Well, my laptop is limited, and can't do 4K/60.
But if you're on an NVdia GPU, you have to go to the Nvidia control panel, go to change resolution, then customize, and then set a custom resolution. There, you can create your own resolutions anbd refresh. As long as you hit either the width or heigh of the display, you should be able to do any resolution. Since thisd is a 3840x2160 display, you can change to something odd like 3840x1234 if you wanted, and it would work. I'd advise to do 3840x1600 for the true ultrawide resolution (this is the ultrawide resolution of 3840 monitors sold today). You could even do stuff like 2160x2160. Again, it all works as long as the max width or height remains the same. One has to be maxed.
But yes, I can only do 4k/30 on my laptop, so I can only test stuff like 3840x1600 at 30hz.
I can at the very least do 1920 at any random height res like 810 for 1920x810 ultrawide. That's just 810p though, but it will look Blu-Rays in Ultrawide. No scaling.
Once I upgrade, I expect to do everything at 60hz.
You can see the black bars.
