    This adapter DOES NOT support higher than 60hz on MacOS

    My Mac is capable of sending 4k at 240hz over HDMI or USB-4 / Thunderbolt — and yet this adapter caps the framerate at 60hz. WHY?????????

    It is truly unbelievable how they can charge 50 bucks for this thing with a straight face. These products look premium, but they DO NOT offer premium performance. They offer performance from 10 years ago. 4k60? What's even the point of putting HDMI 2.1 on these if you're going to limit the framerate to 60hz? So dumb, I will be returning the two that I bought
