Specifications for ignoring
Current specifications of HDTV are full of confusing information, and much of it is worthless to be honest.
Refresh rate eg 60Hz, 120Hz, 240Hz, 480Hz, 600Hz - These numbers, which are supposed to refer to the number of times that the still image on the screen is updated (60 Hz = 60 times per second), have proliferated in the last few years.
Resolution as 720p, 1080p, 4K-Almost all televisions today is a 1080 model, but in some smaller screen sizes of LCD and entry level plasma series can still find 720p models. Nothing wrong with a resolution of 720p.

Energy Star-No number normally associated with Energy Star specifications TV Almost all available for sale now qualify for Energy Star, which makes the certification useless for comparison purposes.
The basic characteristics to consider
Now you know what to ignore in HDTV spec sheets, it's time to take a look at what is important. The following are the important features to evaluate:
HDTV Inputs: One of the most important thing here is to have enough HDMI inputs to connect all devices. Each HDTV must have atleast three HDMI ports. The reason, if the main TV room can have cable or satellite box, game console and Blu-ray/DVD player.
Screen fit and finish: with today's most HDTV only basic options of matte or glossy. The effects can be seen in the showroom, especially when the HDTV is displaying darker material. If you do most of your observation in a bright room, a screen that reduces glare is a good thing. Some HDTV has a small bevel which also adds to the perception of viewing.
Remote Control: The remote control that comes out of the box is very important. If you do not plan to use a universal remote control, then clicker including HDTV is what you will use every day. The recommended TVs include preference for medium-size remote with backlit buttons.
Ease of use: Your HDTV must have explanations menu systems with integrated multi-screen selections. It should be easy to use and useful is the creation and ongoing use. If this is too confusing, you need to be considered for continued use.
Energy efficiency or not: As mentioned earlier, the Energy Star ratings are worthless for comparing different HDTVs. It is also true that a more efficient HDTV generally will not save much money on your electric bill. However there are still some significant differences between energy use HDTV types eg typical plasma TV can consume twice that of conventional LCD.
What are the additional features that you may need?

LED Backlight: LCD TVs that use standards-based technology LED backlight that can cost more than those with standard fluorescent (CCFL) backlight. LED does not do much to affect the image quality. They use less energy. Using LEDs can also allow manufacturers to reduce a few inches thick of HDTVs "general.
Buy online
If you like the comfort and the ability to shop online, you have to choose a provider with a solid return policy. There are many vendors of crap out there that do not allow any returns on HDTVs. Some online merchants can make you pay the return shipping and a restocking fee, provided they accept returns on TVs at all. Solid online sellers like Amazon, offer free return shipping and do not charge a restocking fee. It is a well-respected online retailer.
