A Great Buy for a GREAT TV Review by Sandy

Just purchased the Vizio M401i-A3 a few days ago and it not only met my expectations but surpassed them. This is my second Vizio in 3 years and could not be more pleased.
The picture is as clear as day and produces quality sound.
A great tv!

Blown Away Review by Lil Fin

I am a person who buys the best after researching for weeks about something, I was really looking toward a SamSung Smart TV but this M Series caught my eye, so I compared them the Samsung was $25 more so not a huge price difference. I went to the local Sams Club for food, and seen this sitting there on display. It was only $398 for this M401i-A3 I figured why not its a lot cheaper than what I originally seen it and than the Samsung. I am absolutely amazed at this TV, the picture is perfect. I also have a 47" top of the line LG and the picture on my Vizio blows the LG away I couldn't believe it. The Smart TV functions work better than expected too.

M401i-A3 Excellence! Review by JimBob

The M401i-A3 is my latest acquisition and Vizio has succeeded in designing and producing the ultimate 40" TV. The picture quality is the essence of excellence! With easy to follow set up instructions, now included for viewing right on the screen, I calibrated the picture to meet my specs. I love the way the menu selections are easy to use with clear instructions to follow. This TV is beautifully built and has a real quality feel from the base to the thin bezel and the viewing picture. The sound is right up there with the best in this class of televisions. I subscribe to NetFlix and I am very impressed with the ease of access and performance this Smart TV provides for this venue.

Thank you Vizio employees for making this TV! Cheers!!

I appreciate a great tv at a great price Review by Mr. Z

I have had my 55" E-series TV in the living room with a Vizio 2.1 surround sound (great sound) for 2 years now. It is fantastic indeed, but when I got my 40" M-Series for the bedroom, I was like, whoa. I want to thank you all at Vizio for making some really great TV's.

jk;aker (Just so you all know, a real customer wrote this and not some paid marketer). ;-D

P.S. Vizio has not disappointed me so far. Keep up the great job to all you engineers and assemblers!


One Happy Customer...

If you game ... this is your tv Review by huscles

I needed a new 1080p gaming hdtv ... I've been using a 24" vizio 1080p because bigger screens always added input lag and response times ... but not any more ... this tv has 26 ms of input lag and 5-6 ms response time ... this is good ... now i cant lie its a slight difference between my 24" and this 40" but not enuff to make my shot off or do any moves in nba 2k14 ... also on battlefield 4 targets are not a problem ... with some tweaking of the contrast and brightness along with other settings i have a picture that looks great ... over all this is a nice gaming tv

Great TV! Review by GHARV

When shopping for a 40" Smart TV, I was looking for the least expensive model.
Hands down--it was the Vizio.Then I got some surprises.The picture quality is outstanding, and its SMART TV function easily surpasses that of a more expensive brand that I purchased only three months before.

I was also impressed with its stand alone audio quality. Sure, a soundbar or added speaker system would increase audio quality, but this set is in a bedroom, and the sound is more than satisfactory. The bedroom has a large picture window, but I experience little if any glare on the screen.

You definitely get more for your money when you buy a Vizio TV.

Within the next few months, I plan to purchase a third SMART TV, one with a larger screen for the living room. There's only one brand I'll consider--Vizio.
