Choosing the best HDTV is harder than you may think. Using reader feedback, along with having written, tested, and researched the subject since 1998, weve compiled a list of the most common buying mistakes when choosing an HDTV. By being aware of the pitfalls of HDTV buying, you can end up with a better experience, a better TV, and without the grief others have experienced.
1) Buying The Wrong Size Set
The most common eye-to-TV distance, called the Lechner Distance is 9 feet. Based on screen resolution, to see all the details in a Full HD picture (1080p) at 9 feet you need a 69-inch screen. As 32-inches is the largest selling screen size, clearly theres a disconnect here. Often people choose a TV thats too small due to budget, lack of knowledge, or the use of existing TV furniture designed for older 4:3 TVs (instead of the HDTV standard of 16:9).
The solutions: move up to a larger screen size, sit closer, or consider a less expensive 720p set. Being lower resolution, a 720p TV of the 46-inch screen size will allow you to see all the detail at the 9-foot viewing distance.
In other words, you can get a MUCH larger TV than you probably thing, presuming you can fit it/afford it.
2) Replacing Your Old 4:3 TV With A New TV From The Same Brand Name
So youve owned your CRT TV for 15 years, its given you great service, so you figure youll buy the same brand you know and love. You may be surprised to learn that brand is a name only, and not the same company (link). For example RCA TVs were once made in the USA by the RCA you knew. There is no RCA today; the company has changed hands a number of times and now the name is licensed to On Corp for RCA flat screen TV sales. Todays RCAs flat screens are made in China and require shipping the sets back to On Corp for warranty service (if the screen size is below 37″). TVs by Westinghouse, Philips and Polaroid are not made by the original companies either.
JVC is another brand of HDTV that are no longer made by the parent company. JVC, the creators of the VHS video tape format (remember that) decided to withdraw from TV manufacturing this year. Its sets are all now produced by contact manufacturer, Amtran out of Taiwan. Amtran also makes the HDTVs sold under the Vizio brand.
3) Picking an LED Because You Were Told It Has The Best Picture and Latest TV Technology
The most expensive TVs available today are called by their makers LED HDTVs. Weve heard salespeople tell customers this is a new TV display technology better than plasma and LCD. This is not true on several levels. First all LED TVs are really LCDs, merely with light emitting diode lighting (LED) instead of cold cathode fluorescent lamps (CCFL) used in regular LCD TVs. Except for energy efficiency, there are no inherent advantages to LED lights over CCFL (unless it includes local dimming backlight).
There are two types. One is called edge lighting, meaning the LEDs are located along the edge of the TV. They can be along the top and bottom, the left and right, or all four edges. Often TV manufacturers dont disclose the placement. Local dimming is the ability for the TV to dim some LEDs while keeping others fully lit. This provides the ability to get blacker blacks. The edge-lit designs found in most LED LCDs can only dim strips of the image .
To dim a specific section of the screen (such as one box in a grid of boxes) requires LEDs placed behind the screen. These are often called full array LED backlights. In 2011, the only companies currently offering this feature are Sharps New Elite 60 and 70-inch TVs (link) and the top of the line Sony HX929 series sets. LG will be introducing its local dimming LED backlit, FPR passive 3D, called Nano TVs, next month (link). All these TV represent the most expensive sets in the given companies product lines.
Edge lit LED LCDs often have brightness uniformity issues. Check out Geoffs article on the topic over at CNET. Edge lit LED LCDs (and CCFL LCDs) tend to have viewing angle issues as well, which well elaborate on next.
4) Thinking Viewing Angles Are The Same As Your Old Bulky CRT
CRTs (cathode ray tube) TVs have very consistent color, brightness and uniformity whether you view straight-on or from the side, above, or below. The same holds true for plasma TVs. LCDs and LED-LCDs tend to exhibit shifts in color and/or brightness and contrast as one moves off-center. This tendency varies depending on a number of factors based on the technology used to make the TV . If only one or two viewers will be watching the TV, and theyll be sitting near center (height-wise and side-wise) there wont be much difference.
