So I have a doubt regarding the resolution and image quality of Series S.

I'm running the diagnosis of the console "4k TV Details" and all checkboxes are green.

I have a TCL r646 and it's enabled the HDMI mode to 2.1 in the menu.

Does this mean I'm good to go and all is at max?

Thing is, my cable says "High Speed" not "Ultra High Speed" but if it wouldn't be 2.1 I wouldn't be getting the second checkbox as green, right?
