You can check for dead pixels, backlight bleed, stuck pixels, and even OLED burn-in with solid color tests (black, white, red, green, blue).

It’s lightweight, works on laptops, phones, and TVs, and has fullscreen mode for more accurate results. I made it mainly for personal use, but I thought others might find it handy too.
