Hardware requirements for PCoIP and VMware Blast

  • x86-based processor with SSE2 extensions, with an 800 MHz or faster processor speed.

  • Available RAM above system requirements to support various monitor setups. Use the following formula as a general guide.

    20MB + (24 * (# monitors) * (monitor width) * (monitor height))

    In general, you can use the following calculations.

    1 monitor: 1600 x 1200: 64MB
    2 monitors: 1600 x 1200: 128MB
    3 monitors: 1600 x 1200: 256MB

Hardware requirements for RDP

  • x86-based processor with SSE2 extensions, with an 800 MHz or faster processor speed.

  • 128 MB RAM.

Software requirements for RDP

  • For Windows 7, use RDP 7.1 or 8.0. Windows 7 includes RDP 7. Windows 7 SP1 includes RDP 7.1.

  • For Windows 8, use RDP 8.0. For Windows 8.1, use RDP 8.1.

  • For Windows 10, use RDP 10.0.

  • (Supported with View Agent 6.0.2 and earlier only) For Windows XP desktop virtual machines, you must install the RDP patches listed in Microsoft Knowledge Base (KB) articles 323497 and 884020. If you do not install the RDP patches, a Windows Sockets failed error message might appear on the client.

  • The agent installer configures the local firewall rule for inbound RDP connections to match the current RDP port of the host operating system, which is typically 3389. If you change the RDP port number, you must change the associated firewall rules.

You can download Remote Desktop Client versions from the Microsoft Download Center.

Video and graphics requirements

  • Latest video and graphics card drivers.
