Complete Screen Test Checklist
Follow our structured 10-point inspection guide to verify the performance, quality, and health of your digital display panel.
Dead Pixel Sweep
Check for non-responsive subpixels showing up as static black dots on solid colors (White, Grey, Red, Green, Blue).
Run Dead Pixel Test →Stuck Subpixel Check
Locate subpixels locked in an open state, appearing as static Red, Green, or Blue spots on dark backgrounds.
Run Stuck Pixel Test →Bright Pixels / Hot Pixels
Spot pixels where all channels (Red, Green, Blue) are stuck active, appearing as white dots on dark backgrounds.
Scan for White Spots →Brightness Uniformity
Observe uniform colors (specifically White and Medium Grey) to check for dark shadow lines, cloudy spots, or dim zones.
Check Screen Uniformity →Backlight Bleeding
Inspect screen edges on pure black backgrounds in a dark room to locate light leakage escaping the physical panel border.
Run Backlight Bleed Test →IPS Glow Characteristics
Move your head slightly to check if glowing corner patches shift or disappear (normal IPS behavior vs permanent bleed).
Evaluate Corner Glow →Resolution Mapping
Verify viewport dimension properties, Device Pixel Ratio scaling, and check if OS scaling matches native parameters.
Verify Resolution Specs →Estimated Refresh Rate (Hz)
Confirm browser animation render speed and check if your monitor runs at its advertised refresh rates (60Hz, 120Hz, 144Hz+).
Check Refresh Rate →Color Behavior & Gradients
Scan 256-level black-to-white gradients and primary color sweeps to inspect for banding, missing shades, or color tint shifts.
Motion Rendering Test
Run the UFO horizontal speed tracker to assess ghosting trails, screen tearing, and basic panel response responsiveness.
