Guys, you may want to cover your eyes for this bit of information. The plasma TV was not developed by men wanting a better viewing experience for their favorite sports. There, the truth has been let out of the bag, so to speak. It is incredible that the plasma based viewing device is not a new idea. It has been around for quite some time. Perhaps a bit of a history lesson is in order for you to understand how this application came to be available for the masses.

It all began in 1964 at the University of Illinois. At this time, computer monitors were simple televisions. You have to realize that the televisions at this time were cathode ray tubes.

They had to continuously refresh themselves in order to display correctly. That was a big problem when using a television as a computer monitor. Sure it was okay for watching tv shows, but the resolution for computers was terrible. By the end of the year the first plasma monitor was in operation.

Today’s plasma [uc]tv[/uc] has millions of cells that comprise the color and resolution of the screen. That initial plasma monitor was only one cell. However, it was still a step in the right direction. There was a set back, though. Liquid crystal displays became the more acceptable method and plasma technology was put on hold. Fast forward a few years and panasonic 42 plasma tv sets became widely popular.

Where would the world be without technology constantly pushing it forward? Sure a plasma TV did not put man on the moon or allow for cell cloning, but it was a huge development at the time and has greatly affected the economy. Three years ago a plasma television 42 inch wide was considered only for the rich and famous. Today, many consumers can now afford to own one of the panasonic plasma tv technological marvels.

Thank you scientists at the University of Illinois for bringing men and women everywhere the ability to watch games on a plasma TV. Where would technology be if necessity had not demanded you devise a new computer monitor? We would probably still be watching our big screen television sets and never knowing that a clearer picture was possible at a decent price.

high def televisions are great, but they don’t always look as good as promised. Worse, the issue you’re having isn’t always under your control to fix. Here are a few reasons you may be having problems with your picture, and what you can do to make it better.

Your Blu-Ray Disk Player Is Not Compatible.

Most people planning to get a new high-def TV are also planning to pick up a Blu-ray disk player as well. You might expect all these technologies would work together smoothly - but you’d be wrong. Unfortunately, there are some serious compatibility issues with certain Blu-ray players if you don’t have the right high-def TV. Read your specifications very carefully. Your high-def TV should be able to accept external 1080p signals from a scaling media player (DVD, HD-DVD, or Blu-ray). If it does not specify this, and your media player needs to scale the picture, call tech support.

Your Cable Company Is An Ass

In most cases, your HD will work, or it won’t; there is no snow, smudging, or other in-between issue. If your HD picture looks bad, it’s probably your cable (or satellite) company’s fault. HDTV signals need to be compressed to be broadcast properly, but they can be compressed too much. If your company uses a channel intended for only one data stream and squeezes two or more into it, your picture quality will almost certainly suffer. The only thing you can do about this is call the cable company and tell them what you think about it - or switch your providers.

You Need Better Cables

In most cases, provided your cables are short you don’t need expensive HDMI or DVI cabling for your system. You will get just as good a picture by using cheaper video cables. However, longer cables, especially cables near any source of interference, may corrupt your signal. This causes you to not have a picture at all, in most cases. Try hooking back up with a shorter cable; if that works, get the shielded, or change your setup.

You’re Playing Poorly-Recorded Discs

Not all movies are created the same. Sometimes the master that Blu-ray discs must use when they’re copied are not in the best condition, or the technician does not set up his parameters properly. This is another issue you can’t do anything about, but you can head it off by searching online before investing in any discs. New movies won’t have a problem, but the older library of stuff may have issues, and other people online will have found this and posted about it.

In addition, your regular television programs and DVDs may look fuzzier on your high-def TV than they did originally on your old set. That’s normal, and is due to the higher resolution having the net effect of magnifying irregularities - it’s like looking at printed paper through a magnifying glass. You see all the flaws. This is something you just have to live with.

My Friend’s Small LCD HDTVs Looks Better Than My Giant High-Def TV

Did you check the resolution? No matter the size of the screen, the resolution is what determines how clear your picture is. A large DLP TVs often has lower resolution than a smaller plasma TV, resulting in a lower quality picture. Always look at the resolution before making a decision.

If you’re one of the Flintstones, you may still be using an old-fashioned curved-screen television. It’s time to switch up to one of the new sharp high definition tv cheap hdtv, don’t you think?

