Using a Black Screen to Improve Focus and Check Display Quality

[blackscreen]

When you’re studying characters, listening to tones, or navigating through language exercises for extended periods, visual overload can make concentration fade and even hide subtle imperfections on your display. A fullscreen black screen tool can help in two ways: first, it clears away all on-screen distractions so your eyes can reset between intensive study blocks; and second, it highlights uneven brightness, reflections, or dust on your monitor that might go unnoticed during regular use. By briefly switching to a plain black backdrop, you give your visual system a moment of rest and create an opportunity to catch display quirks before they affect your reading or note-taking.
