High Definition vs. Standard Definition

Before we begin, we need to establish a couple of basic terms. The HD in HDTV stands for high definition. In comparison, those old boxy TVs that we grew up with are standard definition, (SD), though they were never called that because there was no HD.

Without be too technical or exact, the picture that we see on a TV screen is made up of thousands of little dots called pixels. SD TVs use fewer pixels to create a picture, which means less detail - or definition - than an HDTV. More definition translates to a sharper, cleaner, finer image - a "honey come look at this" humdinger of a picture.

Representation of 1080p, 720p & 480i - More Pixels = Sharper Image

Definition for TVs is stated in terms of resolution. When you go shopping, you will probably run across these two common resolution numbers, 720p and 1080p. As you would guess, a 1080p TV uses more pixels than a 720p TV. Both are considered high definition TVs. (For comparison, standard definition is usually stated as 480i or 480p. I don't even want to get into i, interlace, and p, progressive.) I will discuss resolution as a factor in choosing a TV later.

To an extent, buying TVs in 2009 is easier than it used to be because almost nobody makes standard definition TVs anymore. If you go into a store, you really have to search for them. So if you are buying a new model TV, about your only choice is an HDTV. In a couple of years, we will simply drop the HD tag and go back to calling them TVs.


Picture Quality - Minding Your P's & Q's

For me, the foundation for judging any HDTV is picture quality, which cannot be reduced to one characteristic like sharpness or contrast or color. Picture quality is a combination of all those and more. It's the gestalt.

When you experience great picture quality, you'll nod your head and think, "Damn, that's what all this hubbub about HDTVs is about."

The problem is that picture quality is subjective. For example, I'm particularly sensitive to overly colorful skin tones, so a pleasing picture to me may seem way too desaturated to you.

In my reviews, I will give you my opinion about a TV's picture quality, but you're the one that has to live with your choice. And the real fly in the ointment is that it is really difficult for you to judge a TV's picture quality by strolling through the HDTV aisles in a big box store - even harder online.

If you can, I would suggest that you carry your favorite DVD with you and find a store that you can play it on a few TVs. If nothing else, get your mitts on the remote control and take the TV for a spin around the Setup menu. I know that idea causes dread in the hearts of salesmen; but if you are seriously shopping, then they should be glad to help.

One last thing before we move on. This is a guide. I will not tell you which specific HDTV to buy. There are way too many HDTV models out in the marketplace and I only feel comfortable recommending TVs that I have reviewed. If you want specific suggestions from me, look for the Highly Recommended logo on a review.


Price

Let's continue this HDTV Buying Guide with what is often the major consideration in buying an appliance - cost. For most of us mere mortals, we need to decide how much we want to spend. Without some dollar limit, strolling into the HDTV section of the store (whether brick and mortar or online) can lead to a major household budget buster.

I'll discuss price of TVs in terms of screen size, screen type, and screen resolution in the following sections. For now, let's talk about cost, near term and long term. Beyond the price of the TV, before you leave the store you will be accosted with a few other expenses that you should factor in - cables, wall mounts, transportation, installation, and warranties.

Rather than dive into a long discussion on cables or wall mounts at this point, please see the Accessories section at the end of this article.

If you are buying at the local big box store down the freeway, you will have to transport that lovely toy to your house. And if we're talking about any screen much larger than 32", its box probably won't fit into your Prius. It may not even squeeze into your Escalade. Hopefully, you have a good friend with a strong back and a cargo van.

If not, you may want to consider using the store's delivery and installation service. Often installation is priced reasonably and packaged with the TV as an incentive. Do the math, only you can to decide if it is worth it.

Of course, if you are purchasing online, then shipping to your door will be calculated into the final price. Unless it is otherwise stated, don't be surprised if the delivery man tells you that there will be an extra charge for maneuvering the box into your TV room or upstairs into the bedroom.

Most retailers will try to sell you a warranty that can amount to a sizeable chunk of change. The general consensus is that warranties are not a great idea when it comes to TVs. You can read more about warranties in an article. "What's with Warranties?"

Finally, depending on your disposition, when you are buying a big ticket item like an HDTV, negotiation opportunities may arise. With intense competition, the profit margins for retailers on the TVs are fairly thin, but you may find some wiggle room, especially on prices for warranties and installation.

Size Up Your Screen.

