Models: Vizio XVT472SV vs. Sony KDL-46EX700
Description: 46" and 47" LED LCD TV
Resolution: 1920 X 1080
Power Consumption: 130W
We decided to do a side by side comparison review of these two intruiging offerings which can both be found for sale currently at Costco Wholesale Club. We reviewed the LED TVs with the same signal sources through the same inputs both post calibration. Our findings are mostly just fact but we've added some of our own thoughts and impressions as well. Both TVs are Spring 2010 models arriving now with similar feature sets including Hz rate upgrade to 120Hz or 240Hz, LED back lighting, and various other similarities. We highlight where the features and quality vary. Keep in mind what features are most important to you in using this guide to help you choose a TV manufacturer winner.
This brightly lit computer generated image from the Blu Ray version of The Fifth Element displays in rich detail on both TVs.
Test and Optimum Viewing Distance: 11 feet
Calibration: Both TVs calibrated relatively easy to D6500K. Turning the brightness or contrast up on the Vizio XVT will cause color shift. Gamma was nearly perfect right out of the box on the Sony EX.
Advantage: Sony 46EX700
Another scene from The Fifth Element the Vizio XVT472SV struggles to maintain post calibration brightness compared to the Sony.
Black Level/Contrast Ratio: Black levels both tested better in our contrast ratio testing and looked better with content on the Sony 46EX600. The Vizio's black levels were decent but can look a bit washed out with certain content.
Advantage Sony 46EX700
Note the dark shadow detail in Mark Walberg's shirt from both TVs in this scene from the Blu Ray version of The Departed. Shadow detail was a particular strength of the Sony and weakness of the Vizio.
Color rendition was close on both TVs. Here colors displayed a little more vibrant and with better contrast on the Sony 46EX700.
120Hz/240/480Hz Rate Feature Evaluation: Vizio calls their back light manipulated 240Hz rate feature Smooth Motion and claims that the manipulation creates the effect of 480Hz.. Sony calls their 120Hz rate feature MotionFlow and makes no such claims about the backlighting. Vizio's SmoothMotion works better when panning side to side (it is indeed smooth) and we must derive with fast motion as well. The problem is that with most content the feature eliminates natural intended background blur thus making it undesirable for most programming. Without the feature of course there is visible judder and jerky effect when panning side to side.
In the Sony 46EX700 the opposite holds true. MotionFlow feature does not introduce unwelcome effects and may be used with all programming, but it does not work as effectively at eliminating jerky effects with side to side panning and other annoyances.
Even
Inputs: The Sony 46EX700 has all inputs you would presently need or want. The Vizio XVT472SV lacks an Ethernet port for Internet.
Advantage Sony 46EX700
Aesthetic Considerations: Though the XVT472SV has a thinner bezel framing of just an inch which we like but is a hefty 4.5" deep. The table top stand does not swivel. The Sony 46EX700 is just over 2" in depth and comes with a swivel table top stand. The only drawback being a slightly wider bezel.
Advantage Sony 46EX700 (just barely)
Remote Control/Menu Funtionality: Neither remote control is backlit. The Vizio remote's top control buttons are too small, the Sony's very large but the remote is plain basic looking.
Even
Audio Output: Sound volume output from Vizio XVT's 15W X 15W speakers was impressive as was the virtual surround effects and definition. The Sony's 10W X 10W inbuilt speakers were weak in volume and surround sound quality with a hollow sound.'
Advantage Vizio XVT472SV
Internet Options: The XVT472SV does not contain Internet options. Sony wins this contest with a fight.
Advantage Sony 46EX700
Price: At $1299 for the Vizio XVT472SV and $1549 for the Sony 46EX700 we'll give this one to Vizio.
