How to Check for Dead Pixels (and Stuck Pixels) on Any Monitor
A full-screen color test is the fastest way to find dead and stuck pixels. Here's how to run it properly, which colors to use, and what to do if you find one.
How to Fix a Stuck Pixel with a Color Flash (and When It Won't Work)
A stuck pixel is often fixable with a rapid red/green/blue flash. Learn the method that sometimes revives a stuck subpixel — and when to give up and claim warranty instead.
How to Test Screen Uniformity and Backlight Bleed
Uneven brightness, cloudy corners, and glowing edges are all signs of backlight bleed or poor uniformity. Here's how to check your panel like a reviewer.
Ways to use a White Screen
Trace or copy drawings onto paper
Fills your screen with maximum brightness so you can lay a sheet of paper over it and trace drawings or line art, or backlight a flipbook. No lightbox or tracing table required.
Spot dust and smudges while cleaning
A full-white display reveals physical dirt, lint, and oil marks on the surface, so you can see exactly where to wipe and check that the panel is clean afterward.
Soft ambient or reading light
Acts as a diffuser or reading light in dark rooms — bright enough to read or photograph by, without the harsh glare of a bare bulb.
Backdrop or fill for photos
A pure white screen doubles as a clean backdrop or soft fill light for product photos, portraits, and flat-lays. Download it as a PNG at 4K when you need a print-ready background.
White accent for a gaming setup
A white full-screen on a secondary monitor adds a clean, bright accent to a white gaming battlestation — perfect for photo-ready setups and streaming backgrounds.
Even webcam fill light for calls
Place a white screen on a second display or window just off-camera to bounce soft, even light onto your face — a free stand-in for a ring light.
Check your monitor for dead pixels
White (plus black, red, green, blue) full screens make stuck or dead pixels obvious. Cycle each color and scan for dots that don't change.
Makeup and selfie light
Hold a white screen near your face for shadow-free selfies and makeup application — instant beauty light with no setup.
Watch: White Screen Video
See a white screen fill edge-to-edge, then open it full screen on your own display.
What people use a full screen color for
White screen for lighting & photos
Use your phone or laptop as a soft white light source for selfies, product photos, or as a plain white background behind you on a video call.
Black screen to save battery & focus
A pure black screen uses less power on OLED displays and works as a screensaver, a distraction-free background, or a quick way to darken a room's ambient glow.
Zoom & video call backgrounds
Fill a second monitor or window with a solid color to use as a clean virtual-background substitute or to bounce even light onto your face.
Monitor & dead-pixel testing
Cycle through white, black, red, green and blue full screens to check for dead pixels, screen burn-in, uniformity, and color accuracy.
Green & blue screen for streaming
No physical backdrop? Display solid green or blue full screen on a spare monitor or tablet for quick chroma-key tests.
Downloadable color swatches
Export any color as a high-quality PNG at the exact pixel size you need for banners, thumbnails, or design mockups.
Frequently asked questions
How do I make my screen fully white?
Select the white tile, then press Go Full Screen. Your browser fills the entire screen edge-to-edge with a pure white background (#FFFFFF). Tap anywhere or press Escape to exit.
Can I download a color as an image?
Yes. Choose a color, pick a size preset or type a custom width and height in pixels, then press Download PNG. You'll get a lossless, high-quality PNG at exactly that size, rendered in your browser — nothing is uploaded.
Will this work on my phone?
Yes — it works on any modern phone, tablet, or desktop browser. On iPhone Safari, allow full screen when prompted for the smoothest edge-to-edge result.
Does this drain my battery?
A black full screen typically uses less power on OLED/AMOLED screens since those pixels turn off. White or bright colors use more power, similar to normal bright browsing.
