Bought 2 of these for different rooms. One worked fine and although the picture is sharp, it isn't markedly better that my 2yo non-QLED, non-HDR 4K TV. The 2nd TV had "dark shadows at all 4 corners of the screen. Vizio support sent me a new replacement and it had the exact same problem PLUS one additional issue in that the screen never went completely dark, even when the TV was turned off. Spent an hour with Support with no solution. I am returning the replacement.

We replaced our 60" Visio Smart TV with the 70" Quantum M6 Series on 11 July 2022. The improvements are amazing. A person could spend all their time watching all the content available on the Home page. The picture is so big and pleasing to the eye. It feels like the people on the screen are actually in the room with us. Our viewing chairs are about 12-13 feet from the TV. I downloaded the operator's manual to my laptop. I am planning to read and learn how to get the most out of the TV. I look forward to many years of viewing pleasure.

[This review was collected as part of a promotion.] To sum it up in one word would be hard but “wow”! I have been buying TVs with Roku built in because I thought that was the best option, but boy I was wrong. Most of the time I got an OK tV with the Roku that I have been used to. Vizio's picture is awesome and the available apps are spot on. This will be the only brand that I purchase from now on. Thanks again.

Have had a Vizio in our main watching room for almost 20 years, which we recently replace. We made the mistake of going with a competitor's SMART television and had a HORRIBLE experience with set-up--could never get our home audio system to "talk" with the TV. After two full days of trying, we realized we should have stayed with Vizio. In 15 minutes going through the remote control prompts EVERYTHING works! Can't be more pleased! Our excellent picture is back, and the set up was no sweat.

I bought this TV on a whim because of my existing set was going out. As usual with Vizio the picture quality and features are hard to beat for the price. The 70 inch screen was a perfect option for us. 65 would have worked but 75 was to big for our situation. My only personal gripe is as usual the sound quality is lacking. I would have given this TV 6 stars if I could if the sound was on par with everything else. Could easily be fixed with a sound bar or surround sound. Thank you Vizio for such a great option of an entry-level TV. Its seems to be above par for that title.

Have another Visio and have been pleased with it. When I wanted an upgrade from my 48 inch, I found this one. I also cut the cable at the same time and am happy with the built in apps and the many possibilities for downloaded apps. It is not quite as sharp as I anticipated for a 4K, but there is not much 4K content available. Overall, 8 highly recommend.

[This review was collected as part of a promotion.] We purchased our 75" VIZIO earlier this week. So, early on we are very pleased with it. I did a lot of research on TVs and considered other manufacturers like TCL, Samsung, & LG. We chose VIZIO because of all the features we got for a great price. The VIZIO and our model reviews were very positive.

[This review was collected as part of a promotion.] Bought this for the outdoor room to watch football games. Picture is clean and crisp. Easy set up and registration process. Excellent variety of apps to chose from. Perfect for streaming or watching live TV. Would recommend this model.

[This review was collected as part of a promotion.] I bought my first VIZIO tv in 2009 and it is still working beautifully. Since then, I have bought a VIZIO for our guest room and now the M-Series Quantum 50-inch 4K HDR smart tv. The picture is amazing and the hues are perfect. The Dolby sound is wonderful and the smart audio stops the loud commercials. I will buy any other brand of tv.

[This review was collected as part of a promotion.] I just received my new tv and am very excited. I purchased the M series and glad I did. The picture is crazy good. Set up was so easy. Like the format of the apps. I have purchased several Visio's in the past and won't buy any other brand!
