Video quality test
Find out the highest resolution your connection can stream without stalling. We test rung by rung until we find the maximum it holds.
We play real video at each bitrate and measure the actual playback — we don’t estimate it from your download speed. That’s why it can differ: many providers treat video differently from the rest of your traffic.
This test downloads real video: it uses about 17 MB. Keep that in mind on mobile data.
