Hey everyone,

I want to share something I built called ScreenBlack.

It started with a simple problem. I wanted a quick way to check a screen for dead pixels, color issues, or contrast problems. Most tools I found online were full of ads or made you download something just to run a basic test. That felt like too much work for something so simple.

So I built ScreenBlack. It runs right in your browser. No sign ups, no downloads, no ads getting in the way. You open it, run the test, and get your answer.

This is part of something I care about more broadly. I like building small, free tools that solve one problem well. ScreenBlack is one of them, and I plan to keep improving it based on what people actually need.

If you want to check it out, here's the link: [screenblack.site]

I would love to hear any feedback or ideas for what to add next.
