Like VNC, ZoneScreen able to mirror local desktop to another computer in the network. The main difference is that it also allows extend desktop, not only mirror it. Also, you could use ZoneScreen for Windows Mobile to extend/mirror your desktop to screen of your handheld.     All you need for ZoneScreen to work is network connection between your computers (your computers are both connected to the same network, or connected directly with cross-over cable or 1394 firewire cable, etc). In case you are using Poket PC, you may also use connection provided by ActiveSync (using cradle cable, IR port, etc).

How It Works     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 (details).

Windows Vista and Windows 7: For these operating systems use Windows XP builds, but keep in mind two important limitations. Due to Windows Display Driver Model (WDDM) architecture, ZoneScreen virtual display driver can't run unless XP video drivers are installed on main video adapter. Otherwise only desktop mirroring would work (details). For Windows Vista x64 and Windows 7 x64 digital signature enforcement for kernel drivers is also applied (ZoneScreen display driver is not WHQL-signed), so virtual display driver is also not loaded unless this enforcement is disabled (details).

Other systems (Linux, PalmOS, etc): Linux and PalmOS are not supported by ZoneScreen itself, but it is possible to use cross-platform implementations of VNC as a replacement for ZoneScreen wizard. For example, server machine with Windows XP, ZoneScreen virtual display driver and and VNC server could use client machines with any operating system which supports VNC client. Because virtual display is completely identical to normal display, VNC server could be transparently used above ZoneScreen display driver (was tested with server from RealVNC 4.1.2.0). If you are interested in PalmOS, PalmVNC is the VNC client for it. Also you could run ZoneScreen wizard (build for Windows 98) in Linux under Wine. Release notes: - Network traffic between ZoneScreen client and server is not encrypted. Therefore all information you send to client is potentially available to everybody in the network. Please keep this in mind. - Limited set of screen resolutions is hardcoded to virtual display driver, and up to 10 custom resolutions could be defined using ZoneScreen Wizard. - Supported color depths are 8, 16, 24 and 32-bit. - ZoneScreen wizard supports command line scripting. Launch 'zsserver.exe /?' to see available options. - Windows XP Sp1 has a bug, described here, which affects ZoneScreen display driver. Upgrade to Sp2 solves the issue. Note that this affects only server machine (client machine do not need ZoneScreen display driver to be installed). New Versions of ZoneScreen     If you need ZoneScreen in a different configuration (operating system, CPU architecture or language), or you have suggestion for a new feature to be implemented, you are welcome to write about.
