Laptops Which Support 5120x1440 at Native (Not Low) Resolution?

Hi,

I'm interested in purchasing a new Mac laptop. However, I want it to be able to push to my Samsung C49RG90, a monitor with a resolution of 5120x1440p and a maximum refresh rate of 120Hz.

I've seen that a number of laptops are listed as capable of "6K" content, but I've also seen that a number of users here have had significant issues trying to push this resolution. Some are finding their computers only capable of pushing this at "low resolution", which will not be sufficient.

Which of the current range of Macs, if any, can push 5120x1440p at a minimum of 60Hz, and preferably at 120Hz?

Thanks in advance!
