What is the white screen used for?
This is a pure #FFFFFF full-screen white display. Click the color to go fullscreen and use it as a clean, uniform white surface for testing, lighting and design.
- Monitor cleaning — a bright white background makes dust, smudges and fingerprints easy to see.
- Dead & stuck pixel check — dark dots stand out clearly against solid white.
- Brightness & uniformity — spot dim zones, tinting or clouding across the panel.
- Photography & video — use a second screen as a soft fill light or catch-light.
- Tracing & light box — a phone or tablet becomes an instant light table.
How to use it
Click anywhere on the white area to enter fullscreen, raise your device brightness to maximum, and run your test. You can also download a pure white image up to 8K using the resolution buttons above.
Frequently asked questions
Is this real white? Yes — every pixel is RGB (255, 255, 255), the maximum value for all three channels.
Can I use it as a light? Yes. On full brightness it works well as a soft, even light source for photos, video calls and close-up work.
What is the black screen used for?
This is a solid #000000 full-screen black display. It is the best background for spotting pixel faults and for checking how deep your display’s blacks really are.
- Dead & stuck pixel test — bright coloured dots are obvious against pure black.
- OLED / AMOLED black levels — true black pixels switch off completely, so you can judge real contrast.
- Backlight bleed & IPS glow — see light leaking from the edges of LCD panels.
- Burn-in check — faint ghost images show up more easily on a black field.
- Battery saving & ambience — a dark screen uses less power on OLED and makes a calm backdrop.
How to use it
Click the black area to go fullscreen in a dark room, then look closely for coloured dots (stuck pixels) or glowing edges (backlight bleed). Download a solid black image up to 8K with the buttons above.
Frequently asked questions
Why test on black? Dead and stuck pixels are far easier to see against black than against a busy image.
Is black better for OLED? Yes — OLED pixels turn off on true black, which saves power and shows perfect contrast.

Frequently asked questions
Can I use this for chroma key? Yes, for small subjects — light it flatly and keep your subject away from the screen to avoid green spill.
Why green and not blue? Cameras capture the most detail in the green channel, so green keys most cleanly.

Does blue show backlight bleed well? Yes — dark, saturated colours make edge light leaks stand out.
