A:Answer Hi JohnDoe,
The DU8000 TV supports 60Hz and because HDMI 2.1 is a complicated spec, we hope that focusing on TV features will be more helpful to you when deciding on the best model for your usage scenario. The DU8000 TV has 3 HDMI ports, all of which support Auto Low Latency Mode (ALLM) and Dynamic Metadata (HDR10+). “HDMI In 3” port further supports eARC.
