If you've got things set up properly, you'll see an endless 'mirror-in-mirror' view of your screen. You'll also need to configure each on the machine you'll be using, but it's possible to test your connections from your main PC by allowing loopback connections. But we recommend keeping the default Auto Select Best Settings options, where they're available. The Viewer also allows many options, such the level of access and control you want to allow, the display settings, and miscellaneous options such as disabling clipboard transfers.

Setup involves creating a password and allowing UltraVNC through your firewall when you first run the Server. We ran UltraVNC's 64-bit version on Windows 7 PCs.Īs with other VNC apps, UltraVNC has two main parts, the Viewer and the Server, and the download installs both. But anyone who has configured their network settings should be able to set up a VNC connection using UltraVNC. The online documentation includes screenshots but is a bit thin in places and assumes some knowledge on the user's part. For example, you must install the client (Viewer) on one system and the Server on another, and both PCs must allow remote access. It's easy to use, as VNC packages go, but it's not really for beginners. Freeware, actually: UltraVNC is free but powerful enough to provide customer support and remote administration. UltraVNC lets anyone create VNC connections between two or more PCs running its software. Based on a simple, robust protocol, VNC connections let you remotely view and control one computer from another using the Internet or a private network.

VNC stands for Virtual Network Computing.
