I have a Vizio. I've had it for a little over 2 years now. The picture and everything is great. There are a couple of problems with it, however, that have greatly annoyed me.
1) The sound is never right. If I put on the auto audio adjusting it makes it impossible to watch a movie because it auto adjusts too far down for dialogue, and then becomes absolutely blaring for the loud scenes because you've turned it up so much for the dialogue scenes. I've tweaked settings, messed with it over and over, and have never been able to get it to avoid this issue. If you set it to off then you wind up turning the volume up and down constantly as well depending on the type of scene.
2) It has 5 HDMI ports. Which was wonderful when I first got it because I could have my SAT on one, my PS4 on another and my Xbox One on yet another one and just changed between inputs. So sweet.
The problem? 2 years later and I'm down to 1 HDMI port (all the others have completely gone out) and the one I do have that works goes out (Black screen) for a few moments at least 1 time every time I turn my PS4, Xbox, or SAT on.
I'd look into spending slightly more and getting a better brand, that's just me. When I finally replace it I will be looking for a much better, more reliable, brand.
