Quick verdict: Buy the Logitech Brio 4K if you want a proven 4K webcam with HDR, an adjustable field of view, and IR face sign-in for Windows Hello. Buy the Logitech MX Brio if image quality in difficult lighting is your priority, or if you want Show Mode for sharing what is on your desk and a built-in privacy cover. Both output 4K video; the MX Brio is the newer, more image-focused camera, while the Brio 4K keeps a convenience feature the MX Brio does not list.

The Core Difference: Established All-Rounder vs Newer Image-First Design#
The Brio 4K has been Logitech's flagship webcam for years, and it is still one of the most widely recommended. It records 4K at 30fps or 1080p at 60fps, uses RightLight 3 with HDR to balance backlit and mixed lighting, and lets you choose between 65, 78, and 90 degree fields of view so you can frame a tight head shot or include more of the room.
The MX Brio is the newer design. Logitech built it around a larger sensor with pixels it rates as 70% larger, paired with AI-enhanced image processing aimed at cleaner, more natural video in tough lighting. It also records in 4K UHD, but its emphasis is on image quality rather than on adding a long list of extra features.
Image Quality and Low Light#
For most calls in a reasonably lit room, both cameras produce sharp, professional video that is far beyond a typical laptop webcam. The difference shows up when lighting gets difficult. Larger pixels gather more light, and the MX Brio's AI enhancement is designed to manage exposure, noise, and skin tones automatically, so owners report it holds up better in dim offices and against bright windows.
The Brio 4K's RightLight 3 HDR still handles backlighting well, and it remains a strong performer. But if you often work in the evening, in a room without good lighting, or in front of a window, the MX Brio is the camera built for that situation.
Sign-In, Privacy, and Desk Sharing#
This is where the trade-off is clearest. The Brio 4K includes an integrated IR sensor that works with Windows Hello, so you can sign in to a Windows PC with your face. The MX Brio's spec sheet does not list IR face sign-in, so if that convenience matters to you, the older Brio is the one to buy.
The MX Brio counters with two practical additions. Its built-in privacy cover closes over the lens without a separate clip-on shade. And Show Mode lets you tilt the camera down toward your desk to share a sketch, document, or product during a call, with the camera designed to correct the image orientation automatically. For teachers, designers, and anyone who explains things on paper, that is a genuinely useful feature.
Audio and Connectivity#
The MX Brio uses dual beamforming microphones designed to focus on your voice and reduce background noise. That makes it a more capable all-in-one option if you do not use a separate headset or microphone, though a dedicated mic will still sound better than either webcam.
On connections, the MX Brio uses USB-C, while the Brio 4K is listed with USB-A / USB-C connection. Either way, both cameras need a capable computer and a fast USB port to deliver full 4K quality, so check your host machine before relying on 4K output.
Who Should Buy Which#
Choose the Logitech Brio 4K if you:
- Want to sign in to Windows with your face via Windows Hello
- Like having three field-of-view presets to frame your shot
- Work in a well-lit room and want a proven, established 4K camera
Choose the Logitech MX Brio if you:
- Often work in dim light or with a bright window behind you
- Want Show Mode to share documents or objects on your desk
- Prefer a built-in privacy cover and better onboard microphones
Frequently Asked Questions#
Is the MX Brio worth it over the Brio 4K?#
Yes, if image quality in difficult lighting is your top priority, or if you would use Show Mode and the built-in privacy cover. The MX Brio's larger pixels and AI image processing are designed for cleaner video in dim and backlit rooms. If you rely on Windows Hello face sign-in, the Brio 4K is the better buy because the MX Brio does not list an IR sensor.
Does the MX Brio support Windows Hello?#
The MX Brio's specifications do not list an IR sensor for Windows Hello face sign-in. The Brio 4K does include integrated IR for Windows Hello, so choose it if that feature is important to you.
Do both webcams record in 4K?#
Yes. Both output 4K Ultra HD video. The Brio 4K records 4K at 30fps or 1080p at 60fps. Both need a modern computer with a fast USB connection to deliver full 4K quality.
Which webcam is better for streaming and video calls?#
For everyday video calls in a well-lit room, both are excellent. For streaming or calls in challenging light, the MX Brio is the stronger choice thanks to its larger pixels and AI image enhancement, and its beamforming microphones are a step up if you do not use a separate mic.
The Verdict#
The Brio 4K remains a dependable 4K webcam with HDR, flexible framing, and Windows Hello face sign-in, and it is the right pick for Windows users who value that convenience. The MX Brio is the better camera for image quality, especially in tricky lighting, and its Show Mode, privacy cover, and beamforming mics make it the more complete modern setup.
