White display guide
Build a precise white test screen
This dedicated white page combines a uniform fullscreen field with exact color and resolution controls for closer display inspection.
Set the white point
Keep pure #FFFFFF or enter a softer near-white value when full brightness is uncomfortable in your room.
Inspect or export
Launch fullscreen for a visual check, or select dimensions and save a white PNG for later use.
White screen tasks
Practical jobs for a bright panel
Find dust and marks
A bright uniform background makes fingerprints, dust, and streaks easier to locate before carefully cleaning a display.
Look for uneven areas
Scan the screen from edge to edge for visible dim spots, tint shifts, or pixels that contrast with the white field.
Backlight a paper layer
Use the panel gently beneath tracing paper, film, or a translucent craft piece when a lightbox is unavailable.
Compare nearby displays
Open the same white field on two screens to notice broad brightness or color differences without treating it as calibration.
