Why Logitech Brio 4K Looks Overexposed in Browser Tests (And Fixes)

RightLight is Logitech's own auto-exposure and lighting correction technology, designed specifically to intelligently brighten faces and compensate for challenging lighting like a bright window behind you — genuinely useful in exactly those difficult conditions it targets, adjusting exposure more aggressively than a simple, generic automatic exposure system would.

The Brio also supports HDR (High Dynamic Range) capture as a real, marketed feature, capturing a wider range of light and dark detail in a single frame than standard capture — while genuinely valuable for scenes with significant contrast, it can occasionally push overall brightness further than a well-lit, evenly balanced room actually needs.

The specific combination of both features running simultaneously, in a bright test environment that doesn't actually need this level of aggressive compensation, is what produces the overexposed look this describes — both features doing exactly what they're designed to do, just applied to conditions that don't call for that much correction in the first place.

Step 1: Open Logitech's official camera settings software

(Logi Options+ or the Brio's specific settings app, depending on your exact software version).

Step 2: Locate the RightLight setting

And try turning it off or reducing its intensity as a direct test.

Step 3: Check for a separate HDR toggle

And try disabling it as well.

Step 4: Test with both disabled

Then re-enable one at a time to identify which specifically caused the overexposure in your particular lighting setup.

Step 5: Manually adjust brightness and exposure directly

If your software offers manual controls, for more precise control than either automatic feature provides on its own. ↑ Confirm improved exposure with the widget above.

How do I reset the Windows Camera app itself?

Go to Settings → Apps → Installed apps, find Camera, open its three-dot menu, and choose Advanced options → Reset. This clears the built-in Camera app’s own cache and settings without uninstalling it, which can fix a stuck, frozen, or permanently black preview even when the underlying device and driver are both working correctly. It only resets that one app — not your camera driver, and not other applications that use the camera.

Could my antivirus be silently blocking my camera?

Many third-party security suites — Bitdefender, Kaspersky, Norton, and ESET among others — include their own webcam-protection feature that runs independently of Windows’ own privacy settings. That means Windows can show camera access as fully permitted while the antivirus software blocks it anyway, at a layer Windows has no visibility into. Check the antivirus program’s own settings, usually under a Privacy, Webcam Protection, or similarly named section, and confirm your browser or conferencing app is on its allow-list.

How do I re-enable my camera in Device Manager if it's disabled?

Right-click the Start button → Device Manager, expand Cameras or Imaging devices, and look for a greyed-out icon or a small down-arrow badge. Right-click that entry and choose Enable device. This is a different action from updating a driver — a disabled device won’t respond to any other fix until it’s explicitly re-enabled here first, so it’s worth checking before assuming the problem is a driver or a permission.

Is Windows' own camera privacy toggle blocking access, separately from anything else?

Windows keeps a system-level camera permission at Settings → Privacy & security → Camera, completely separate from Device Manager, the Camera app, and any antivirus software. This one screen has a master Camera access switch plus a per-app list beneath it — both need to be on. It’s worth checking directly, since a camera can show as fully enabled and working in Device Manager while this toggle silently blocks every app from reaching it.
