Question: What is the difference between M3D550KD and M3D550KDE? How come new version KDE is less price did they change anything internally?
Document: Anything less than perfect HD looks bad on this TV. I suppose most folks will not care too much about this, but I still watch some old shows and movies that are not in HD, and they are almost unwatchable. Of course, I know it won't look as good as HD, but this is just ridiculously bad. I do compare the picture quality of this TV with that of my Samsung LN46A950... a TV with the most perfect picture I have ever seen, SD or HD.
The Vizio M3D550KD is an excellent buy and this review will explain to you why. If you are looking for a new TV set for size, 3D, or value make no mistake this is the one for you. The best thing is you do not have to sacrifice quality as well.
What an awesome tv for the price! We love it! Was looking around quite a long time for a great tv to come along, and this appears to be it!
I did, however, notice that the box it had come in had a lot of various address stickers on it, including SAM'S CLUB. I called Amazon CS on the 28th after it showed up to inquire why that was; was this a returned/refurbished unit? The answer was no, it was most definitely a brand new unit.
The vibration is intense and not all the time, at certain frequencies the sound is so bad as to be completely inaudible. I contacted Amazon again and was encouraged to go through the Vizio warranty service. I had already registered the unit with Vizio, so I did contact them. They set up an appt for someone to come out and repair the unit with a new part for May 2nd.
I had purchased on Amazon, with Amazon prime shipping, and it was a brand new unit with their name on it! However, they were adamant, they were not going to do anything about it because Sam's Club should've returned any unsold units to them, rather than selling them at a discount to someone else who could then resell them.
Their guarantee lasts for 14 days. We received our HDTV ten days after our Amazon purchase and the HDTV worked for several weeks. We paid to get the HDTV repaired and and have no warranty for a new product. My final recommendation is to not to buy anything from GPCK INC., Vizio or Amazon. None of these companies support the products they sell as new.
I purchased this through amazon warehouse deals in &#34;like new&#34; condition. It appeared that the TV had never been opened before upon receipt. With this said, the TV would go black (like you cant see anything) after about 1.5 hours of viewing. It also had an annoying flicker at the very top of the screen when showing programming in 4:3 format (non hd).
For the price, about $1,000 less than a comparable Samsung or LG, this set is a real bargain.Just a few things for anyone considering the Vizio. 3D is very good. Have tried several 3D discs like Avatar and the experience is impressive. The four HDMI plugs are more than necessary, but they may be welcome to folks who route many different things through their TVs. Remote is slow, and the slide out keyboard nice, but made for small hands.
In the stores and online, I compared reviews, editor rating, specs, passive versus active 3D  and in store image quality. It came down to 3 passive 3D LED TVs: the Visio, a Panasonic and an LG. I was leaning towards the Visio because of the reviews, specs, price ($1000 - $200 - $500 less than the other 2) and Costco's 2 year warranty. I then took my wife to the stores to compare the TVs.
