PCoIP is a high-performance display protocol designed and developed by Teradici (http://www.teradici.com/). It has been purpose built to deliver virtual desktops over the LAN or WAN and to provide end users with the best feature-rich desktop experience.

With PCoIP, the entire screen content is compressed, encrypted, and encoded in the data center before transmitting only the pixels across a standard IP network to PCoIP-enabled endpoint devices (such as zero clients) that use the hardware-based Teradici Terra 1 or Terra 2 chipset, or to Windows, macOS, or tablet devices running the software-based Horizon Client. The key thing to remember is that no data ever leaves the data center.

PCoIP supports high-resolution, full-frame rates, 3D graphics, HD media, multiple displays (up to four, depending on the endpoint device), and high-definition audio. PCoIP also supports USB peripheral redirection.

Unlike some legacy display protocols that were built just to deliver applications, PCoIP was designed and built from the ground up, specifically to deliver a full desktop experience, taking advantage of Teradici-based zero clients with an integrated graphics acceleration technology built into the silicon on these devices, or software-based clients. PCoIP ensures the best user experience, regardless of the end user location, whether that is on the LAN or even across a WAN. It adapts, dynamically adapts based on network conditions and user policy.
