- Most Excellent Review by Mike
-
I purchased this television a little over a week ago. I am totally satisfied with it. I will recommend this television to anyone who asks. Excellent picture, Excellent sound, Very good selection of television modifications to enhance picture etc.

I am very happy I bought this Vizio.(Posted on 11/13/09)
- EXCELLENTTT!!! Highly recommended! Review by RJ2544

I now have 2 Vizios. 26" for the breakfast nook and this 42" 240 HZ in the family room. The other reviewers have already said it. It's a great tv. I paid $915 tax and delivered from Sam's Club. Of course, you can find cheaper 42 inchers, but this one is most excellent. Happy viewing!

- Costco and Vizio - Perfect Together Review by BigMatt
-
My family has enjoyed our Vizio LCD HDTV for years, and it's never let us down, so when it came time for me to pick up a HDTV for my parents, Vizio was the obvious way to go.
Although we had no reason to believe that the unit would be anything but completely reliable, purchasing through Costco - which extends the warranty to two years - provided us with additional peace of mind (and a great price). Vizio certainly selected a spectacular retail partner in Costco.
Thanks to Vizio's innovative packaging and clear labeling, it took about two minutes to have the TV up and running. Once the cable box became active, we were treated to a stunning picture and clear (if not exceptionally loud) sound. With some of the high-definition nature channels, it's as if you're looking out a window. The beautiful, backlit remote is straightforward and comprehensive.
Watching sporting events on this TV is treat - there is absolutely no blurring or "trails" no matter how fast the action gets. DVD playback is spectacular; I can't wait to see the picture from Vizio's Blu-Ray player when I get it for my parent this holiday season.
In sum, this is an excellent HDTV for a compelling price, sold by a manufacturer/retailer pairing that stands behind the product. You need look no further than this Vizio at your local Costco.

- Whatta Great TV Review by HandsomeBill
-
Had this TV up and running in 5 minutes. Idiot proof. Beautiful picture, decent sound. The price is right for a set of this quality, you can't go wrong. I love the smooth scrolling picture though it takes getting used too. Remote is easy to use and operates all necessary functions well. I hope it lasts for a long time. Probably the best picture I've seen on a 42" and I have been looking around for a while. I highly recommend it :)

- All the bells and whistles with a Breathtaking Picture Review by Mike
-
My first review I've ever written but have to tell everyone about this very up to date HDTV the VIZIO SV471XVT 240HZ 47" HDTV.
I know this is a little lengthy but my brand new VIZIO SV421XVT HDTV for our living room and this set is absolutle awesome.
Has all the bells and whistles.
I mean right out of the box. Set up to my DVR Comcast cable box and was easy. Standard picture was nice but when I switched over to a HD channel my jaw dropped. Snow covered mountains and wildlife. The HD picture was breathtaking.
I started patting myself on the back when my wife expressed a very pleased kiss on the cheek saying. "OMG the picture is beautiful and so sharp and clear WOW good job honey"
I got mine Monday evening. I set the picture mode on VIVID and Monday Night Football was crystal clear and the uniform colors really popped switched over to watch HBOHD movie for a minute picture still set on VIVID (one of many viewing modes) and in this particular movie shot of the front steps of a courthouse leading to the street, the picture was so clear, clean and smooth I can only compare it to my wife's Soap Opera shows. The picture had that the of appearance was 3D like. Very smooth. Got right up to it and saw no lines what so ever. Almost looked LIVE but it was a movie. The staged Hollywood shots of a residential neighborhood the manicured front lawns and landscape of the peoples homes were so vivid you could tell that the plants and flowers were fake they looked plastic. A little to VIVID maybe. That’s what I’m talking about.
My 55" Mits rear projection HDTV downstairs in my family room that I bought about 7 years ago was top of the line then. The Mit’s TV was calibrated and looks good but the picture on the 240HZ Vizio SV421XVT HDTV is in a class of its own. Just spectacular and the remote runs everything and is easy to program.
Yesterday I came into work with a mission to find the formula to calibrate my Vizio just out of curiosity if maybe I could make the picture even better. So I started googling for calibrations and found about 4 calibration formulas done from calibration disks by people with the SV471XVT and only found 1 for my SV421XVT".
Assuming the similarities I printed the pages out for both and took them home. When I did the calibration for my 42” HDTV the changes in the setting were so minimal compared calibrations to the original.
For example: BACKLIGHT originally out of the box was set at 100 calibration setting off internet was 98. Any of the other calibrations were like 1 or 2 clicks - or + difference.
So in my opinion the default settings in picture setting are SPOT ON right out of the box so your sets settings should be also. The calibration changes I got off the internet were barely even noticeable after I entered them and looked at the picture. I reset the picture back to its original default settings. Perfect
It's your personal viewing preference of how you like your movies, sports, and broadcasts to look. I'm happy with the VIVID Picture MODE on 24/7.
From what you say about the money you want to spend the SV471XVT is around 11 to 1200 and I’ve seen it cheaper.
This set is ready for the future. Mine has 3-4HDMI inputs. Can input Computer, MP3 and Photo and Video Camera.
I have it hooked up to a brand new Vizio Sound bar that I bought off of E-Bay for $156 so your have the extra money to pick one up if you like. They run about $350 regularly. The 47" SV471XVT has a clock and a built in equalizer. The only difference I read between the two sets.
As you can tell I'm very happy with my new Vizio. I think you would be also. Just my 2 cents. Happy Hunting. Mike

MOVIES ARE JUST GREAT, EASY TO SET UP, I PURCHASED THIS AT SAM'S CLUB , IF YOU DONT HAVE ONE PLEASE DO YOURSELF A FAVOR GO GET ONE, YOU WILL NOT REGRET IT. THE PRICE WAS $848.00, I LOOKED AT LG, SAMSUNG, SONY. THE VIZIO COMES IN FIRST BOTH IN PRICE & QUALITY.

- Best Quality & Value Review by Little Mike
-
Purchase my VIZIO SV421XVT at Sam’s Club for $848.00. Tammy the Sam’s Associate told me about the Plus memebership and getting another year of warranty for free. Plus this additional warranty is added on after the factory warranty runs out.. So now I have two full years of warranty. Sports look great on this LCD TV. Football and Golf are crstal clear and no blurred motion (240Hz). The installation instructions are well written and the set up was a snap. I switch between TW cable and RCA digital anntenna for channels selection. This remote makes that simple. Overall at this time I would give the set 9.75 out of 10. Time will tell if this VIZIO LCD TV set lasts and if the design/manufacturing qaulity is sound. But if you are shopping for quality at a reasonable price this is the VIZIO LCD TV for you.

- Great tv for the money Review by Tucker10
-
Picked this tv up at costco for $899. I did quite a bit of research and this tv just couldn't be beat for quality at this price point. The pictue in both HD and standard def is much better than anticipated. DVD's look phenomenal. The sound quality is ok, but at $899 I'm not complaining. Overall, this tv gets an 8.5 out of 10. If you're looking for a quality LCD under a grand then look no further.
