Screen Guides: Tests, Fixes and How-To Articles

Black Screen Online shares simple screen guides to help you use and check your display. Learn how to test it for dead pixels and light bleed, what each color screen is good for, why a screen goes black on its own, and how to use the clocks and timers. Each guide ends with a free tool you can open in one click.

New guides are on the way. You can try our free screen tools below.
