I am pissed off if this is true . I spoke to a TCL rep on twitter and waiting on confirmation about the 65" VRR. It looks like only the 55" 2019 is getting VRR and not the 65" or the Q825. However all TVs for 2019 will get e/arc. This is BS if true. Why would they only have the 55" support VRR and not the 65"! Or even there flagship model the Q825. Wow.
