finally getting to be that time where I need a USB-C slot on my tower that I built back in 2017 so I started looking into expansion cards.

One thing I can't tell is how to tell if a particular expansion card supports the usb-c ports with DP-Alt mode for a 4k display if the need arises.

for exmple, had my eye on this one and I can't tell much if it does have that kind of support
