Troubleshooting: Hardware acceleration issues - Security Center 5.6

Security Center 5.6

Security Desk can detect and use compatible hardware to accelerate video decoding. Hardware acceleration provides enhanced performance, especially when viewing multiple high-definition H.264 streams.

What you should know

For information on recommended video cards and performance benchmarks, see the Security Center 5.6 System Requirements document.

NOTE: Security Desk does not support hardware acceleration under Windows XP.


  1. To optimize the operation with NVIDIA video cards, make sure of the following:
    • The video card is of a compatible model.
    • The monitor or projector used to display video is plugged into this video card.
    • The installed driver is the latest available from NVIDIA's official web site.
  2. To optimize the operation with Intel Quick Sync, make sure of the following:
    • Your CPU supports Quick Sync (see
    • The integrated video card on your CPU is of a compatible model.
    • A monitor is plugged into the motherboard's integrated output.
    • The Intel integrated graphics is enabled in the BIOS.
    • The installed driver is the latest available from Intel's official site.
    NOTE: On high performance computers, NVIDIA GPU decoding works better when Quick Sync is disabled.
  3. To troubleshoot problems with multiple screens and multiple GPUs, make sure of the following:
    • If "SLI" mode is available, disable it.
    • If you have multiple NVIDIA video cards, connect each monitor to a different card to use them in parallel.
    • If you have video cards using different drivers (AMD, NVIDIA, Intel), set a monitor connected to a NVIDIA card as the primary monitor.
    • If both integrated and discrete video cards are available, and if your NVIDIA video card meets the recommended requirements, disable your integrated video card in the BIOS. Having the integrated card available actually hinders the discrete video card performance.
    • On laptops using NVIDIA OPTIMUS technology (combined Intel and NVIDIA GPUs), you need to launch each video intensive application (Security Desk, Genetecâ„¢ Video Player, and so on) a first time, after you installed Security Center, to allow the application to register itself as an application that requires NVIDIA GPU. After the initial run, the application will always use the NVIDIA GPU thereafter.
