We run down the pros and cons of LCD and plasma HDTVs. Which one is right for you?
HDTV - LCD Vs Plasma DisplaysBy [http://ezinearticles.com/?expert=Mike_Okada]Mike OkadaWhen the time comes to buy an HDTV, the first question that often comes up is: LCD or Plasma? Those are the two major types of HDTVs that are popular today. Each has its own set of advantages and disadvantages. We'll help to clear the air and assist you in making a well-informed purchasing decision.Inside of a plasma TV, lots of tiny gas particles are precisely charged with electricity in order to create a picture. In LCDs, a sandwich of liquid crystals combined with backlighting are used to create the picture.Because of this difference in backlighting, plasmas can do a slightly better job of displaying black levels when compared to LCDs. More precisely, this is due to the fact that the backlighting on LCDs is always on, so there's a chance for some light to leak out during dark scenes.This might also mean that you'll get higher contrast and detail from plasmas when judging those dark scenes in movies and TV shows. Experts also say that plasmas have better color saturation thanks to the lack of light leakage found in LCDs.Plasmas also have slightly better viewing angles when compared to LCD. Now LCDs have started to catch up to the plasmas but plasma still holds a slight edge. Typically, when viewing an LCD from more extreme angles, there will be some degree of color and/or brightness shift.Plasma fans will also say that image blur is more of a problem with LCDs. But with newer technology like 120Hz refresh rate screens, the difference is negligible.Price wise, LCDs are about the same or in some cases, cheaper than plasmas. Historically, plasmas have been available in larger sizes although there are super expensive special model LCDs that can match the size of some of the larger plasmas.In terms of image resolution, LCD has the edge. Inch for inch, LCDs tend to have higher native resolution when compared to their plasma cousins. This means that there's more pixels packed in the same size screen which means better image detail.LCDs are lighter and use much less electricity than plasmas. LCDs have a tendency to have longer lifespan than plasmas. In some cases as much as 30,000 hours longer than plasmas.Burn-in can be an issue with plasmas. Again, technology has come to the rescue so it's less of an issue now. But even in cases of burn-in, if you give the plasma a few days, there's a decent chance for the burned-in image to go away.For larger TVs (50+ inches) plasmas offers the most value with its slightly better image quality. For smaller TVs (42 inches and less) LCD is the better deal. On the bright side, if you're willing to wait, chances are good you'll get a better LCD set thanks to continuous rapid developments in LCD technology.In the end, the best way to buy a good TV is go down to the show room and look at some of these models for yourself. Or better yet, go to high end home theater shop or your friends house. Chances are much better that the TV will be in a more natural environment where you can fairly judge the image qualities of the TV in question.Trust me, you don't want to look at a HDTV in an overly bright showroom environment with all kinds of brightly lit eye candy flashing on and off in the immediate vicinity.Mike Okada contributes to [http://www.hereviews.com]Home Entertainment Reviews This site specializes in reviewing all things related to [http://www.hereviews.com]home entertainment equipmentArticle Source: http://EzineArticles.com/?expert=Mike_Okada http://EzineArticles.com/?HDTV---LCD-Vs-Plasma-Displays&id=1557420

You may know that 720p and 1080i are both HDTV standards. But what do they mean, and which one is best? We reveal all in this article.
720p Vs 1080i HDTVBy [http://ezinearticles.com/?expert=Kenny_Hemphill]Kenny HemphillIs 720p vs 1080i worth being concerned about? Yes and no. If you're a consumer looking for a new TV, you can happily ignore the 720p vs 1080i debate because every TV which is described as HDTV or HDTV Ready is required to support both formats.NOTE: You should be aware though that lots of TVs which support 1080i have fewer than 1080 lines and so scale the 1080 signal down. That's not a huge issue as even scaled down 1080i is far ahead of a regular NTSC signal. It is worth bearing in mind that more expensive HDTVs tend to have better scalers than cheaper ones, and this may be an issue.However, for broadcasters it's a live issue. Should they broadcast 1080 lines of interlaced video or 720 lines of progressive scan? They could just broadcast two signals, one in each format, but that would use up a huge chunk of bandwidth and be hugely expensive for very little gain.To answer the question, it's important to understand the difference between 720p vs 1080i. A 720p signal is made up of 720 horizontal lines. Each frame is displayed in its entirety on-screen for 1/30th of a second. This is know as progressive scan (hence the 'p')The quality is like watching 30 photographic images a second on TV. A 1080i signal comprises 1080 horizontal lines but all the lines are not displayed on-screen simultaneously. Instead, they are interlaced (hence the 'i'), ie every other lines is displayed for 1/60th of a second and then the alternate lines are displayed for 1/60th of a second. So, the frame rate is still 30 frames per second, but each frame is split into two fields, which your brain then puts together subconsciously.Most of the time interlacing works fine, but for fast moving images, such as sports like baseball and hockey it can cause problems which manifest themselves as a 'stepping' effect on-screen. Progressive scan signals don't have this problem and so are better suited to sports.ESPN puts it like this: 'Progressive scan technology produces better images for the fast moving orientation of sports television. Simply put, with 104 mph fastballs in baseball and 120 mph shots on goal in hockey, the line-by-line basis of progressive scan technology better captures the inherent fast action of sports. For ESPN, progressive scan technology makes perfect sense.'Bottom line? For us, as consumers 720p vs 1080i is not a debate worth worrying about, so you can relax and focus on all the other criteria on your list when you buy your next HDTV.Kenny Hemphill is the editor and publisher of [http://www.the-hdtv-tuner.com]The HDTV Tuner - a guide to the kit, the technology and the programming on HDTV.Article Source: http://EzineArticles.com/?expert=Kenny_Hemphill http://EzineArticles.com/?720p-Vs-1080i-HDTV&id=91443
