About DeadPixelCheck.com
A free, browser-based pixel-testing tool and editorial hub for everyone who cares about the quality of their screens.
What We Do
DeadPixelCheck.com gives you a fast, accurate way to find dead and stuck pixels on any monitor, laptop, phone, tablet, TV, or handheld console — no downloads, no accounts, no tracking of what you test. The tool runs entirely in your browser and cycles through the solid colors that make display defects easiest to spot.
Beyond the tool, we publish practical guides on display technology: manufacturer warranty policies, repair techniques, panel comparisons (IPS vs VA vs TN, OLED vs LED), and advice for when to return versus repair a screen.
Who Operates This Site
Operator: Liquid Amber Partners LLC (a Wyoming limited liability company)
Registered Address: 30 N Gould St Ste N, Sheridan, WY 82801, USA
Contact: support@gammaflux.io
Liquid Amber Partners LLC is an independent operator of a small portfolio of consumer tool sites. We have no relationship with any monitor manufacturer, and we don't accept payment for article placements or editorial direction.
Editorial Approach
Every article on this site is written to help real users make real decisions about their displays. We test policies against manufacturer documentation before publishing, link to primary sources where possible, and update articles when policies change.
Articles may link to products on Amazon and other retailers through affiliate programs (see our Privacy Policy and Terms of Service). Affiliate revenue helps keep the pixel-testing tool free for everyone. Product recommendations are selected on the basis of technical relevance to the article topic — not the size of the commission.
How the Site Is Funded
DeadPixelCheck.com is funded through two sources: (1) display advertising served by Google AdSense, and (2) affiliate commissions from Amazon Associates and similar programs. We do not sell your personal information. See our Privacy Policy for detail on advertising cookies and opt-out options.
