I have just got a U2720Q, it worked at 60Hz right away. But I am connecting over USB-C, with the provided cable.
What it did find off-putting is that Dell say they don't test with Macs, and thus can't support them, but they just assume that Appl follow the same specification they do. A bit weak, but the monitor does work fine.
