VIVE Hub

• Update the driver of your graphics card to the latest version.
• If you've recently performed a BIOS update on your PC (for example, HP BIOS and System Firmware v. 02.13.03 Rev.A Mar 3, 2024), check if the NVIDIA hardware codec has been disabled. If the codec is disabled, enable it again. If you can't enable the codec, you'll need to roll back the BIOS version.

• Check the Requirements and see if your computer's GPU meets the minimum requirements.
• If your laptop is using an NVIDIA graphics card, make sure the VIVE Streaming server is running on dGPU instead of iGPU.

  Open the NVIDIA Control Panel, and then go to Manage 3D settings. On the Global Settings tab, set Preferred graphics processor to High-performance NVIDIA processor.

• The VIVE Streaming driver may be blocked by SteamVR. In SteamVR settings, go to Startup/Shutdown. Show the Advanced Settings, and then click Manage Add-Ons. Make sure VIVE Streaming is not blocked.
• VIVE Streaming is not registered properly to SteamVR. Close SteamVR, and then restart VIVE Streaming.
