About ScreenTest.tools
A useful screen test starts with knowing what it can tell you.
Built for a closer look
ScreenTest.tools is a collection of browser-based utilities for displays, mice, and keyboards. The aim is simple: help you observe your device’s behavior with clear controls and concise explanations.
Honest about measurement
A web page sees browser events and timing, not every detail of your hardware. Screen dimensions are reported in CSS pixels. Frame-timing tools provide estimates, and color tests rely on your visual inspection.
Available checks
Browser timing, fullscreen colors, two original motion patterns, and mouse/keyboard event tools are available, along with browser-reported screen information. The Complete Monitor Test composes the display tools into an optional, local guided session.
