I purchased this TV about 8 months ago from costco for $750. I was absolutely surprised to learn this had so many features for such a low price, especially never really hearing anything about the company Vizio. To say the least I have been very happy with my TV. The picture is really quite impressive, with detailed and balanced colors...not overpowering like some over-saturated plasmas. The black level is probably the only part that could be improved. I recommend turning off skin tone, and some of the wacky picture enhancing features, and using a color calibration feature on a dvd. (finding nemo and most pixar movies have these buried in their extras menu) I can run my blu-ray and xbox360 at 1080i, along with HD broadcast cable. Now some people will complain about the tv not having 1080p, which in all honestly is a huge gimmick. No broadcast is ever televised in 1080p because of bandwidth constrictions, so making sure you have that for 'the big game' is a COMPLETE waste of your time. Most people cant even tell the difference between the two are unless they are side by side and playing a movie with super fast motion. 1080 resolution for under 800 bucks? You've come to the right place! As far as the sound goes, its pretty average (very mid-ranged)... better than a tv you might pick up for 200-300 bucks, but certainly not home theater quality, but really what did you expect? No high priced TV really sounds that great either... The only people that complain are the same people that end up hooking it up to a surround sound system anyways. The average user should be quite satisfied. I do recommend turning off the 'surround sound' feature, as it picks certain sound frequencies and channels and tries to play with the volume to give the illusion of a wider sound. Really annoying. This is a great purchase for a person who values a dollar. My mother and all her friends have this TV in their houses because of our recommendation. Absolutely nothing less than 5 stars.
Customer Review: Bought for the bedroom
I did a lot of research, both on the web and going to the stores to compare the LCD tvs. I wanted to replace the big and bulky tv that was there. After reading the reviews and doing my research I purchased this at Circuit City because they price matched + 10% so I got a really good deal! I had read about the audio problems and would say this is true to some degree but I wasn't wanting it so much for sound. I figured I could always hook up a surround sound system if I wanted that. The picture quality is just as good, if not better, than the expensive models. Also, I found that when it was hooked up to just cable and no box then I got more channels than I was subscribing to. I got a box because I wanted the HD and I wanted to know the channel number. I bought a swivel wall mount from Sam's for $57 and was able to find someone on Amazon that sold just one component shelf so my tv, cable box and dvd are hung very nicely and I don't need any extra furniture in the bedroom--freed up space by wall mounting! All in all the whole set up of wall mounting the tv and the component shelf, and hooking every thing up took less than an hour to do. I think Vizio is putting a lot of pressure on the other maker's and that's why I have their prices come down a little. I don't care, I will still stick with the Vizio just for that reason. Quality and the right price!
Prior to the Internet revolution, buildings usually had two wiring systems, the electrical service and the phone service. When computer networks were required, phone lines were the only means available for data transmission. The original networks that were created for computers to share data simply piggybacked over existing connections and technology.
Today, more options are available (and needed) to meet the networking needs of consumers. A good rule when projecting the future of communications: whatever you can imagine for the future, and multiply that by ten. Who twenty years ago could have predicted the Internet or HDTV or cell phones or IPODs. And given that technology growth in communications has proven to be exponential in the past, we need to multiply that experience by a factor of ten for the next twenty years.
When dealing with the design and construction of a new facility, it is important to identify needs early in the process. When renovating an existing facility, many of the same considerations should be addressed, and the task is often more challenging.
Structured Wire
Structured wire is a technology of electrical interconnect, and is rapidly becoming standard in many parts of the U.S. The products try to anticipate future needs, and provide standardized methods for implementation. A Structured Wire facility includes telephone, computer networking, video, and sometimes fiber optic facilities. Structured Wiring Service Panels are usually about 4' high by 4' wide and are installed in a service area such as a garage, attic, or basement. The Structured Wiring is most often installed in new construction, but it can be utilized in existing structures.
The Structured Wiring Service Panels for a structured wire installation is a central panel where services (cable TV, telephone, satellite, internet, etc.) enter the house. A minimum requirement for each panel is a telephone-connecting block for terminating the twisted pair, and a passive cable splitter for the coax. Room should be left in the panel for upgrades.
Although individual Ethernet and video cables can be used, specifically designed multimedia cables are becoming standard. A dual cable, for example, consists of one Ethernet and one video interconnect under a single jacket. Another composite construction could include 2 Ethernet cables for voice and data and 2 video cables. These multimedia cables speed the installation time because multiple cables can be pulled at the same time, and it minimizes termination times since all ends are identifiable.
Ideally, the wired network has a "home run" configuration: a separate interconnect for cable TV, phone, and Internet data transmission is made from the Structured Wiring Service Panel to every point of use.
Structured Wiring panels are used to provide the miles of cable interconnects required to distribute Audio, television, security camera video, telephone, and digital communication applications, and now combines it with multimedia facilities. Structured wiring works well with a wireless network because administrators can connect wireless access points throughout the house through an Ethernet connection.
Computer Networks
The right technology choice is driven by what kind of property is being serviced. In a good communications interconnect plan, all interconnects are run to a central location. It may be OK to run a phone line in series (room to room), but it is not OK for Internet network cables.
Technology changes fast.
- It was only twenty-five years ago that Steven Jobs said that no computer would ever need more than 64K of memory.
