I don't quite understand how it works. My guess is that it doesn't actually perform any test itself, you're the one that is deciding whether the refresh rate is actually 60Hz. The big green "VALID" doesn't say you're monitor is at 60Hz, but that it is drawing at 60Hz to the frame buffer, and you can now observe the motions to decide for yourself whether it is smooth enough that the refresh is running at 60Hz?
- shurcooL 12y agoThat's exactly right. See the comment at the bottom of the article with two photos, it describes it in detail (confirming what you said).
- ojbyrne 12y agoThe comment at the bottom adds the key piece of information - you need a camera that you can set the shutter speed to 1/60th of a second.
