In addition, NVIDIA highlights display-related updates that improve daily usability. The company says the update improves monitor and TV compatibility, including better handling of multi-monitor setups plus non-native resolutions and refresh rates.
NVIDIA notes DGX Spark now supports Bluetooth audio devices such as headphones and headsets, and it adds the ability to disable Wi-Fi and Bluetooth at the UEFI level for locked-down environments. NVIDIA’s UEFI documentation notes this toggle disables both wireless LAN and Bluetooth together.
