I bought this TV about 6 months ago. Have already had to exchange it once. TV is worse than windows with the extremely slow updates and we're are continually having to reset it to factory settings and stay all over again with app set ups. Should have purchased a Roku and not this "SMART" tv.

A few months after getting tv as a gift tv started randomly turning on. Check setting made adjustment but still does it randomly. About 4 months ago it started shutting off and coming back on. Check settings and all timers are off. I also randomly get a large line in right side that scrolls top to bottom.

2 old Year TV, i was having issues the 1st year, Vizio did something and it start working properly then same issues the second year and was told it is out of warranty so SOL Started a complaint they sent the repairman now no sound I have a 55 inch Samsung running for 11 years and never once had an issue with it Even the repairman said you wasted your money I opened the TV myself and did some repairs LOL Save yourself headaches and shop around

Bought this as a slight upgrade to my 2017 M55. Expected a little but more of an upgrade with the Quantum, but have to admit, there isn't too much of a difference in the picture quality. However, the few areas that are improved, are much improved. Had this TV about 3 weeks now. Not worth the upgrade as the M55-E0 was stellar already. If in the market for a TV and looking to upgrade this TV can't be beat for the price!

I have had Vizio tvs before with no issue. It was nice to have just a TV. Vizo should not be in the smart TV business. It works when it wants to turns on and off randomly. Unable to install apps. Not user friendly in the least. I really just wish I can by a standard on off TV.

I bought this tv a month ago and it looks great when it's not freezing or dropping the internet... The soft reset option seems to fix the problems, temporarily anyway... it this is how all “Smart” TVs behave, you are better off buying a dumb one and an Apple TV!

Have for 4 days and cannot print users manual. I cannot calibrate or set TV if something is wrong and I have to use other methods to read manual instead. Nothing better then having a printed hard copy in my hands. Instead of going to another device for the information. Please send me a printed copy or something I can print. Not a PDF. I cannot print PDFs

[This review was collected as part of a promotion.] You expect a state-of-the-art television to last longer than it's predecessor (My previous model lasted 10+ years) and you expect the company that produce it to stand behind a failed product. The fail began with three large discolored blotches and led to the TV randomly resetting, seemingly, every 60 minutes. If Vizio cannot recognize a moment in time to absorb a faulty product and acknowledge that, sometimes, you make a lemon, I will not continue to be a customer. My advice to anyone purchasing from Vizio - Caveat Emptor.

I bought this TV to replace a previous 4k model that did not support HDR. I am very pleased with this TV. I am seeing details I never knew were there before. And watching a 4k movie on my 4k Blu-ray player? Wow! Impressive! This may not be the top tier, but if it lasts like my last Vizio set did, I can look forward to many happy years.