Size up your tv screen

After you have your budget squared away, you need to decide how large of a screen you want. Usually, the largest screens cost the most, but regardless, the TV should deliver the right-size picture for where you'll sit relative to the screen. Sitting closer to a smaller TV means you won't have to spend as much on a big screen. But if you sit too close, the picture will look poor.


Wide-screen TV-viewing distances
Nearly every TV sold these days is a wide-screen HDTV, so the chart below only applies to those sets. If you have a regular TV that's not wide screen, the rule of thumb is that you should sit no closer than twice the diagonal measurement in inches. Wide-screen televisions showing high-resolution DVD and HDTV look better than regular sets, allowing you to sit closer and experience a more immersive, theater-like picture.

With wide-screen sets showing DVD or HDTV, you can sit as close as 1.5 times the screen's diagonal measurement and still not notice much of a loss in quality, while sitting farther away than three times the screen size means you're likely to miss out on the immersive feel. Here's a rundown of minimum and maximum recommended viewing distances for wide-screen sets.

Size and your room
Generally, 30-inch and smaller sets are great for bedrooms or guest rooms but too small for the main living room. Sets with bigger screens are large enough for the whole family to enjoy and will probably be too much for most small bedrooms.

If you're mounting the set inside an entertainment center, be sure it fits in every dimension; also, leave a couple inches on all sides so that the TV has enough ventilation. If you're getting a bigger set, you may want to consider a dedicated stand. Many such stands also include space for your TV-related components, like cable boxes and DVD players.


Screen sizes and display types
CRT tube televisions are a dying breed, and new ones you'll see generally max out at 27 inches. Flat-panel LCDs can range anywhere from 5 inches to more than 100 inches diagonal; plasmas are between 32 and 103 inches; and rear-projection sets start at about 50 inches and go to as large as 73. These different TV types have their own strengths and drawbacks, which we detail in "Four styles of HDTV."

Samsung LN37B650 Lowest Price







Read below Reviews before BUY!!


The most helpful favorable review :

Amazing picture quality!! Thrilled with my purchase!, May 3, 2009

I was hesitant to buy an LCD TV because so often they seem to have such poor contrast, have lot's of visual artifacts and look horrible with fast moving scenes. However, Plasma technology is all but dead and there are no 37" Plasmas anyway. So I decided to look at high end LCD's.

I saw the Samsung LN37B650 at a local electronics store (for $300 more than the price on Amazon) and side-by-side it looked head and shoulders above all the other 37" LCD's in the store. After doing more research online and comparing specs, I decided upon this TV.

Amazon delivered to my home in Los Angeles in 5 business days through a delivery company called "Pilot". The delivery arrived exactly within the appointment window I scheduled with Pilot, and the box and merchandise were in perfect condition.

I connected the TV to my HD cable box with an HDMI cable. HD picture quality is immaculate. I never could see the picture quality in SD at the local store, so I was surprised and thrilled to see that in SD the picture is every bit as good as my reliable CRT that this TV replaced. The SD picture on my 50" Sony KDS-50A2000 does not compare to the excellent SD picture on the Samsung.

My only complaint is the lack of a printed manual. At these prices, Samsung shouldn't have gone cheap by neglecting to add a paper manual. Having to review the manual on the TV is a pain.

I could've spent ½ the price on a cheap 37" LCD, but would've hated the picture. I think in this case, the saying "you get what you pay for" holds true. I am glad that I spent more to get what may be the best possible picture quality in a 37" LCD TV.

 Excellent picture, AutoMotion settings annoying, May 18, 2009

Purchased this a few weeks ago. The image quality is excellent. The 120Hz eliminates the 3:2 pull down you'll see when watching movies. However, there is an interpolation mode that generates the extra frames, attempting to reduce motion blur artifacts.

The irony is that while it looks great in many instances, it can generate artifacts in fast paced sporting events (though most of the time this is fine). Also, if you watch movies, the film tends to look like a soap opera video quality until this is switched Off (eliminating the motion blur makes the image really clear and strangely too much like video).

You can set this Off but it is nested under three menus and I cannot seem to save this setting. Very annoying when it kicks in during a movie. This setting does not appear to save correctly so I find I have to switch it Off as a go back and forth between HDMI sources. I am hoping a firmware fix can correct this in the future.

Some other annoyances:
*lack of headphone jack (you will need to get an adapter)
*if you want to use the "buttons" on the set itself, they are solid state and hard to find on the surface of the TV
*no physical manual; digital copy on USB key that is included

Pros:
*excellent picture quality (when the correct settings are chosen)
*lots of ports
*nicely designed frame
