New 70 inch TV

[This review was collected as part of a promotion.] I bought a new 70-inch Vizio TV, and it is by far the best TV I have ever purchased. From the vivid color range to the accessibility, this TV brand is superior to all others. I also do a ton of gaming, and the fast response time and HDR are perfect. I highly recommend Vizio since their TVs are more than just something to look at and watch; it's an experience the moment you turn it on.

So pleased with our new Visio 70” TV!

[This review was collected as part of a promotion.] We decided to upgrade the size of our master bedroom TV from a 52” to a 70”. We initially bought another major brand but were very disappointed that it didn't come with an optical cable. This was really important to us because we have a hardwired surround system and the other brand wouldn't connect to our receiver. We already had another Visio in another room that we were happy with so I was pleased to find that the 70” QLED had the connections and everything we needed. The connections were simple to our sound system and the picture is even better than the other brand we tried. We couldn't be more pleased with our purchase.

Better than expected, excellent value for the $

[This review was collected as part of a promotion.] After a lightning strike, our current tv and soundbar were toast. I wanted something larger than the 65 inch we had, but found that a 75 inch was too big to fit the space, enter the Vizio 70 inch Quantum. With reviews all over the place, I wasn't sure what to expect but have been surprised by the good picture quality from this tv. Decent brightness and clarity and the color punch from the quantum dot is very noticeable compared to the LG standard LED it replaced. My only real gripes are a brighter band of light around the outside edge of the screen that is noticeable in certain conditions but not all the time… also the speakers aren't very good but that was easily rectified with a Vizio soundbar that conveniently mounts to the underside of the tv with the included screw in adapters! Overall very pleased with my purchase!

Vizio 70 inch TV - affordable luxury

[This review was collected as part of a promotion.] For the price and among its competitors, this TV does an amazing job. We have had a 2.5k Bravia as well and the quality is very close. The calibrated mode takes some time to render dolby and 4k vision but when it does its worth it.

Excellent for the price range!

[This review was collected as part of a promotion.] Having owned this for about a week now, my only complaint about picture performance is that some of the lighting tends to be a bit too bright, even when changing the picture presets away from Bright towards Calibrated. Otherwise, the feet are a tad too big for my previous TV table but that's on me for not checking the dimensions before buying this.

There is a glare but so far that's the only thing I can say negative about this TV!
