Mine was like that with HDMI cable until I have my hands on the usb-c to mini-display cable

i only have type c ports here so everything goes trough a dock(and i tried 5 different ones so its not that)

if you have a usb-c to display port, give that a try without a dock usb-c hub -> usb-c display port only work on high end hubs (i have an alogic right in front of me know that works)

i tried 5 docks that work fine on any other laptop

If you’re trying to troubleshoot this, he’s saying to try it with just the cable so that you can identify that it’s the doc causing the issue and not your computer/os/monitor/cables. Remove variables and continue.

i tried 5 different docks, its not the dock…

all those variables work fine with any other laptopt, the macbook is the variable here.

They are telling you not to use ANY dock. Connect the cable to the monitor.

My Macbook drives a 144hz 4K display, so your issue is not your Mac unless you have an Intel based Mac.

Likely it is either the cable or user error.

This MacBook has 4 tpye c ports and that’s it. So you need some kind of adapter,no way around it. I tried and the results are the same.

Have you tried a direct USB-C to DisplayPort adapter or cable (not a dock)?

Yes,same thing

Weird, that seems to unusual based on people’s responses here and my quick Google.

I think it’s still solvable, in addition to the docks, there must be a cable or adapter that is causing the issue.

but why does it work fine with any other laptop?

I can’t answer that, despite that, there is a resolution. What model / year Mac is it?
