Using GPOs, it is sometimes tedious to find the right values ​​for the Blast Extreme protocol.
So I decided to create a Windows utility (freeware) for administrators that allows to adjust the values ​​in real time.
The values ​​best suited to a specific context will save CPU/bandwidth resources and improve the user experience.
This tool can configure the following:

  • Codec type
  • Blast session bandwidth
  • Max frame per second (fps)
  • Size of Blast cache
  • Audio
  • Lossless compression
  • UDP protocol
  • Encoder CPU Controller
  • Quality of H.264, BlastCodec and Adaptive codecs (jpg/png)
  • HDR
  • High Color Accuracy
  • Blast settings export
  • DSCP
  • Nvidia vGPU license check
  • Display driver
  • Network stats & Blast stats

For information on codecs, see my article here


Export settings creates a text file with the configured values.
The Reset Blast button resets all Blast values ​​to default.
Transparent mode allows you to make adjustments while a video is playing to obtain more realistic values:


Blast Configurator runs locally in a Horizon session connected with the Omnissa Blast protocol.
For its operation, it is necessary to run it as Administrator.
