Q. I'm planning on buying a new TV soon, but there are so many display options. I don't know too much about the difference in LCD, LED, and Plasma. I know that one of them has like a light shining off the back or the side of the TV and thats the one that I don't want. Can somebody help me with this information.
A. For many years, the CRT technology was the dominant technology in television sets. However, in the past few years, there has been a significant improvement in the technology, which has seen the introduction of LCD, plasma and LED televisions. Each of these new technologies has its strong points in the method that it displays images, among other features. The features for each type of these technologies are as below.
As with most electronics, it is recommended that you first do your research before choosing a HDTV. By doing research, you can ensure you choose a quality television that you will enjoy. There are many different sites that post reviews, and reviewing what other customers have said is really important. A good example of a page is one that displays Panasonic Viera TC-P54G25 reviews. Such sites not only provides expert reviews, but more importantly, also supply customer reviews.
When researching a television, it is also important to look at the differences in the technologies. The next few section outlines the three technologies that you will find in a HDTV.
What is an LCD TV?
The acronym LCD stands for Liquid Crystal Display. This technology was created to replace the CRT technology. A LCD TV is a significant improvement in the way pictures are displayed due to the mode of display involved.
LCD technology uses two major components to display, namely; Cold Cathode Florescent Lamps or CCFLs and molecules of liquid crystals. The CCFLs are used to illuminate the liquid molecules with white light, and as the light passes through, an image is created.
A LCD TV has the following advantages over a CRT TV; flat and much lighter, a higher resolution, wider viewing angle of up to 175 degrees, lower power consumption, resistant to ‘burn in’ due to static images, and are ideal for naturally lit environments. However, there are some disadvantages to this technology such as a low contrast ratio and inability to achieve true black picture quality.
What is a Plasma TV
The shortcomings of LCD TV led to the development of Plasma Display Panel, otherwise known as a plasma TV. With this technology, images are created from gases containing neon and xenon atoms.
Plasma TV technology boasts of a rich variation of colors, due to an advanced color generation feature, that is able to generate true black picture quality.
The viewing distance and angles are also wider, ranging from 160 and up to 180 degrees, which is more than what can be achieved with a LCD TV. A plasma TV also has a higher lifespan than LCD TV. The downside of this technology is that the viewing capability, especially the brightness is greatly diminished in poor lighting conditions, lower resolution, and an irreparable back light.

How to get the best picture out of my 120hz LCD?
Q. I bought a 46in Samsung 120hz LCD(LED backlit) HDTV, so far at times it does seem better but there is still ghosting with the black and dark colors, the faster the picture, the more distorted and blurry it gets. Any help would be greatly appreciated. The model number is LN46C650L1F.
A. Sadly - motion blur is inherent in LCD panels with fast moving objects. The "120 hz refresh" cuts the problem in half compared to a standard 60 hz refresh model, but it is still there.
Some models have software 'enhancements' that try to smooth out the motion blur, but this sometimes causes other artifacts.
All new televisions should have their Brightness, contrast and color set to sane levels. (These are set at the factory to ultra-bright so the unit will be eye-catching if used as a demo on a bright display floor).
Get a Pixar movie and go to the disk setup menu. You will find test-patterns and instructions for properly setting the brightness, contrast and color.
This will probably reduce how noticeable the ghosting and blur are, but it will not solve it.
