Why does my webcam look grainy or blurry?

If your webcam looks grainy, blurry, pixelated, or low quality during your assessment, it can affect face detection, identity verification, and proctoring visibility. Grainy video is typically caused by insufficient lighting, camera sensor limitations, or incorrect camera settings. This guide helps you troubleshoot poor webcam quality and improve video clarity.

✅ Common Causes and Fixes

What Might Be Wrong	What You Can Do
Low lighting in the room	Sit in a well-lit room, preferably with natural light or a lamp facing you. Avoid backlighting.
Dirty or smudged webcam lens	Gently clean the webcam lens with a soft cloth before starting the test.
Webcam resolution is set too low	Close all apps using your camera, then restart the test.
Using a low-end or external webcam	Use your built-in laptop webcam if possible — they usually offer better quality for proctoring.
Background is too dark	Sit against a neutral-colored wall in a well-lit space to avoid contrast issues.
Internet speed is unstable	Graininess may appear if video is compressed. Run a speed test and ensure stable connection.
