How do I perform a professional online dead pixel monitor test?

Our professional monitor test tool is designed specifically for dead pixel detection. By cycling through pure white screen, black screen, red, green, and blue color tools, you can easily identify stuck pixels, sub-pixel defects, or monitor backlight bleed issues.

Why use a bright white screen for light Zoom meeting backgrounds?

Standard office lighting often causes uneven camera shadows. By using a bright white screen for light as your primary front-facing light source, you create a large, soft white light that helps your webcam maintain a professional look and accurate skin tones.
