A:AnswerI have had zero issues with streaming with this TV but I have quite high speed internet somewhere in the 1.2 gb per second range and I use wifi 6 and a fancy router that is always making sure the router is broadcasting to the least crowded channels ..not sure if this TV has an Ethernet port but maybe if it does.go with that and you will get a more stable connection ..you can always adjust the quality of the stream down to make your internet not have to work so hard keeping up ..you can always try a streaming box like fire tv Roku or Nvidia (which I highly recommend) they are much more.capable for handling streaming in 4k
A:AnswerNo this service was just announced and the TV's just being released now that are high end have this ...most budget models from late last quarter and this year are not gonna have thise options ..there is a list of TV's that have it if you Google it but most are in the high end ranges if the big 3 Samsung Sony and LG
