AVR Connections to OLED TV (1 Viewer)

[johnnyR104]

Recently got a 65" LG OLED evo C-4 TV and just got a Denon AVR-X`1700H. I will be connecting the TV to the AVR using a 48GB Ultra High Speed HDMI cable between the eARC ports on both. I will also be connecting my Apple TV and a Blu-Ray player directly to the AVR on either the 4K or the 8K HDMI ports.
I am trying to get the best resolution so do I use the 4K ports or the 8K ports for these HDMI connections?

Thanks in advance to all responders for your time and attention.

The TV is 4K, so it really doesn't matter. Your TV can't take advantage of the 8K connections, and there's virtually nothing that even provides 8K, outside of high-end gaming stuff, I suppose. That's why you don't even need the 48Gb cables, but they won't be a negative
