The Facts About DLP VS Plasma TVs

January 25th, 2010
Jim Johnson asked:


With advancing technology revolutionizing the television viewing field, consumers have more choices than ever before. And as is often the case with electronics, it can be confusing. Terms and acronyms are used in the electronics industry that you just don’t find anywhere else, and if you aren’t careful it can keep you from buying newer technology simply because you don’t understand it well. That can certainly be the case with modern TV monitors.

The old analog TV sets of yesteryear did not have to have a very advanced monitor because the TV signal was only so good anyway, So CRT monitors lasted as the screen choice for decades. But now with HDTV moving the entire viewing experience forward in dramatic fashion, better ways of producing the on-screen image is in full production.

Two of those competing screen technologies are plasma TVs and DLPs (digital light processing TVs). Both types of screen technologies have been around for a while, although DLPs have only become commonplace in recent years. They use completely different means of displaying a TV picture and so each has it’s own peculiarities, both for good and bad. So you as the consumer need to weigh the differences and determine which will best fit your own needs.

Plasma TVs are well-known for their high contrast images and vivid colors, and they are generally cheaper than DLP TVs in the larger screen sizes. They have a wide viewing angle, and would make an excellent choice for many people. The drawbacks include less longevity and faster wear rate at higher altitudes above 6,000 to 7,000 feet, and the fact that they tend to run hot and need internal fans to cool them down that can sometimes be noisy depending on the model that you choose. They also can suffer from screen burn-in when an image is left on the screen for a very long time, producing a faint ghost image even when viewing something else.

DLP TVs are are capable of painting the screen with high contrast, color dense images too, although the nod still has to go to plasma TVs in general in this area. They are also easily used as a monitor for almost any digital video source that you have, including your computer. They use a reflective technology to display the screen image and so their picture is very bright and easy to see even in brightly lit rooms. However, they must be viewed at eye level, since the brightness falls off rapidly as you view them from either above or below eye level. The DLP will last almost indefinitely, but the light source must be replaced every 10,000 hours and that will cost over $200 when you do.

Actually either will make a fine choice to use with today’s emerging television technologies. Just be aware that each has it’s own drawbacks, so choose the monitor that will fit your own particular needs and uses best.



Buyers Guide to Home Theater Projectors

December 24th, 2009
Warren Thompson asked:


Over the years, I have grown really attached to my home theater system. I must say, of all the rooms in the house, my own little movie theater is the one I could not live without. I am absolutely in love with my home theater system and, if you are anything like me, I am sure you will love yours too. I found, when I was initially building my system, that there was so much information to absorb. Every product out there seemed better than the next, and I found myself unsure about which to buy. Here are a few things to keep in mind when shopping for a new home theater projector.

There are two main types of projectors on the market; DLP and LCD. DLP stands for digital light processing. It was invented by Texas Instruments, and utilizes a microscopic array of over 2 million mirrors. DLP has a higher contrast than LCD, but there are some unfavorable consumer reports that note something called the “rainbow effect”. The “rainbow effect” is noticeable when looking from one side of the screen to the other, and is characterized by a sudden burst of color.

LCD stands for liquid crystal display. These projectors have three distinct glass LCD panels inside; one for each component of the video signal (red, green, and blue). While DLP chips reflect light, the LCD panels allow light to pass through them. LCD projectors produce brighter images, and they are known for having excellent color saturation. In the end, you will be hard-pressed to notice a great difference between the two types of projection systems.

When shopping for a new projector, keep your particular needs in the forefront of your thoughts. As I mentioned above, it is really easy to lose yourself in the minutiae of each particular system. Connectivity is a definitely something to be mindful of. Make sure that you are able to connect all of your components, including your gaming system. Nothing beats playing Halo in real-life size! Contract ratio is another important factor; the higher the ratio, the better the picture will be.

The brightness of your projector is another thing to consider. Light output is measured in ANSI (American National Standards Institute) lumens. You will want to avoid a projector that produces anything shy of 1000 lumens. As you are likely aware, the projection resolution is extremely important. This refers to the number of pixels that can be displayed on the screen. Go for something that is no less than 1024×768, as this will allow you to fully appreciate the depth and quality of HDTV. In the end, you should buy the projector that is in line with your needs and your budget. Soprano’s is coming on right now! Time to go!
