I have a Samsung G9 super ultrawide that supports 5120x1440@240Hz (with Display Stream Compression) over DisplayPort 1.4 and 5120x1440@120Hz over HDMI 2.0. The tricky part is I have 3 laptops that I use regularly and I am trying to find a dock or cable solution that makes using the 3 laptops easy. The Samsung G9 is amazing btw and if you have the money, I can highly recommend it for immersive first person gaming.
The Samsung G9 has 2 Display port inputs along with a single HDMI input.
