>Macs (at least the good old trashcan) also can't do 4k@60Hz over HDMI I cannot speak for the old trashcan ones (assuming this is a reference to the desktop Mac Pro), but this has not been true for at least the last few generations of Macbook Pro laptops. You just gotta make sure your cable supports HDMI2 and that you aren't using one of those multi-port dongles. Finding a cable/adapter that allows 4k@60hz on macbooks might be tricky though (as evidenced by a lot of threads on the topic I found on reddit and Apple forums). I lucked out, and the first cable I bought (direct USB-C to HDMI, not a dongle) ended up working swimmingly with no issues.

Do you have the manufacturer’s name and the model number for that cable, or an Amazon link? I’ve been having some trouble with my MacBook Air and a new monitor that I recently bought, and I suspect that the cheap dongle I am using is partly to blame. In particular, when my MacBook Air goes to sleep, and I then later wake it up, the new external monitor does not turn back on. And to make matters worse, the monitor does not even respond to the on/off button on the monitor in this state. So I then have to physically unplug the monitor power cable, which is damn annoying, because the outlet is hard to get to. Weirdly however, my old monitor had no such problem. I did notice, however, that even though the dongle is for USB-C to HDMI, the MacBook Air thinks that it is connected via DisplayPort. Since I’d already put the old monitor away I didn’t check to see if that used to be the case there as well, but I am thinking that conceivably this could have some connection with the inability of the new monitor to wake up. Right now I am not at home, and haven’t been for a while, but as far as I remember, I ended up telling the MacBook Air to never turn off the monitors. However, that is not a good workaround. The MacBook Air is a 2018 model. The monitor is a Svive 34" Curved Pyx 34C801, with 3440x1440 resolution and up to 144 Hz refresh rate. I also connect my desktop computer to this monitor, which is why I bought a monitor with such high refresh rate since my desktop computer is able to deliver video at such high refresh rate even at full resolution. When only the desktop computer is connected, the monitor wakes as it should when I turn on the desktop computer. But when the MacBook Air is connected, whether alone or alongside the desktop, the MacBook Air can not wake the monitor again after the monitor has been put to sleep by the MacBook Air. So i would like to order a cable like the one you are using and see if that will help me avoid this problem.
