The HDMI 4K requires a higher bandwidth cable.

Easier to show you

Maybe the source has to be 4K as well?

Or maybe its just broken?

Maybe there is a hidden setting you need to turn on?

Is your hdmi cable 4k capable

[jamartheg]

I think so, but I’m not 100% sure

[dean53AU]

You do need a different cable that can handle 4K, I'm pretty certain

Ig but it is able to get a signal for like a second before disconnecting

Actually nvm I checked online and it seems it is a 4K cable
