A:Answer Hi Dave, Thank you for inquiring about the TU8300. 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. This series has 2 HDMI ports, each capable of Auto Low Latency Mode (Auto Game Mode). The “HDMI In 2” port additionally supports eARC.
If you are looking for a TV that can further support 4K@120fps, please check out the first series in our 2020 TV lineup to do so -- the 55" Q70T with 4K@120fps available on HDMI 4. All Samsung 2020 model year QLED TVs 55” and bigger starting from the Q70T Series have 4K@120fps, VRR and FreeSync. If you have further questions, please reach out to us at 1-800-SAMSUNG. Thanks, ^Scott
