Screen Issues

browser tool to detect dead pixels and screen defects

What it does

Screen Issues is a lightweight browser-based tool that helps you quickly check and diagnose common display problems such as dead pixels, backlight bleed, bright spots, and uneven brightness. Most users only notice screen issues when something “looks wrong,” but it’s often hard to tell whether it’s a real hardware problem or just normal display behavior. Screen Issues solves this by providing simple full-screen color tests that make defects easy to identify within seconds. No installation.

I built a frontpage for personal blogs▲783
With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
