Question: Does this TV have a built-in HD Tuner?
Document: Considering this model TV cost under the average of two month's car payments I will get years of satisfaction from this TV. Useable Apps, NAS streaming support, built-in WiFi (HUGE unexpected bonus) and extending my livingroom TV viewing experience even further with crisp full HD picture that looks fantastic once you've tweaked some of the picture settings.I did not expect a budget minded upgrade to be so appreaciated. Vizio has earned a contenders position in the TV game after what they've been releasing product wise.
I love this TV. Setup was super easy, and the apps run very easily as well. I mostly watch HD local channels with an HD Antenna, and Netflix.
Love the options and quality. I moved another Vizio upstairs and use this for my main TV viewing. Love the quality and the built in Apps. For the money, you can't beat it. The delivery also included set up, confirmation that it was working, and removal of the boxes. WOW!
It's big...very big. 4 feet across. The picture is beautiful. Movies are crystal clear. Gaming is awesome. HD TV is fantastic. It was very easy to hang on the wall. Not very heavy. Lots of inputs to use. Internet ready with WIFI. When Netflix played on TV the sound is played back through HDMI cable to my sound system. Great option.But it!
I often resorted to my Playstation or ChromeCast instead.I did not realize the &#34;E&#34; series was meant for economy. I thought I had done my due diligence reading reviews but apparently those owners were not nearly as picky as me, or they were just blind. I suspect in reality, they upgraded from either a smaller set, or a non HD TV and did not notice the problems over impressively large display.
Wish I could give more info but it seems to suit with fine with Directv HD. I LOVE THE YOUTUBE app! I use that all the time and it works so well on this TV (see question regarding that below)I do have a QUESTION for anyone who reads this review. The 47 inch razor and this E550i-A0 are both smart TV's with the same apps. The Razor TV's Youtube App isn't nearly as responsive as this app.
I didn't want all the bells and whistles. I only wanted two things in the TV and I got them.This is a 55" high-definition (1080p)LED TV with built-in Amazon Prime and Netflix streaming. There are a couple other features  available (hulu, vudu(?)) that I haven't gotten to, but I don't use them yet.Set up was trivial, Picture is great. Price under $700, delivered. Perfect!
Now that I have my cable and XBox hooked up to the TV as well, that setup no longer worked. So I hooked my RCA cables (Red and White) from the subwoofer (Built in amp) to the tv to make all audio run through the speakers. Then I had to turn off the TV speakers. So far so good. Then I changed the tv from fixed volume input to variable, so that I could control the volume with the TV remote instead of the speaker knobs themselves.
This is a Great tv, even though it arrive late from the carrier it arrived in a perfect Package, not like the 50&#34; seiki. This is a deal awesome tv, I have always bought vizio tv's and never had a problem with them they are great and well built. What can i say good buy
So unless you are a TV buff, you shouldn't really notice any issues.
Answer: yes