All types of Flat Screen TVs - from LCD display televisions to plasma TVs and projector units, are superior to old screens in a variety of ways. They don’t lose definition when seen from the edges, making those least-desired seats in your living room perfectly acceptable. They also have significantly better resolution than old-style televisions. You may still be able to make out the pixels when you sit close, but because HDTV sets use digital technology instead of less-accurate analog, they have a much superior picture, either in still frames or motion. And they are designed to work well with all the latest technology, from blu-ray to HDTV.

Up until recently, flat-screen sets have been on the expensive side, and a lot of people who needed a new set were waiting until the prices came down a little. Well - it’s time. Small LCD TVs cost what an old-fashioned television would cost, if you could still find them, and even the large screens are often under a thousand dollars.

Before you buy, though, you need to understand a little bit about these new technologies.

LCD TVs use a liquid crystal display (LCD). Watches using this technology in monochrome have been around for decades, but only in the last ten years have researchers figured out how to create good-quality color liquid crystal that is reliable and long-lasting. An LCD TV has a nice thin appearance, and is basically a layer of liquid crystals sandwiched between transparent layers, with a backlight behind everything. The light shines through the liquid crystals, which have been polarized to show up in the different colors for your display - and there’s your television. LCD TVs, when kept dim, use very little electricity, making them great for a darkened TV room. And they are among the cheapest flat-screen televisions you can buy.

LCD TVs do have a couple of drawbacks: first, older models are subject to “ghosting”, where a dim image of a previously-displayed picture can be seen through the new picture; for this reason, it’s wiser to buy LCD TVs new. They may also not be the best choice for a fast-paced game, as they often have a lag time that can mess you up. Blacks aren’t always as sharp and dark as you might like, another reason to view in a darkened room. And if you mistreat it, you can wind up with “dead” pixels, where nothing will display because that segment of LCD has been destroyed. In most new LCD TVs, though, these problems are minimal or nonexistent.

Plasma TVs are also flat-screen televisions, but work very differently from LCD TVs and have a very different set of strengths and weaknesses. While you can lay an LCD TV on its back - carefully - without ruining it, a plasma television can be destroyed if it is laid flat. That’s because instead of liquid crystals, it uses an inert gas sandwiched between two pieces of glass to create its display. Seals more easily come loose when the plasma TV is laid flat, allowing the gas to escape right then or over time.

Provided you care for it well and mount it properly, your plasma TV will function well for years. Unlike LCD TVs, plasma TVs display blacks very well (one selling point) and most will also work great for fast-refreshing games. Plasma TVs are often advertised as having the most realistic, highest-resolution, best-contrast display of all televisions, and this is probably true in almost every situation. Drawbacks include the expense - plasma TVs are not economical to make in small sizes, so you’ll have to buy a large one - and the relative fragility of these televisions.

Both plasma and LCD TVs usually need good wall mounts. The last thing you want to do with your high-def TVs is install them, only to have them fall down a couple of weeks later! Quality wall mounts for HDTVs should include very good hardware, preferably made by the same manufacturer that produced the television, and excellent directions so you can easily put it up yourself. If you are at all worried that you will not install it right, it may be wise to have someone install it for you.

DLP TVs are the third major set of television displays in use today. These are also called rear-projection televisions, and while they are significantly cheaper than either LCD or plasma TVs, they also are larger and bulkier (though not as bulky as projection TVs were in the past) and have a somewhat less impressive display. Still, for most uses DLP TVs do fine, and because the light source in a DLP TV is usually replaceable by the consumer, they have a much, much longer lifespan.

Very similar to DLP TVs are projector units. These gadgets are often small enough to carry by hand, but can project a movie-screen-size picture if they have a high enough resolution. Similar in appearance to an old-fashioned slide projector, projector units are a great choice for a small area, for someone who needs a portable large television, or for someone who wants a television without having an obvious television.

Your Home Theater

Plasma TVs, LCD TVs, DLP TVs, and projector units are all high-def TVs, as long as they have the appropriate tuner. Once you have them set up, you need to think about other components of your home theater. After all, what’s a large-screen television if you have to sit in your old uncomfortable couch to watch it?

Your first thoughts should be for electronics to enhance your viewing experience: good surround-sound speakers for a great theater experience, and universal remote controls to sit in comfort as you control everything in your environment yourself.

Once you have your electronics in line, go for the last thing on your list: theatre furniture. Your home experience, with comfortable chairs that don’t fold up when you stand up, can be superior to one at the local movie house. Look for spacious, durable seats that can handle spills as well as roomy cup holders and somewhere to put snacks, remotes, and anything else you habitually keep close while you’re watching your favorite flicks.
