What is the difference between a plasma and LCD TV?

Q. What is the difference between a plasma and LCD TV? I see advertized on their website, a Vizio 42 inch plasma TV, for $650, including free shipping. Someone told me the reason why LCD is preferable to plasma, but I forgot what it was.

A. TV Size

TV size matters first and foremost. If you look through various consumer and guru guides you will see that its essentially a consensus that you need not worry about high end features unless you are going to break 40" and more so 50". The reason being is that you can not see the advantages of those features in smaller sets. But being that you're looking at 42", an advanced feature/option, like Plasma, makes sense.

LCD

LCDs inherently suffer problems with motion playback. They suffer from motion blur (ghost trails). This is compensated for with the 120Hz/240Hz refresh rates. This feature helps out a lot, but is not 100%. And you are expected to pay a price premium for this add-on.

CCFL LCDs have muted colors, grey blacks, and so-so contrast. This is compensated for with the modern LED LCD. The LED backlight provides a massive jump in quality in regard to those 3 things. It brings it to a near Plasma/CRT/DLP level.

But in smaller sets, LCDs are the go to choice. So for the time being they will certainly still fill an important need there. And there also offer a certain sense of familiarity for many, as LCD computer monitors have been the norm for so long now.

Plasma
( http://en.wikipedia.org/wiki/Plasma_display )

Plasmas are inherently near instantaneous in their refresh rate. They are flawless in motion playback. While you might see some tagged with 480Hz or 600Hz sub-field motion drives, this is not a refresh rate. Its more so marketing to trick consumers (because of LCD's refresh rates). But in reality the technology just works quite differently (its more like your old CRT/tube set).

Plasmas inherently deliver vivid color, true blacks, and deep contrast. They do this right out of the box. They are a better overall image. And so you get a better image and perfect motion playback without having to pay anything extra.

Plasmas were not always this good a choice though, they have improved greatly over the years. But because of those past problems they do currently suffer from many myths and misconceptions. The main ones being that they suffer from burn-in, they are more expensive, they have shorter life spans, and they are energy hogs.

Modern Plasmas do not suffer from burn-in. After they are conditioned, you would have to actually work hard to accomplish a burn-in. To condition a new set all you need to do is keep the brightness and contrast turned way down for the first 100-200 hours of use. After that optimize and enjoy.

Plasmas are not more expensive than LCD rivals anymore. Any especially with LCDs needing high end features like 120Hz and LED backlights to compete. Those features often make LCD far more expensive to buy.

Plasmas do not have shorter life spans. The reputable brands will deliver models that are rated to 60,000 - 100,000 hours. That basically means that in 10 years time, at 8 hours a day, 365 days a year, you would only really see at most about a 10% loss in brightness. So the set is likely well useable for beyond 10 years.

Current Plasma models are now energy star certified. This means no more being power hogs against LCDs. They can match LCDs in this regard. But every model is different. There are some LCDs that still perform better, and there are some LCDs that perform much worse. It changes ever year as new models come out.

Brands

Though for Plasma I would recommend looking at Panasonic or Samsung before Vizio. Look at Best Buy right now for some sales on 42" Plasma TVs from those better brands. Vizio doesn't really have the reputation of being an elite Plasma TV manufacturer.

The Samsung PN42B450B1D is on sale right now for only $680. The Panasonic TC-P42X1 is on sale for $700. That's two 42" Plasmas from top tier manufacturers, still within the same price range.


Does the lcd Acer X203Wbd come with a dvi cable?
Q. Hello.....I am going to be buying my first lcd monitor and have narrowed my decision to the Acer X203Wbd. If you own it what do you think about it? Does it come with a DVI cable? Please tell me your exprience with it good and bad. Also, what would you recommend to protect the screen. It is an good investment and my first LCD, so of coarse i'm going to protect the screen =) Thank you

A. Sorry to say that my (subjective) opinion is Acer, AOC & Westinghouse LCDs are the lower end of the larger LCD monitors and sell at retail stores from would you believe like $100 to $160 and whether the LCD comes with DVI cable or not shouldn't matter too much in your decision bec price of DVI cable is really small and in fact Did you also check if the video card on your PC has DVI port bec older or less expensive computers do not DVI port and you might have to buy new video card...

I have the superexpensive $500 to $600 24" Dell Ultrasharp LCD sitting on my desk at work that has the adjustable sturdy stand and USBs. Our Agency tends to overkill bec we soon will all workers will be also getting new Dell Latitude Notebook PCs with docking stations as well.

At home I went out & bought a 22" Dell LCD monitor for my new Dell XPS Studio XMT 435 that 6GB DDR3 memory and a 512MB ATI video card and surprisingly the pic is even clearer and better than at my pic at work...implying that a good LCD monitor also needs a good video card. Also I would not worry too much about protecting screen bec I also did same TLC on an expensive Dell Notebook PC with high gloss screen but protective screen looked terrible that I sent back for refund. On the other hand, our Agency bought $150 3M glare protectors for each of the 24" Dell Ultrasharp LCDs and personally I think was a waste/overkill...bec simple water and microfiber cloth keeps good LCD monitor sparkling like new condition...

Bottomline, what I like about the Dell LCD monitors is their sturdier stand but we also have other Dell/Sony desktop PCs at home and recently bought a highly rated 22" LG Flatron LCD on sale at Best Buy from $289 to $189 plus tax. FYI there are so many LCD monitors on the market and the prices for 22" LCD monitors are very competitive that soon it will be like 1080p HDTVs <= we now have 2 and personally I wouldn't recommend going overboard bec technology is rapidly coming out with new models.

Hope the Above Info Helps!
