A:Answer Hi MURPHY, Thanks for your inquiry. Unfortunately, the 750H doesn't come with HDMI 2.1 features. We recommend checking out the X900H. For X900H, the TV will support up to 48 Gbps transfer rate to support 4K120, Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and Enhanced Audio Return Channel (eARC) via a future firmware update. This will be supported on HDMI Input 3 and 4. Hope this helps! -Sam