However if you have a wide viewing area (like a big sofa), or you plan on mounting the TV above you (like over a fireplace), the picture quality with most LCD TVs is going to be significantly worse for those not sitting directly in front of it. One should consider this while looking at a potential TV, and consider plasma as an alternative.
5) Are the TVs Built-in Speakers Adequate?
As TV got thinner, the speakers got smaller and thinner as well. Most of todays flat panels, regardless of technology, use small downward firing speakers. This causes poor high frequency response and lower maximum volume. In a large room, or for viewers with high frequency hearing loss, there may be insufficient volume. The alternative is either external speaker system, a sound bar or a surround sound system (link)
6) Choosing 240 Hz TV
HDTVs using LCD panels at 60 Hz suffer from resolution loss called motion blur. If you watch fast action or sports, you may notice this phenomenon when a player is running down the field in the form of blurry legs (to name one such example). To improve motion resolution, LCD and LED LCD TV makers increased the frame rate from 60Hz to 120 Hz or 240 Hz (some advertise 480 Hz but they are really 240 Hz with a scanning (strobing) backlight.
This increase is done with a circuit called Motion Estimation/Motion Compensation. Unfortunately these circuits all introduce an artifact that causes film based content (movies, and some TV shows) to look like video (also called the Soap Opera Effect link). While some viewers like it, others hate it. Most TVs can shut off the ME/MC circuit, however the motion blur will return. The effect is worst with 240 Hz sets, and potential buyers should see if it bothers them. Plasma TVs have high motion resolution without needing this circuit or a higher refresh rate.
7) Buying a thinner TV for the Best Overall Picture Quality
TV thinness has no positive effect on picture quality, and can actually create image issues that thicker LCD or LED sets dont exhibit. This can be in the form of brightness uniformity, either with dark scenes, bright scenes, or both (check out the CNET link posted above). If you plan to keep the TV on a table stand, why pay more for thinner when the stand is going to be at least 9-inches deep?
8) Buying An Expensive Extended Warranty
Todays HDTVs are very reliable. Most problems, if any, occur within the first year. This period is covered by most manufacturers warranties. Extended warranties add 10% to 25% to the cost of a new set. At HD Guru we do not recommend them as we believe they are a bad value. An alternative, using the right credit card will get you another full year warranty for free. For detail see our Extended Warranty article here.
9) Not Getting The Right Features
Todays HDTVs have more features than ever. In addition to the backlighting and higher refresh rates (120, 240 Hz) mentioned above, the most common new features are 3D capability and Internet content streaming. 3D cannot be added on with an accessory later, it must be built into the set. Todays HDTVs with the best 2D picture also happen to have 3D capability.
Internet connectivity for streaming movies, TV programs, and numerous new applications can be a built-in feature or adding in the future with a Smart TV add-on like the Apple TV, Roku, LG Smart TV Upgrader, or Logitech Revue.
Thanks for the info. How good are LG hdtv’s?
I just heard today people were stealing water meters from in front of homes to sell for scrap at 4.00 a piece. The
world is getting nuts.
Now how to add on a home theater space that will accommodate one of those babies...hmmm...
Watch for the “Black Friday” deals.
(Search “black Friday” on FR for some of the past threads.)
BTW: I always post a BF thread near the beginning of November. (The BF web sites start to post the Thanksgiving bargains around the end of October, beginning of November).
PINGING THE HDTV LIST
Why TV Makers WERE ‘Arrogant Bastards’
Washington, D.C. (August 31, 2011) — Research firm IHS iSuppli has issued a report saying only 13 percent of U.S. consumers who didn’t purchase a TV in the second quarter planned to buy one in the next three to 12 months.
The number of likely buyers fell from 32 percent in the first quarter. Even worse news for TV makers, IHS iSuppli found that 83 percent of survey respondents said they did not plan to buy a new TV in the next 12 months.
The research firm said the intent to buy is the lowest since it began asking these questions in 2010.
