What is the difference between Plasma and Lcd tv? Which has the clearer, crisp picture? ?

Q. I am totally confused! I thought that the LCD was supposed to be the clearer one but my son bought a plasma at the same time that I bought a LCD and his picture is much more clear than mine(he has subscribed to HD cable I've yet to sign up) Is it the HD cable that makes the difference? I would really like to know the difference between the two sets.

A. Plasma vs LCD

The ADVANTAGES of Plasma over LCD are:

1. Larger screen size availability.

2. Better contrast ratio and ability to render deeper blacks.

3. Better color accuracy and saturation.

4. Better motion tracking (little or no motion lag in fast moving images).

The DISADVANTAGES of Plasma vs LCD include:

1. Plasma TVs are more susceptible to burn-in of static images.

2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images.

3. Does not perform as well at higher altitudes.

4. Shorter display life span - this used to be the case. Early Plasmas had 30,000 hours or 8 hrs of viewing a day for 9 years, which was less than LCD. However, screen life span has now improved and 60,000 hour life span rating are now common, with some sets rated as high as 100,000 hours, due to technology improvements.

LCD television ADVANTAGES over Plasma include:

1. No burn-in of static images.

2. Cooler running temperature.

3. No high altitude use issues.

4. Increased image brightness over Plasma.

5. Lighter weight (when comparing same screen sizes) than Plasma counterparts.

6. Longer display life used to be a factor, but now LCD and Plasma sets both have at least 60,000 hour or higher lifespans.

DISADVANTAGES of LCD vs Plasma televisions include:

1. Lower contrast ratio, not as good rendering deep blacks.

2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts) - However, this is improving with the recent implementation of 120Hz screen refresh rates in higher-end LCD sets.

3. Not as common in large screen sizes above 42-inches as Plasma. However, the number is growing fast, with 46 and 47-inch screen sizes becoming more common, and some LCD sets having a screen size as large as 65-inches now available to the general public.

4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you.

5. LCD televisions are typically more expensive than equivalent-sized Plasma televisions (although this is changing), especially when comparing EDTV Plasmas to HDTV-LCD Televisions.


What is the best and cheapest Big Screen HDTV available?
Q. I'm looking for a 46" or 50" big screen TV. My budget is around $900 - $1100. I'm not to concerned with the type of TV, wether it's LCD, Plasma or Projection. Although, this new TVs main purpose is for gaming, so it must have HDMI and at least 720p. I'm also worried about latency as I've read that some newer televisions can be a little slow to display the image due to the image processing that takes place. Does anyone have any good recomendations as to a tv brand or type that fills all these criteria and is within my budget? I'm not opposed to purchasing online although I still want to stay within my budget after tax and shipping fees.

A. I do in fact have a recomendation and it's one shared by most experts in the audio/visual field. At this point in time the Hitachi f59 series is the absolute best bang for the buck available on the market, bar none. LCD? Plasma? DLP? Nope, it's got every set below $3000 covered hands down in every relevant category, be it picture quality, gaming performance or maintenance cost. The fact is that CRT is still the benchmark all others are judged by and at this point in time a High Def rear projection set such as the Hitachi offers the savvy buyer all the goodies without the hassles.

The F59 series is available in 51, 57 and 65 inch screen sizes, and as to price, well lets just say that on a good sale day you can pick up the 65 for between $1000-$1200 and the 57 for $999. Personally, I'd wait for the annual 'After the Super Bowl' sales as most retailers really offer some blowout pricing at this time, many close to those of 'Black Friday'. It was 'Black Friday' which put the 51 inch version on my doorstep at $699 shipped and I couldn't be happier with this set, heck I'd have paid full price and still considered it a steal. Yes, it really IS that good! But don't just take my word for it, take a look for youself at some of the factors which lead me to this purchase.

For instance lets look at the bulbs, or should I say lack of. ALL of the others technologies require an arc lamp bulb to provide the light source and it does a wonderful job...for about two years. 18-24 months is the average life expectancy of these bulbs under normal viewing conditions, then its time for replacement at a cost of $200. Average that out over the ten plus years you'll watch your typical CRT rear projection set like the Hitachi with ZERO bulbs and you'll see just what the latest 'High Tech' is really worth.

As you're a gamer this is the best choice once again due to a few things, the foremost being response time. CRT doesn't have to measure pixel response in milliseconds because there are none, thus instant and true image representaion is there 24/7/365. This is critical when playing first person shooters such as Halo on Xbox Live as the lag associated with the other technologies allows the slightest bit of lag. Sure, a 10ms lag doesn't seem like much but it is the difference in that hitting and missing those vital split second shots, the difference between tea bagging an downed opponent or cursing yourself blue over why your 'dead on' head shot failed to take out the bad guy. Of course the fact you require an HDMI port tells me you're of the PS3 persuasion but this set does indeed have and support HDMI so that's another base covered. Oh, and screen 'Burn In' isn't really an issue either anymore so than any other set, in fact less if proper caution such as not leaving ANYTHING paused for extended periods of time are taken.

Now as far as movie watching goes I certainly hope you have access to a lot of DVDs because viewing them on this set is more addictive than heroin or internet porn. My personal collection grows by the week now, even movies I've seen a million times gain new life on this set. And as for cable, well I have digital cable and see NO reason to upgrade to HD because the Standard def stations would remain the same and the combo of digital and this TV make you swear you were watching true High Def when tuned to any of the Discovery Network channels.

I'll not even go into the realm of picture quality, suffice to say 1080i with the true blacks and true color representation only CRT can deliver is still king of the hill despite every attempt to knock it off. So go ahead and pull the trigger on one of these bad boys, I promise, you'll not be dissapointed in any way, shape or form. Good luck and happy viewing
