Getting Better Television

Samsung DLP TV

>If you’re considering the purchase of a new television, a Samsung DLP TV could very well be exactly what you’re looking for.

It was just a short time ago that many people wouldn’t consider a projection television, just because it was, well, projection. Those days are long gone and Samsung is creating some excellent DLP sets.

The Samsung DLP TV models being released are using the latest version of Texas Instrument’s amazing DLP (Digital Light Processing) technology. This writer still owns an Hitachi rear projection set that utilized the first version of this incredible technology. Although a detailed explanation isn’t the purpose of this article, the original DLP setup used a rotating color wheel, and this color wheel was the source of the much dreaded rainbow effect. The anomaly seemed to be more of a problem for the hardcore video enthusiasts however, some people barely noticed it. Personally, it was never a major problem on my older Hitachi, for me anyway.

Regardless, Samsung has eliminated even the chance of having the rainbow effect being a problem. The new Samsung DLP TV models have no color wheel. What else is great, unlike the past versions of DLP, there are also no more high-powered arc lamps to replace. Since the light source is now solid-state LEDs, you won’t have to worry about spending the, potentially, several hundred dollars for the lamp replacement every few years. Also, since you’re not powering the previous lamps, causing much wasted energy in the form of heat from the lamps, you can actually save money with the new Samsung LED TV models.

I really believe the elimination of the (rotating) color wheel, and the inclusion of the LEDs as the light source, would have been more than enough for this writer to upgrade, but there is more to the new Samsungs.

One other thing that stands out is the contrast ratios now being realized. In the past, most DLP sets had fairly poor contrast ratios, often measured in the hundreds:1. Now, the Samsung DLP TV models are measured in the hundreds of thousands, and even millionths to 1 contrast ratios.

Combined with much brighter images, a broader color gamut and excellent Internet integration, Samsung is creating some truly fabulous HDTVs.

If you’re exposure to rear projection television was some time ago, don’t discount a projection television until you’re experienced the technological masterpieces that Samsung is releasing.

These aren’t you parents rear projection television.

How to Hook Up Your Computer to Your TV

>In this article, we will look at the different ways in which you can hook up your desktop, laptop, or netbook computer to your television and the reasons that you may want to do this.

Most of us have a computer at home. And, most of us have a television in our living room. For the majority of us, the television in the living room is much bigger than the monitor that we have for our computers. Many think this and ask: “Is it possible to connect my computer to my TV?”

Aside from the sheer size of your television, there are also many other reasons that people may want to connect their computers to their television sets. For example, now-a-days most people store all of their photos on their PC. Thus, what do you do if you want to show a room full of people your photos? For that matter, what do you do if you want to share your vacation videos with all of the people gathered in your living room?

You get the picture? You have a lot of data in the form of music, movies, photos, and more that would be better viewed on the LCD TV in your living room than your skimpy monitor that is attached to your computer.

So, is it possible to connect your desktop or laptop computer to your new television to accomplish all this? You bet it is and it is not that difficult. There are four ways that you can do this.

The first method is the old way and I do not recommend it. This method involves connecting an S-Video cable from your computer to your television. Old computers and older televisions often had an S-Video port on them and this was the only way to connect the two. The visual and audio output on the TV was not optimal. This inadequate solution now is not available for most people anyway as S-Videos ports are no longer a standard.

The method that will almost certainly work for everyone is a male VGA to VGA connection. The reason that this will work is that nearly all computers and all LCD TVs have this type of connection. This is the connection that I currently use and the picture is fantastic. For audio to come out of your TV or stereo, simply get a stereo mini phone jack to dual RCA jack stereo cable.

Your final two options are even better. DVI and HDMI. These are the best digital transfer mechanisms. Many people, however, have a problem with this because their computer or LCD TV does not have one of the two connections. Many computers have DVI but not HDMI. Almost all of the best LCD TVs have HDMI but sometimes not DVI.

Not to worry. If your computer has DVI but your LCD TV does not, you can buy a DVI to HDMI converter to connect your computer with your TV. You will still need to run the audio separately as DVI does not carry audio.

Your most optimal connection of all of them is HDMI to HDMI but this is only possible if both your computer and LCD TV have HDMI. Make sure that you are not be swayed by people trying to sell you an expensive HDMI cable. They can be had for around $10 so don’t pay more.

In summary, connecting your desktop, laptop, or netbook computer to your LCD TV is pretty awesome because it allows you to view, and listen to, all of your computer media on your big screen or home stereo. I fully recommend it!

Learn How a Rear Projection TV Works

>Rear projection television or RPTV is the technology behind the modern day large screen television display and until recently catered to consumers as the only option for an affordable large screen TV experience.

Magnifying Details – How Does a Rear Projection TV Work?

As the name implies, RPTV uses a projector to magnify a small image from the video signal onto a large screen. The projector uses a bright beam of light and a lens system to project the image to a much larger size. The traditional TV setups are in some ways similar to the RPTVs. The television box contains the projector inside and the projector projects the image form behind the screen.

Different Projection System for RPTVs

CRT Projectors

The earliest RPTV technology, CRT backed RPTVs were the first to exceed 40 inch screens. They were bulky and the picture was unclear at close range.

DLP Projectors

A DLP projector creates an image using a DMD chip, which on its surface contains a large matrix of microscopic mirrors, each corresponding to one pixel in an image.

LCD Projectors

In these RPTVs, a lamp transmits light through a small LCD chip made up of individual pixels to create an image.

RPTV Faces Stiff Competitions from LCD and Plasma

The weight of earlier RPTVs required it to be wall-mounted, and though most consumers don’t wall mount their sets, the ability to do so is considered a vital selling point. The modern-day rear projection TVs have a smaller footprint than their predecessors and the recent models are lighter. But RPTVs still fall short compared to the latest LCD and plasma flat panels which are lighter with superior picture resolutions.

While popular in the early 2000s as an alternative to more expensive LCD and plasma flat panels, the falling price and improvements to LCDs have led to Sony, Philips, Toshiba, and Hitachi planning to drop rear projection TVs from their lineup. Currently, Samsung, Mitsubishi, ProScan, RCA, Panasonic, and JVC RPTVs remain in the market.

Answer to the question: I was cleaning the bulbs on my television and now I can’t get it to show a picture?

Many of you might be asking this same question so I’m posting with the answer here. Enjoy. The question is from Lenzi B

I have a Hitachi television. I was cleaning the bulbs and calibrating the televsion. The picture was crytal clear again. When I put the back back onto the television a clear liquid ran out from under the television. Now the t.v. will come on but the bulbs are not coming on. Any suggestions????

Answer: If you are referring to the bulbs in a projection screen tv, by having cleaned them you may have left oils from your hands or if the bulbs did not dry first before attempting to turn on the television then part of them had a different heat capacity then the rest of the surface area of the bulb. When one part of a surface area heats up faster than another they also expand at different rates causing tension. Such tension causes the breaking of the bulbs. If you are referring to electron tubes with heating elements, then the same effect would also cause them to break although cleaning them superficially would have no effect upon their operation so I should probably conclude that you have a projection screen TV with now broken bulbs due to tension cause by thermal differences.
