Should be absolutely perfectly totally fine. 4K might not be ideal since it will only do 30Hz. But 1080p is below the resolution of its own display and is really a quite low resolution these days, so it's fine.
It'll do 2560x1440 just fine, too.
3440x1440 checking in here. 60 Hz absolutely fine.

I Did nothing special. Also using the Apple adapter. Just plugged in and it worked. My monitor is the Dell though, not the LG.I have the 34" Curved LG 34UC97-S, which is also 3440x1440, and I'm only getting 30 hz (50 hz PAL, but I'm not in Europe where that might make a difference). There is no 60 hz option for me. I'm using the Apple multi-port adapter to HDMI, to the monitor. How are you making this work?

Only suggestion I have is to try a newer HDMI cable.
In another thread somebody just posted they were only getting 30hz until they changed HDMI cable and are now getting 60.Ohhh, that's right, the HDMI cable. I'm using the one that came with the LG. Maybe I'll buy a new HDMI 2.0 cable and give it a try. As I haven't done any gaming or video editing with this machine yet, I don't notice any drawbacks with only a 30 hz refresh rate. But of course, I would rather get 60 hz. if I can.
