What kind did you get
I was looking to get a 70" HD... but now have been gravitating to a 4K.... still cannot pull the trigger since the cost is so high... I will have to be OK with the 48" Vizio.... that was a refurb...
I bought a 60" Vizio 4K. Its one of the cheaper ones and has a few less "smart TV" features but I dont care much about that. The specs may be slightly less than a Sony but to the naked human eye, the picture quality is the same on just about any of them.
In a few months you wont be able to buy anything but a 4K. Best Buy hardly has any regular HD models left now and I think when they are gone, they are gone for good. The picture on a 4K TV is amazing. However, its almost "too" realistic on some shows and movies. Sometimes it looks like the way a soap opera does. Like you are actually standing in the room with the actors which may sound cool but to me it almost looks fake. I like whatever filters they use in movies.
