Not sure about multiple monitors

Most usb-c ports with DP alt mode support up to 1 monitor at 4k@60Hz, or 2×1080p@60Hz, and I believe 2×1440p@30Hz. It comes down to bandwidth, so I think that as long as you’re fine with one monitor running at a slower refresh-rate or lower resolution, you can have your primary screen displaying in high-res.

Of course, you have to also take into consideration the GPU performance, running higher resolutions will usually degrade performance!
