Multi Monitor Manager is a lightweight portable solution to control multiple monitors that are connected to a computer system from the main system. The software program will immediately display the screens of all connected computer monitors with the option to interact with each of them using the computer mouse and keyboard.

A click on a computer monitor window makes it possible to interact with the elements that are displayed on the computer screen. It is possible to resize the screen for better access. This is recommended as the default window size is rather smallish. Everything that can be done directly on a computer system with the mouse and computer keyboard can also be done using the Multi Monitor software. This includes opening and closing programs, typing text, launching commands or taking screenshots.

The multi monitor manager uses mostly cpu resources while running but barely any computer memory. Users who operate computer systems with multiple monitors might want to check out the portable software program. It was developed by Skrommel who is a member of Donation Coder. It can be downloaded directly using this link.

I came upon ZoneOS ZoneScreen at the donation coder blog which always has some great tips about new freeware. ZoneScreen supports multiple screens over network which means that you do not need an adapter that supports dual monitors, all you need are two devices that can be connected over a network.

As you can see on the picture to the left a notebook and a desktop computer display part of the same application. It is possible to use this on PDAs as well which makes it a great tool for system administrators for example who can carry the PDA with them that displays the most important information.

ZoneScreen consists of two parts: kernel-mode (running with privileges of Windows kernel) driver for virtual display (which is visible to Windows just as normal video card with monitor attached to it), and user-mode (running as usual user application like Notepad) wizard which is responsible for capturing image, transmitting it over the network, and drawing it at another computer.

Machine, whose desktop is extended, called server. Server machine have display driver installed and ZoneScreen wizard running in server mode. Another machine which acts only as external display called client. Client machine have only ZoneScreen wizard running in client mode.

Both parts of ZoneScreen (driver and wizard) are completely independent and can be used separately. This mean that in case we are interested only in mirroring desktop image, we do not need to install virtual display driver, and if we are extending desktop with ZoneScreen display driver we could use any other software, for example RealVNC, for transmitting desktop image over the network (in this case we need transfer only space of virtual display).
