Yep, you have the wrong cable..

[kevin-lucifer]

type-c to hdmi ,10gps cable , is this cable okay for 4k monitor@60hz? I'm confused by the standard.

And here is my hardware info:

[Floris497]

What exact cable? It's better to have DisplayPort.. most USB-C to HDMI don't support HDMI2.0 (it should specifically say HDMI2.0) but on the other hand MacOS kinda sucks with support for HDMI2.0 anyways...

[Floris497]

But u definitely don't need the patch on your machine :)

[kevin-lucifer]

here is my system info after patch, I got a UI Looks like: 1920 x 1080 @ 30 Hz

[kevin-lucifer]

my mac only have type-c and 3.5mm interface, it sucks...

[Floris497]

Yep, but talking about the cable, not the mac ;) also Dell is kinda shitty supported for mac on 4K.. can u send me link to specific cabel u have?

[kevin-lucifer]

I have no link about my cable, maybe I should buy one support hdmi2.0 myself. Btw,I find out some type-c to dp adapter on amz , are they pure digital signal, or d->a->d signal transfer in the adapter?

[kevin-lucifer]

Finally I decide to buy a type-c to dp cable. The best choice to save time and money. lol, thanks Floris.

[Floris497]

Yep, pure digital, if you want to wait a month there is pretty good options on AliExpr also

[kevin-lucifer]

Finally, @60hz lol.
