In fact, the only services we know of that do are TrueConf and Vidyo. None of the usual suspects, including Skype, Zoom, or Google Meet support 4K right now. However, it's important to note that very few services support 4K today. If you want 4K support in your webcam, there are very few options right now. The Logitech Brio webcam's big selling point is its ability to capture video at a resolution of up to 4,096 x 2,160 pixels, which it does very capably, resulting in a crisp and richly detailed picture. You can also use the Logitech Capture app to record 4K video, and the app also offers the option to capture your screen with a second source and four different presets for picture-in-picture. If you want to crank the resolution up to 4K, just be aware that you need to connect via a USB 3.0 port and use software that supports a 4K resolution. It's a straightforward app that allows you to tweak the resolution, frame rate, exposure, field of view, zoom, anti-flicker, and a few other settings. If you want to dig into the camera settings, you need to install Logitech's Capture software. I used the Brio for video calls in Google Meet and Skype without installing anything extra and it worked fine. The webcam offers solid auto-focus, great color accuracy, and automatic white balance straight out of the box. Connect one end of the cable into a USB-A port on your PC or laptop and the other to the USB-C port on the webcam and you're good to go. The Logitech Brio is a plug and play webcam.
