Screen Test Online
The PCHardwareTest screen test online provides browser-rendered colors and patterns so you can visually inspect a laptop screen or external monitor. It is designed for practical visual checking rather than low-level panel measurement.
What this screen test online can check
- solid-color display checks
- pattern display checks
- fullscreen inspection
- visual pixel inspection
- basic display uniformity observation
A website can make display defects easier to see, but it cannot electrically verify a pixel or measure internal panel electronics. A suspected defect should be compared under several colors.
How to screen test online
- Open Screen Test Online and enter the fullscreen view when prompted.
- Move through the available solid colors and patterns.
- Inspect the display closely for spots that do not change with the surrounding color, uneven areas or obvious visual artifacts.
- Exit fullscreen and repeat with a clean screen if you need a second visual pass.
What the browser can and cannot tell you
A website can make display defects easier to see, but it cannot electrically verify a pixel or measure internal panel electronics. A suspected defect should be compared under several colors. The goal is to make the browser-visible behavior easy to verify without pretending that a web page can inspect every internal hardware component.
