Flat Screen Hd Tv - Tips for purchasing a flat screen hd tv

Making the decision to purchase a flat screen hd tv is one that can be both exciting and intimidating. Top of the line, sophisticated and cutting-edge technology can seem confusing and overwhelming to the average consumer. It can be difficult to make sense of the language being used to describe the features and functions of the TV, which can make it tough to make an educated decision on which brand and model is the right choice. Listed below are some items to consider before purchasing a flat screen hd tv.

One of the first decisions that will need to be made is whether you will choose to go with plasma or LCD for your new TV. Each of them has their own lists of pros and cons which will need to be considered prior to making your purchase. Listed below are a few of the features that each offers:

Plasma:

• Typically unavailable in sizes smaller than 37 inches.
• Uses phosphors to generate light which can, in some cases, result in “burn-in” images. This can happen when any single image, such as a network logo, remains on the screen in the same location for a prolonged period of time. The risk of burn-in has dropped significantly as the technology has advanced.
• Certain models are strictly visual and do not include speakers nor TV tuners.

LCD:

• Offers a broader range of sizes than plasma with options as small as 15 inches.
• Slower response times than plasma can cause blurring in fast moving action scenes, such as video games and sports. As the technology advances, this problem has become less frequent.
• Work well in almost all conditions, including brightly lit areas which are not ideal for plasma
• Immune to burn-in

Options and specifications can vary widely depending on model and manufacturer as well. Knowing the proper terminology and how it will impact your viewing experience can help educate you for making the right decision with your flat screen hd tv. Here are a few of the more important specs and what they really mean:

Contrast Ratio:

• The contrast ratio simply describes the darkest and brightest light that can be displayed simultaneously. The higher the contrast ratio is the better the quality of the picture the TV can produce.

Aspect Ratio:

• The aspect ratio defines the relationship of the width of the screen and the height of the screen. Older TVs have 4:3 aspect ratios while wide-screen displays have 16:9 aspect ratios. HDTV is in wide screen format as are most DVDs, so the 16:9 ratios are likely to provide you with the best viewing experience.

When looking for a new flat screen hd tv it is also important to consider the peripheral devices you hope to use with the TV. Most people have other equipment that they use in conjunction with their televisions, such as DVD players, video games consoles and surround sound systems. For these devices to work properly, you will want to make sure your new TV has the appropriate inputs. Here are some of the various inputs and what they may be used for:

• Composite video – this is the lowest quality input, but has the broadest range of uses. All video devises include composite video.
• S-Video – offers better quality than composite video and is available on most video sources. Connection is made with special cable and multi-pin sockets.
• Component video – this is the minimum standard for connecting HD cable and satellite receivers as well as progressive scan DVD and Blu-ray Disc players.
HDMI – High Definition Multimedia Interface – this is the most dominant connection for HDTV today. It combines the simplicity of a one wire connection with top of the line video and audio. It is best to look for a model with multiple HDMI inputs since the trend for new technology is geared towards HDMI compatibility, so the more you have available, the easier it will be to hook up your new TV to your other devices.

It is important to remember that everyone has a different set of requirements for their televisions. Make sure you have clearly defined yours before making the move towards a purchase of a new flat screen hd tv.
