Blast Extreme support on Windows 10

Horizon 7.7+ needed.

Windows 10 versions before 1803 (even the Enterprise editions) do not include the necessary API to allow integration and usage of Blast as a display protocol. The restriction is that Microsoft only exposes the required API in Win 1803 and later and in Enterprise Edition only (see below in limitations).

With some versions and with earlier versions of Horizon 7, Blast is available, but this was done in a insecure manner and physical monitor is mirrored on the PC. To avoid mirroring the monitor, RDP is recommended.

Limitations & considerations

  • 3D apps not supported in Blast Extreme. Use PCoIP with Tera-card (like Teradici Tera2240);
  • GPU Hardware h.264 encoding on consumer GPUSs - but h.264 encoding of Blast packets will be on CPU;
  • All power saving options should be disabled (unless Wake-on-Lan is active);
  • No remote mechanism of reset in case of OS crash;
  • OS Windows 10 1903 / 1909 require Horizon 7.12 agent;
  • OS Windows 10 older than 1803 will lock screen during Blast session;
  • OS Windows 7 does NOT support Blast:
  • RDP not supported over HTML.
  • No labels
