About Lucas
Lucas builds and runs Screentific. He works in digital marketing, web analytics and search. He started Screentific to put the most useful full screen tools in one fast place: plain color screens, screen lights, screensavers and, above all, proper screen tests that anyone can run in a browser.
How the guides are written
- Checked against primary sources. Facts come from display manufacturers, published standards and technical references, listed at the end of every guide.
- Honest about limits. If a browser test cannot measure something, or a fix only works sometimes, the guide says so.
- Testable. Every guide links to a free test on this site, so you can check your own screen instead of taking our word for it.
- Updated. Each guide shows the date it was last checked.
