I use DP to USBC cables (no adapter) on my Macbook Pro M1 when connecting to my Dell 4K displays. Works well.

So, if I read you right, I can just get Thunderbolt 4 cables and they will work with pretty much everything (as of this writing)?

Do you know if USB4 plugs are backwards compatible with USB-C/USB3? Or are the pins different?

I bought this and works great a well with 4k 144hz
