What the C920 should deliver
Logitech lists the C920 PRO HD as 1080p at 30 fps, or 720p at 30 fps, with a five-element glass lens, autofocus, a 78° diagonal field of view, two microphones for stereo sound and automatic light correction. The C920s spec sheet adds the details: USB 2.0, a 5-foot cable, video from 360p to 1080p, and a privacy shade.
The table above holds those two modes. This page opens the camera at the first, 1920×1080 at 30 fps, and fills in its row once it has measured a few seconds of video. Press Check on the 720p row to switch modes and measure again.
Reading the result
- ✓ means the camera delivered the listed size at close to the listed frame rate.
- ≈ slower than listed means the size is right but frames are missing. Most often this is light: a webcam that needs a longer exposure in a dim room can’t fit 30 frames into a second. Turn on a lamp in front of you (not behind), and the row should recover within a few seconds.
- ✕ … instead means the camera sent another size. Close other apps that have the camera open, plug it straight into the computer, and try again. Logitech’s own C920 article on 1080p calls warns that with many applications running you may not get 1080p even on a fast enough processor, so close what you don’t need.
If a yellow note says the open camera isn’t a C920, pick it in the Camera list: a laptop’s own camera often opens first.
The C920’s own features
The C920 has autofocus, so if the sharpness line in the quality score says the picture is soft, give it a moment to settle and wipe the glass lens. It also has automatic light correction, which Logitech calls RightLight 2. On a C920s, a black picture while the camera’s light is on usually means the privacy shade is closed. Logitech’s software for the C920 is Logi Tune for video calls and G HUB for gaming.
Check the C920’s stereo microphones with the microphone test. Streaming at 60 fps needs a different camera: see the C922 test, or the Brio 4K test for 4K.
