LCD HDTV has become a trend in the home entertainment industry because of its sleek and thin design. It has gained recognition because of its innovative features and impressive picture quality. HDTV manufacturers continue to progress and modify the good features and make it even better. However, regardless of the development, the consumers are given an option to purchase a good LCD HDTV at a very reasonable price, which suits their lifestyle and needs. Here are some pointers to consider in choosing an LCD TV.

When you shop for a television, first thing that you would probably ask is the resolution. Nowadays, 1080p resolution is the best for consumer home theater. Some companies promote a 1080i LCD HDTV that has an actual widescreen resolution of 1,366 by 768 pixels, which greatly differs from the 1080p. 1080p resolution has 1,920 by 1,080 pixels.

Sometimes specifications that are worthless like contrast ratio and pixel response time. These specifications are problematic because there are many variations and each is calculated in notably different ways. Sales people tend to focus on whatever specification calculation offers the most impressive looking result.

Regarding pixel response time, what you need to know is if a particular LCD TV is optimized to reduce the smearing of an image when showing a fast motion video. Currently, the 120-Hz display technology is the feature that best addresses this problem. It is a premium LCD feature but its advantages are instantaneously recognizable.

Contrast ratio is the ratio of measured light output when displaying white to its measured light output when displaying video black, also called the black level. There are several types of contrast ratio calculations. These are sequential, intra-frame, and dynamic. But these calculation results are often useless when comparing one LCD HDTV to another. It is better to focus on which model makes the deepest and darkest representation of video black because the LCD TV that has a darker black level has the more detailed, enhanced saturation, and more appealing image.

An LCD HDTV screen can produce more than twice the light output of a Plasma TV. The extra brightness that an LCD HDTV can provide helps in maintaining picture detail by improving the dynamic range of the image in a well-lit environment. To minimize distracting light reflections, a lot of LCD HDTVs have a matte finish. However, there are some new LCD HDTVs that are incorporating glossy top filters that enhance apparent contrast and color saturation by making video black appear pitch-black dark. Glossy LCD screens make a slightly crispier picture than a matte finished outside filter can produce.

An LCD TV produces a picture by channeling the output of a very bright backlighting system through a series of optical filters. The capacity to control an LCD TV’s backlight can help minimize eyestrain in a dark viewing environment. In addition, the brightness level of an LCD HDTV’s backlight correlates to its power consumption. Lower backlight output to dark-room viewing levels can result in one-half to two-third less power consumed. Also, lower backlighting extends the lifespan of the lamp module.

Lastly, you should consider video port needs, particularly HDMI. High-Definition Multimedia Interface is the standard for digital video transfer in home-theater. The main benefits are the clarity of a digital signal and the audio and video that are streamed over a single cable connection. Common appliances that can be connected to an LCD HDTV through HDMI are DVD players and game consoles. Most LCD HDTV provides two to four ports.

Look for these different features when you are purchasing an LCD HDTV. This technical knowledge will help you decide which LCD HDTV meets your needs.
