What the Brio 4K should deliver
Logitech lists the Brio at 4K and 30 fps (up to 4096 × 2160), 1080p at 60 fps or 720p at 90 fps, with autofocus, 5x digital zoom, three fields of view (90°, 78° and 65°, set in Logi Tune), RightLight 3 with HDR, and an infrared sensor for Windows Hello. Its spec sheet (model V-U0040) adds one limit that matters here: on USB 2.0 the Brio is limited to 1080p at 30 fps. The table above holds one mode at each size: the page opens the camera at 3840×2160 and 30 fps, and Check switches to 1080p at 60 or 720p at 90 and measures again.
When the Brio stops at 1080p
If the 4K row shows ✕ 1920×1080 instead, the camera is telling you it can’t get 4K through. Logitech’s list of 4K requirements:
- A USB 3.0 port. USB 3.0 carries 5 Gb/s, USB 2.0 only 480 Mb/s, too little for 4K. A hub, dock or extension cable in between counts too: the slowest link sets the speed.
- An app that supports 4K, sometimes with extra codecs. This page asks for 4K directly, so a pass here and 1080p in your app means the app is the limit.
- A 4K monitor with its drivers, and Windows 10 or later: Windows 7 stops at 1080p/30.
- Current USB host controller drivers.
USB 2.0 holds back the frame rate too, so if the 4K row came back as 1080p, a 1080p row stuck at 30 fps has the same cause: fix the connection before you add light. The summary under the table says so when it sees both.
Monitor hubs deserve a special mention. Dell documents a Brio stuck at 1080p on some Alienware and Dell laptops (Alienware x14 R2, Dell G15 5530 and G16 7630) plugged into a Dell monitor: with the monitor’s USB-C Prioritization set to High Resolution, its USB hub runs at USB 2.0 speed. Switching it to High Data Speed, or plugging the camera straight into the laptop, brings 4K back.
Frame rate and light
Once 4K arrives, the 60 and 90 fps rows need plenty of light, because each frame gets at most a sixtieth or a ninetieth of a second of exposure. If a row reads ≈ slower than listed, add light in front of you and check it again. For 90 fps, use Chrome or Edge: they count the frames the camera sends, while other browsers count frames as the screen shows them, at most one per refresh, so they can’t confirm 90 fps on a 60 Hz display. The Resolution scan also shows which sizes the camera delivers natively and at what frame rate.
Logitech uses the Brio name for several webcams, and the Brio 300 series, for example, is 1080p at 30 fps. Testing a 1080p Logitech? The C920 test and the C922 test follow the same method. Check the Brio’s microphones with the microphone test.
