust all things new again. But this is a problem Windows 7.
