There will be two ports supporting HDMI 2.1 at full bandwidth (48 Gbps) with support for 2160p120, dynamic HDR, ALLM, VRR. There will be a third port supporting HDMI 2.1 eARC only intended for connecting to your sound system.
Hello Al, All the HDMI ports on our 2021 lineup support HDMI 2.1. This TV does support 4k at 120Hz.
Even when it says it does support 2.1 I am having issues with the sites x .. it will not support the bandwidth can't do 4k 120 for me
Hdmi(1,2,4) are 2.1 audio & video. Hdmi input 3 is 2.1(audio only)(for outputting eArc or Arc).
HDMI 2-3 are full bandwidth, but are currently having issues.
Only HDMI inputs are full bandwidth 2.1 4K/120, but currently the Vizio is having issues with next gen consoles and a fix is being worked on. Sony hasn’t implemented VRR support into the PS5 yet, so that isn’t available either.
HDMI ports 2 and 3 support 4k@120, HDMI is eARC.