“The findings suggest a growing willingness among U.S. consumers to suspend — if not totally abandon — their ongoing love affair with the television, the primary entertainment device for many American households,” said IHS iSuppli analyst Riddhi Patel. “A sort of wait-and-see attitude has taken hold — whether it is waiting for the economy to improve, or for television prices to fall some more, or for the arrival of better deals that combine both reduced prices and high-end TV features.”
iSuppli said consumers who are looking to buy a new TV are most influenced by picture quality, price and screen size. New TV features such as 3D and Internet access were not considered important in luring potential buyers to the store.
The research firm surveyed 45,000 U.S. households.
If the iSuppli numbers accurately represent reality, TV makers should not be too surprised. They are responsible for creating this problem.
The idiot TV makers spent an enormous amount of time and money from 2010 to early 2011 trying to get people to buy a television they didn’t want in the first place. Consumers were turned off by 3D TVs from the start, but the TV makers kept pushing them in commercials and retail displays.
Consequently, people who normally might be in the market for a new set didn’t like what they were hearing regarding new models. Instead of being told the new sets would deliver the best picture they ever saw, they were told they would have to buy a set of 3D goggles and watch 3D programming that might make them sick!
No wonder people are not planning to buy a new TV!
To make matters worse, the TV makers have tried to peddle these ridiculous 3D sets with the economy sagging and most people already owning relatively new TVs because they just bought one to be ready for the 2009 Digital TV Transition.
Foolish. Foolish. Foolish.
In January 2010, I called the TV makers “arrogant bastards” for thinking they could sell 3D TVs in this environment. With 3D TV sales numbers dropping even lower in 2011 compared to 2010’s disappointing debut — and now the iSuppli study saying people are less interested in buying any new TV — I believe my “arrogant bastards” characterization was quite apt.
The TV makers need to admit defeat, dump 3D, and start giving consumers what they really want:
A better picture!
I agree. I might also add that based upon what the content providers are providing I am not having much urge to spend any money on a new TV. The content providers have so greened up the weather channel it is not even worth watching except on the 8's.
If the trend continues will this be a future promotion? Buy 4 pairs of 3D glasses and get a FREE 3D tv.
I am actually thinking of getting one of the new plasmas; just not in 3D.
I’m not sure I agree on the comments about 3D. I recently bought a 47” LG LED/LCD model. I bought the TV because it was recommended to me by someone at work, and the price was fantastic. I could not possibly be more happy with the TV at this price point.
It has 3D support, which was not something I was looking for, but since it had it, I tried it out. It does not use the expensive active goggles - rather they are very inexpensive passive glasses, and the TV came with 4 of them. I’ve watched a few 3D movies, including Avatar, and have enjoyed it.
By the middle of October, I plan to buy a new plasma. I’ve been targeting the Panasonic ST30 50 inch set based on recommendations from Home Theater and Sound & Vision magazines. I have absolutely no interest in 3D (especially having to purchase four sets of glasses!!) and could save $300 by going with the non-3D S30 model. However, the ST has a better picture and black levels- which is what I really want. So, unless I convince myself that price is the biggest factor, I’ll soon be counted as propping up the 3D sales figures. I can’t believe I’m the only one in this position.
I have also read that the 3D sets have better 2D picture. I may do the same; only with no 3D glasses.
I cringe when I see oversaturated colors, blown whites, crushed blacks and too high/cool (blue) a color temperature people get using presets.
How and why to do it is explained here, LCD TV Calibration.
I use Digital Video Essentials DVD, Spears & Munsil High Definition Benchmark Blu-ray Edition and a Spyder3TV calibration puck and software, any of these will get you in the ballpark and calibrating from one source will improve all sources.
Get one of these and save yourself the bother:
You say a 5” isn’t big enough? Sit closer...
the new plasmas are a whole different world from the first ones. I have one of each... A 42” Hitachi from the first generation and a 54” Panasonic from the new generation. From my eye, plasma still has the brightest, fastest picture out there. The new ones don’t suck electricity like the old ones, either.
Currently, I’m a big fan of the Panasonic line.
