Ask a Question

Q: I’m so confused.  If I want a 40in wide TV how do I measure correctly?  I was told you measure diagonally.  So where my confusion is, is what size TV should I be looking for?  What should the measurement be diagonally. Advise please.

Purchased last month. Upgraded from a 1080p to a 4K. A very wise decision. had apprehension about the brand, since I went from a Sony to VIZIO, but you must think outside the "Sony circle" and so far I am not regretting it. Longevity has to be seen.

Using the tv daily I’ve noticed that with the cable remote control, I need to be especially careful about the timing as the lip sync has a tendency to be off a bit… so I’ll need to re-set everything again to get it corrected.

I have a few problems with it and thats the fact that it doesn't remember my wifi passwords for when one goes down, so there is no automatic connection. Which is kind of a bust being the television is supposed to be a smart tv. Another problem I've been having is the spund goes out periodically. Which isn't cool. Also in terms of spund quality its not very loud. So you will need some sort of sound system of you do purchase this "smart" television. The picture quality fantastic though. You really can't have any complaints on that aspect. If its movies/shows full brights or dark imagery from horror movies/shows, we haven't been dissatisfied. Also playing video games is great because there is no distortion or refresh rate issues what so ever. Would I recommend this particular television? ...Mmmm I'm honestly on the fense about that answer.
