—— bit Browser reportA dark field makes edge light and broad glow easier to notice on an LCD. Compare the same area at the same brightness and viewing angle before deciding whether it affects ordinary viewing.
Use a darkened room when inspecting a black field, then return to your normal lighting as a second check. Record brightness and picture mode rather than automatically choosing an extreme setting. Close reflections and clean the surface before looking around the edges.
Observe the center, corners and edges while keeping the camera and your eyes near the usual viewing position. A glow that changes as you move is different from a patch that stays fixed. This distinction is useful evidence, but a browser cannot diagnose the mechanical cause of an individual bright area.
Camera exposure can exaggerate faint light on a nearly black screen. Keep photographic settings consistent and compare the photographs with your visual impression. A physical problem will not be captured by a system screenshot. Check model-specific support guidance when deciding what action to take.
Keep angle and camera exposure fixed to distinguish IPS glow, reflections and persistent bright patches.
Use normal display brightness in a dim room.
Face the screen and inspect its corners and edges.
Return to everyday content to judge the impact.
Patterns support visual inspection. Quantitative color accuracy, brightness, gamut coverage and response time require appropriate instruments and methods.
Reflections, angle-dependent glow and persistent backlight leakage are different. Move your viewing position and recheck in normal conditions.
Automatic exposure can exaggerate bright patches. Use fixed exposure and compare with direct observation.
No. It provides display test patterns and browser information. Screen anomalies that persist at the same position need visual inspection and, when needed, professional assessment.
Open the patterns and guides for your device. True full screen and touch depend on the browser; an immersive page preview remains available when full screen is unsupported.
No installation is needed. Patterns, calculations and interactions run locally in your browser; theme preferences stay on your device.
Rule out dust, reflections and display settings. Repeat under the same conditions, photograph defects that remain in the same screen position and check the device warranty policy.
