Choosing a Display Protocol
A display protocol provides end users with a graphical interface to a View desktop that resides in the
datacenter. You can use PCoIP (PC-over-IP), which VMware provides, or Microsoft RDP (Remote Desktop
Protocol).
You can set policies to control which protocol is used or to allow end users to choose the protocol when they
log in to a desktop.
NOTE When you check out a desktop for use on a local client system, neither of the PCoIP or RDP remote
display protocols is used.
VMware View with PCoIP
PCoIP is a new high-performance remote display protocol provided by VMware. This protocol is available for
View desktops that are sourced from virtual machines, Teradici clients, and physical machines that have
Teradici-enabled host cards.
PCoIP can compensate for an increase in latency or a reduction in bandwidth, to ensure that end users can
remain productive regardless of network conditions. PCoIP is optimized for delivery of images, audio, and
video content for a wide range of users on the LAN or across the WAN. PCoIP provides the following features:
n
You can use 3D applications such as Windows Aero themes or Google Earth, with a screen resolution of
up to 1920 x 1200. With this non-hardware-accelerated graphics feature, you can run DirectX 9 and
OpenGL 2.1 applications without a physical graphics processing unit (GPU). This feature provides
acceptable performance on the WAN, up to 100ms.
n
You can use up to 4 monitors and adjust the resolution for each monitor separately, up to 2560 x 1600
resolution per display. When 3D feature is enabled, up to 2 monitors are supported with a resolution of
up to 1920x1200.
n
You can copy and paste text and images between the local system and the desktop, up to 1MB. Supported
file formats include text, images, and RTF (Rich Text Format). You cannot copy and paste system objects
such as folders and files between systems.
n
PCoIP supports 32-bit color.
n
With optimization controls added in View 5, you can reduce bandwidth usage on the LAN and WAN and
achieve up to 75 percent bandwidth improvement.
n
PCoIP supports Advanced Encryption Standard (AES) 128-bit encryption, which is turned on by default.
n
For users outside the corporate firewall, you can use this protocol with View security servers or with your
company's virtual private network.
Client hardware must meet the following requirements:
n
x86-based processor with SSE2 extensions, with a 800MHz or higher processor speed.
n
ARM processor with NEON (preferred) or WMMX2 extensions, with a 1GHz or higher processor speed.
Microsoft RDP
Remote Desktop Protocol is the same protocol many people already use to access their work computer from
their home computer. RDP provides access to all the applications, files, and network resources on a remote
computer.
Microsoft RDP provides the following features:
n
With RDP 6, you can use multiple monitors in span mode. RDP 7 has true multiple monitor support, for
up to 16 monitors.
