Sound too low

Sound is too low. I have to keep adjusting the sound. Just when I think I have it right my son ask “Why is the tv so loud?” I turn it down only to turn it back up. There’s nothing wrong with my ears.

Software issue out of box?

I am hoping to change it later, but I am seemingly having a software issue where it will randomly kick me out of what I am watching and restart. Since the TV is brand new, this is very frustrating.

One of the most unreliable products I have ever purchased. Glitching, freezing, failure to connect to wi-fi, all (according to research) due to failures of the television software and hardware. Don’t waste your money.

Problematic sound

I use it as a computer monitor. You don't need to install the phone app for that, just exit the initial setup with the back arrow. My old Vizio remote works. The new remote has a ring on top that serves as an ok and navigation button - it's not marked OK so I thought it's just a decoration not a button. To get normal colors for a monitor, not "bubble gum", I set the sharpness to 0, color to 35, color temperature to normal, brightness to 26, black level and contrast to 50. Adjusting the sound was a bit more problematic. The bass is so enhanced that it gave me headache listening to it from 2 feet, so I set the bass to -5 and turned off all sound "enhancements" which distort the sound. Sometimes, when I wake up the TV, the sound output is reduced, so I have to turn it off and on again. It's not supposed to do that from the very beginning, so I worry it may not last 10 years as my old Vizio.

This was a gift for my Dad. This is the only brand he likes. This replaced an old Vizio tv. You won’t go wrong with this brand!

Horrible! Won’t stay connected to the internet, when our other tv, that’s further away from the modem works great!

When delivering a TV to someone home at least knock or ring the doorbell because the TV was stolen from in front of my home.

The Vizio 40” TV met and exceeded our expectations. The picture and colors are amazing. It has a very clear picture.

Good for this application.

Good value for what it is. Bought to operate on WiFi on a large boat. Was a little bit frustrating to set up but overall worth the purchase price.
