I am a little confused: Here in the data sheet it says refresh rate of 120Hz, but Sony specifies 100Hz. There is no information here about HDMI connections, and in the comparison list it says "no" for HDMI 2.1. Sony says "FUNCTIONS ACCORDING TO HDMI SPECIFICATION 2.1: eARC". ...what is it really like: 120Hz or 100Hz / HDMI 2.1 or 2.0? Many thanks for your clarifications...;)
