If you find yourself browsing threads or reading long posts and notice your eyes feeling tired or the display looking hazy, it’s often worth checking the screen itself before tweaking every setting. Dust, fingerprints, or small smudges on the monitor can subtly impact clarity without being obvious at first. A simple way to test how your display is performing is to use this website — it fills your browser with a plain dark background so you can easily spot glare, uneven brightness, or lingering marks that might affect how content looks. It’s a quick, no-install approach that helps you stay comfortable and focused during extended online sessions.
