The technology of LCD has been in the market from few decades; however, it is only recently that there is home entertainment introduced through a flat panel LCD TV sets.

Comparing LCD with the Plasma in the field of high definition, we can say that LCD is much wider as well as more popular segment in the market than that of a Plasma TV. One of the main reasons is that you can find even the 26-inch and 32-inch screen size TVs in the LCD segment while you can not find Plasma in this range.

There are wide ranges of models of LCD TV in the market today with various features. Competitions between various brands are really good for the consumers, because more the competition, lesser the prices, and bigger the ranges.

Here are few buying guides for a LCD high-definition TV:

Until recently most of the big flat screen TV could only be seen in Plasma, but now there are many 52-inches LCD TV in the market.

As LCD technologies are more established now, we find it cheaper than most of the same size plasma television. The technology of LCD is more favorable in supporting 1080p or the full high-definition images. The colour depth and the brightness of a LCD are more vibrant than that of a Plasma TV.

1080p Resolution

All televisions which are marked as ‘HD Ready’ are capable to receive and display a high definition signal. It doesn’t matter whether the high definition signal are coming from different piece of equipments such as a Blu-ray player, or a DVD player, or from any digital broadcaster. The main thing is the resolution. The resolution must be at least 720p, technically which means 720 vertical lines and 1,280 horizontal lines of resolution by a method known as ‘progressive scan’.

The sets which are capable of receiving or transmitting 720p can also take any other broadcast which may be delivering 1,080 horizontal and 1,920 vertical lines of resolution. However, it delivers through a low quality ‘interlaced’ method, which is also known as 1080i.

The similarity to 1080p with 1080i is that both deliver the same 1920×1080 signal resolution, however the methods are different. 1080p uses progressive scan method. This factor makes 1080p high up in the quality queue and is also labeled as ‘Full High Definition’.

Naming technologies

Competitions between the LCD manufacturers are so high that each company wants to make big attractive names to some technologies they used in the picture processing or others. Then they start marketing their product based on those exciting names of the technology in order to attract the customers.

It is always recommended to read reviews of the product before buying, because technology names may sounds better, but you don’t know the reality.

Good connections

Your TV will not be completed without the accessories that you may have to buy like Blu-ray player, speakers, or some Sky box or cable TV connection. Let’s suppose your cable TV provider is offering few high definition channels. However, the quality of the signal of those channels is wholly depending upon the quality of the cable you are using in between your cable box and your television.

For High definition TV and channels, a good quality of HDMI cable will really make a vast difference to your TV viewing experience. After HDMI, next is the component video, RGB Scart, and S-video. For connecting your older devices to the high definition TV, you can use Scart and composite video.

At first, these are the few things that you need to know about the particular TV sets.

  • Display size
  • 1080p output
  • Contrast ratio
  • Native resolution
  • HDMI ports
  • Freeview tuner


1080p connectivity is highly in demand as of now and a very new area is developing for a high end image processing, i.e.  24Hz.  Originally the films are shot at 24 frames per second, also the high-definition Blu-ray players offers the output images at 24Hz frequencies. So the 24Hz-compliant TV will allow the best-quality of pictures preserved through out the all processes.

Dead pixels

One of the major things that you need to check is ‘dead pixels’. LCD panel consists of a huge number of very small shutters. There can be possibility of such dead pixels in your brand new television. As a consumer you must check for any permanently light or permanent dark area, which completely depends on whether the shutter is closed or in open state. If you found 2 dead pixels in million, your set is faulty and legally you can demand for a replacement.
