It’s extremely easy to tell the difference. I can’t tell you what’s wrong with their experiment as I don’t know exactly what they did, but they clearly fucked it. If you’re looking at a static image, you can’t differentiate 240Hz from 30Hz. You need a test that actually demonstrates the difference.
Remember that blind test on LTT where no one, including an esporty player, could reliably differentiate between 120 und 240 Hz?
I know it’s not exactly the most thorough experiment ever, but it’s all I needed to know.
