What I do have with me is a hdmi to hdmi cable and this cable that I connect the two monitors to my laptop at the moment. I assume this wouldn't work since its not hdmi 2.0?

I have a Dell U2720Q monitor that accepts HDMI 2.0, DisplayPort 1.4 and USB-C. I use USB-C because the monitor acts as a hub for a range of peripherals (keyboard, mouse, webcam, speakers, etc.etc ...

Because I have an older laptop, I had to use an HDMI cable that wasn’t included to connect to the monitor since USB will translate data—but not video—to most laptops made before 2017.

This 43-inch Dell monitor is actually four monitors in one The 43-inch Dell P4317Q can let you use four different computers (or game consoles, or cable boxes) at the same time.

HDMI 1.0 can only transfer a maximum resolution of 1080p at a rate of 60Hz and supports eight audio channels. 1.1 and 1.2 can do 1440p, but only at 30Hz.
