A:AnswerDon't know but these Westinghouse TV's have a bad reputation. You probably should return. Ours kept freezing up, had to unplug to reset it. We returned ours.
A:AnswerYou can't browse or download. AND my tv died in less than 60 days. Westinghouse requires that I pay $100 to recycle and then will send me a REFURB!
A:AnswerI have a different westinghouse model, but all of the hdmi ports should be 4k, you will have to go through a setting on the tv to switch the hdmi port from 1.4 to 2.0.
