The hub range is the farthest distance that the glasses can synchronise with the 3D Vision Pro Hub. You can reduce the hub range to limit the experience to a small group, or increase the range to include everyone in a large room.
To change the 3D Vision Pro Hub range
From the NVIDIA Control Panel navigation tree pane, under Stereoscopic 3D, select Manage 3D Vision Pro to open the associated page.
Click the Choose transceiver range arrow and then select the option that you want.
Short range - up to 2 meters (6.5 feet)
Medium range - up to 10 meters (32 feet)
Long range - the entire range of the hub.
Only the glasses that are within your selected range appear in the connected glasses box.