It is important to future-proof your plans. Fiber-optic solutions seem to be an unnecessary luxury today, especially with the performance available with high speed Ethernet. However, the majority of technology solutions for residential and small business applications are currently based on Ethernet.
Wireless networking (WiFi) is another technology that is rapidly impacting computer networking. Market research firm IDC projects that the total number of enterprise WiFi access points installed will grow from 1.6 million units in 2006 to 11.5 million units by 2010. Up to 20 users can connect to a single WLAN access point and receive adequate service. IDC also predicts that Ethernet switch ports, those predominantly deployed in enterprises, will grow from 172 million units to 208 million units in the same period.
Ethernet
Ethernet is the dominant standard for hardwire data networking. Ethernet hardware is usually standard in all new computers. If the method for high-speed data (cable modem, DSL, etc.) is hardwire, then the interface to the computer will usually be an Ethernet port.
Ethernet interconnections should not exceed 100 meters, and separate cables are needed for data and phone. It is possible to run Ethernet in the same jacket as phone, but it can be unreliable, and is definitely not advisable for High Speed Ethernet (> 100 Mbps). Use a separate cable, the "home-run" design, where possible from the network switch to each point of use.
With new construction, it is also advisable to interconnect buildings with conduit. Install it in the ground while it's still cheap to do so, and, keep the ownership rights. This will future-proof the property for later upgrades.
Retrofit Strategies
There are two common methods for retrofitting buildings: Wireless and Ethernet. Wireless has the apparent advantage of being less expensive and easier to implement, especially for retrofits. However, this is not always the case. Today, the answer is probably a combination of both systems. At points of use that are obvious and static, for example the home office, an Ethernet connection is appropriate. Overlaying this system with a wireless (WiFi) network provides improved flexibility.
Wireless
Wireless Ethernet (802.11) can be a good choice for communication retrofits for small projects. WiFi operates on radio frequencies (RF) and was developed for wireless digital communication between personal computers and consumer electronic devices. Most new computers include built-in WiFi support. Wireless Ethernet has applications including large buildings. Wireless access within common areas of a property, such as a pool area, can be an elegant solution. Wireless also is an excellent choice where it is difficult to run additional wire.
Hardwire
In some situations, rewiring can make more sense. For larger projects, a hard wire approach is more reliable, and in the end, cheaper. Wireless looks good "on paper", but in a large building, universal connectivity is difficult. The average cost to rewire with Ethernet cable is about $300 per point of use in large buildings. Having infrastructure in place for future expansion may justify the expense of rewiring.
Environmental issues must be considered when rewiring. Issues such as asbestos and lead-paint abatement are examples. There are those applications where rewiring is not an option because of construction constraints, unless exterior conduit is used, and esthetics often preclude this option. Once the wiring is installed, implementing the network is straightforward using standard Ethernet hub or switch equipment. Remember that there is a 100 meter distance limitation with Ethernet. In large projects, locating Ethernet switches in each building or on each floor of a high rise resolves the issue.
Fiber Optic vs. Ethernet
Fiber is probably not the solution to deploy today given Ethernet's ability to handle high speed communication over the short distances typical of large buildings. But it is difficult to anticipate the future. Fiber optic cables are used instead of traditional copper cables because this technique offers more capacity and is less susceptible to electrical interference. Fiber optic is becoming more common as a way to provide very high speed Internet service (100 Mbps and higher).
Uncompressed HDTV
If you want to distribute uncompressed video, say from the output of a satellite or cable receiver, then the bandwidth requirements are significant. The alternative would be to distribute the compressed signal, and install a receiver (with decompression) at each point of use. If you are in the first camp, read on, otherwise you can skip forward to the next section.
Today's video installations grow ever more complex, with source components positioned a good distance away from the display. The distance is the biggest factor in determining which technology to use. There are two choices, Copper or Fiber Optic.
An uncompressed digital video signal is a challenge. Fiber optic interconnect is the best technique for DVI and HDMI, because of the enormous bandwidth available. The bandwidth of Ethernet is less than 0.6 Gbps, and this is much lower than uncompressed video data (1.65 Gbps), it is easy to understand why fiber optic is better when it comes to high bandwidth digital signal transfer for long cable runs. Typically, 1080p signal would mean 1920 x 1080 pixels at 60 Hz. At this high rate of speed and large bandwidth of data, the impedance of many copper cables can cause signal loss at less than 20 feet, and this results in significant distortion.
Interconnect reliability over time should also be considered. The optical conversion electronics should last at least 80,000 hrs of continuous operation. Fiber optic cables are immune to electrical interference such as gadio frequency interference (RFI). With Fiber Optic Conversion technology, there is zero impedance (zero loss during transmission).
Summary
High quality interconnect is an investment. As digital video technology improves, you may be upgrading your DVD player or TV and it is important to make sure your interconnects do not become obsolete. Utilize a technology good to at least 1080p. Fiber Optics may be more expensive, but the price differential may be worth consideration for future-proofing your system now.
The goal is to deliver a cost-effective, future-proof deployment. It is more expensive and difficult to retrofit later. Inexpensive computing, the Internet, and digital communications are transforming the our planet. Twenty years of stunningly rapid advances in technology have brought computing into businesses and homes in ways that were recently not imagined.
