About FreeScreenTest
What This Site Does
FreeScreenTest provides browser-based tools for checking common display issues: dead pixels, backlight bleed, gamma, contrast, refresh rate, text clarity, HDR support, viewing angle behavior, and input responsiveness.
The tools are designed for quick checks on monitors, laptops, tablets, phones, and TVs. They are useful before returning a new display, adjusting monitor settings, or documenting visible screen defects.
How Tests Work
Most tests run entirely in your browser using fullscreen color patterns, animation timing, local browser APIs, and optional local history saved on your device. Results are educational and can vary by browser, operating system, graphics settings, and display hardware.
For warranty, return, medical, or color-critical decisions, always confirm results with the display manufacturer, retailer, or a proper measurement device.
Testing Method
The site prioritizes repeatable browser workflows: fullscreen patterns, visible defect marking, local history, report exports, and clear limitations. Test pages avoid accounts and do not upload monitor photos.
When a result affects a return or repair decision, use FreeScreenTest as a supporting record and compare it with the current policy from the retailer or manufacturer.
Editorial Approach
Guides and test instructions are written to explain practical display concepts in plain language. When warranty or manufacturer policies are discussed, treat them as general guidance and verify current terms in your region before making a claim.
Corrections are handled through the contact address listed on this site. Include the page URL and the specific statement that needs review.
