Fixed: Logitech Brio webcam not showing 4k option
If you have a Logitech Brio 4k webcam and the highest resolution available is 1920 x 1080 and the choice for 4k is missing, then it might be the USB ports. I found the webcam has to be connected to a USB 3.0 port in order for the 4k video option to be available.
