I fall under the Hallmark/Lifetime watching category so I'm looking for some advice. My husband and sons have been researching TV's for the past couple months and have me talked into a new one. They are getting the new Xbox One X and feel that since it is 4K capable, they also need a 4K TV. After reading several articles and reviews on the 4K TV's, I'm wondering if they need one or if an Ultra HD would work just as well? My husband prefers the Vizio brand (we've have 3 and have never had any issues with them) and the boys want a 65"-70". I saw Sam's Club has a 70" Vizio XLED E-series on their November 11th sale but I can't quite tell if that is a good model or not. One review said it was not good for gaming, but then another one said it worked great. I looked online and can't quite tell the difference between the P, M and E-series (other than price). Any help you can give me is greatly appreciated!
