A pure bright white screen makes every speck of dust, smudge and fingerprint visible — perfect for cleaning a laptop or monitor. Open the white screen tool, go fullscreen, and wipe with a microfiber cloth top-to-bottom.

Any pixel that doesn't show pure #FFFFFF on a fullscreen white background is stuck-off or dead. Pair with our black, red, green and blue screen tools to catch every type.

A bright white screen at full brightness makes a free, soft light source. Great for jewelry, food and product photography on a budget. Want even more output? Stack two laptops or a tablet alongside.

No projector screen? A white sheet for projector screen use works surprisingly well — but pull it taut to avoid wrinkles, and stick to matte cotton over polyester to reduce hot-spotting. For a quick test, project onto a fullscreen white wall image to find the brightest spot in your room.

Phone or tablet brightness on a white screen at 100% is roughly 400–800 nits — enough as a reading light during a power outage, or to find dropped earrings under a sofa.

On a video call when someone shares your screen by accident? A fullscreen white window hides everything underneath in one click.

Aim a phone showing a bright white screen at the shadow side of a portrait subject — it's a free reflector. Works best within 1m of the subject.

A white screen full-brightness on your phone is brighter than the LED torch on most older models. Slide it under a sofa to find a missing earring, AirPod or USB cable.
