UFO Test: Multiple Framerates

TestUFO: Where Your Monitor Gets Put Through Its Paces

Ever wondered if that fancy 144Hz screen you bought actually delivers? TestUFO is the answer. Run by the folks at Blur Busters, it's a free browser-based playground packed with motion tests that reveal what your display can really do. No downloads, no fuss. Little animated UFOs zip across your screen at different frame rates, and suddenly the difference between 60Hz and 240Hz stops being marketing fluff and becomes something you can see with your own eyes. Gamers swear by it, reviewers lean on it, and hardware nerds treat it like scripture.

The main page fires up the classic frame rate comparison straight away: rows of UFOs gliding along at different speeds so you can spot stutter, blur, or skipped frames instantly. Up top sits a dropdown stuffed with other tests, everything from ghosting and persistence checks to frame skipping and moving photo demos. Your detected refresh rate is shown right there too, along with a verdict on whether your browser is keeping up. Handy links point back to Blur Busters for deeper reading. Simple layout, serious utility.
