Where I work, everyone has 2 4k screens. You can use two cables to connect them, you know...
And every one of them has either put their scaling up to 150% or simply set them to 2k, because you cannot read a damn thing on them.
More than 4k is a theoretical need for a veeeery small market
Graphics cards only come with one HDMI port though. The LG OLED is popular for 4k screens because it ticks all the boxes and is much cheaper than equivalent gaming monitors, but that means it doesn't support dp.
And it means that you have to upgrade the graphics card just for the cable even if it is still relatively new. The point is that we shouldn't be held back by just a cable .
Graphics cards come with as many ports as the manufacturer wants them to. My home PC's GPU has two HDMI and two MiniDisplayPort. Also, there are cheap lossless adapters that will convert between MiniDisplayPort, DisplayPort, HDMI, DVI, etc, etc.
My graphics card has 3 HDMI ports and two DP ports... You cannot use all at once, but three screens are supported simultaneously...
I disagree with the more than 4K being a theoretical need thing but, regardless, where I work, every desk has a pair of 4K monitors that connect to the user's laptop via a single USB-C cable. That cable also connects a keyboard, mouse, gigabit ethernet and, depending on the desk, 10Gb ethernet, multiple cameras and conference audio. The cable also charges the laptop, of course. At the moment that's mostly done using USB-C docking stations, but we've started to deploy monitors that are USB-C native and can be daisychained together.
