Laptop Screen Test
This free laptop screen test helps you check for dead pixels, backlight bleed, color banding, and touch issues on Windows and everyday laptops. Run it in your browser with no software install.
This page uses easy wording so anyone can follow along. You do not need special skills. Look at the screen, tap where needed, and note what looks wrong on your laptop.
Use this check when buying a used laptop, after travel, or before returning a new device. Screen faults are easier to prove with a clear browser test than with a desktop wallpaper.
What this laptop screen test helps you find
A cracked glass is easy to see. Many costly display faults are not. These simple checks make dead pixels, touch faults, tint, and burn-in easier to notice.
Dead pixel scan
Full red, green, blue, black, and white screens make bad pixels easy to see.
Backlight bleed
Black screens reveal bright corners and cloudy glow on IPS panels.
Color uniformity
Look for tint shifts from one side of the screen to the other.
Gradient banding
Smooth color fades should not look striped or blotchy.
Touchscreen mapping
On 2-in-1 laptops, check taps and swipes across the full panel.
After hinge stress
Retest if the lid was bent, dropped, or pressed hard in a bag.
How to use this laptop screen check
- Clean the display. Dust and fingerprints are often mistaken for dead pixels.
- Use a darker room for black tests. Backlight bleed and burn-in show up better in low light.
- Use normal light for color tests. Bright windows can hide tint problems.
- Cover every edge in the touch test. Corners and camera cutouts fail first after drops or repairs.
- Write down what you see. Note dead pixels, dead zones, tint, glow, or image shadows.
Common laptop screen problems
People search for a laptop screen test, dead pixel checker, touch screen test, and OLED burn-in test for the same reason: a bad display can ruin an otherwise good device.
Bright corner glow
Common on IPS laptops and worse in a dark room.
Stuck pixel
A tiny always-lit color dot that stays in one place.
Pressure spots
Cloudy marks from bag pressure or lid force.
Uneven whites
One side looks warmer or cooler than the other.
When you should run a laptop screen test
Before buying used
Sellers can hide faults with bright wallpapers. Solid color screens make defects obvious.
After a drop
Touch can fail even when the glass still looks fine.
After screen repair
Confirm the new panel has no dead pixels or dead touch zones.
Before selling
Know the real condition of the display before a trade-in.
For warranty proof
Clear notes and screenshots help explain what is wrong.
When colors look odd
Tint, banding, and burn-in are easier to judge on test screens.
