Well I feel I was misled by a lot of posts on the internet with Plasma vs LED LCD. Maybe the stereotypes were true with older LCDs but definitely not with new LED LCD TVs.
I'll give a run down about my viewing experiences. I've been into the Home Theater hobby for about 15 years and have fought to find a high performance CRT in the past. I did, I found a JVC 36" AV-36D302 TV. While it has a round TV tube, it's geometry "surprisingly" wasn't inferior to most 'flat' screen CRTs out there. It's price is was similar to what LED (w/dimming) LCD 47" TV cost today and was more expensive than most 50" Plasma TVs. I bought it back in 2000 so it was only 11 years old.
I really was nit picky on blacks, geometry, white output, contrast, and color. It took me a while before I found a CRT TV that I was happy with and that was that JVC.
After reading threads and articles on the internet, I was led to believe that Plasma TVs were the end all to all TVs.
Making comparisons in an HHGREGG store was really hard with their bright lights and poor setup. I really didn't see a difference in the Plasmas vs LED LCD in that condition except the Plasma TVs were darker.
Well I ended up buying a LG 50" 50PV450 Plasma expecting to be blown away. After setting it up in my home, I was not blown away with picture quality at all. I was blown away by the HD definition but everything else seemed to trail my JVC TV's performance EXCEPT Geometry, CRT analog noise, along with the higher resolution.
Then I started to see the Automatic Brightness Level control issue that has numerous complaint posts here. Never heard of it and never seen the posts until I went looking for a fix for my problem. Then I learned it was the ABL that was causing brightness strobing and flickering on most scenes that changed in brightness. It literally drove me nuts.
Also reflectiveness on these sets is really under exaggerated. It's very bad being worse than even my JVC CRT (which I expected it to be about the same). In brighter room with 2 lamps on at night or with the drapes open, darker scenes were unwatchable because of reflections. This was a major disappointment as well.
So it was going back I was set to go back to my CRT that was enjoyable to watch.
Then I decided to try LED LCD and go against all the negativeness I read about.
Anyhow, some LED LCD TV's blew away many Plasmas.
You can not judge a TV based on it's technology whether it's plasma or LCD. You have to judge the TV based in it as an individual set.
My new 47" LG 47LW5600 is so so much better than both the LG Plasma and the JVC CRT, it's remarkable!
Now there are issues with LED Edge Lit LCDs. There is flashlighting and clouding. These are caused by the LED shining out from the edges. Flashlighting is when LEDs must shine across black areas to create a bright area further out. It looks like a flashlight beam that is narrow then widens out, in an isolated stream of light. Clouding is created the same way but is more or less, blotches of brighter areas on a dark screen.
Now in my set, both are really limited if not alleviated with local dimming. This shuts off LEDs that are not needed so it can create blacker black areas and a better contrast ratio.
In my set, I have very minimal clouding at the edges, although some is still there. CRTs created a similar affect but through a completely different way. With CRTs, it was called blooming. That is really the only negative that I found in my set.
My LED LCD LG 47LW5600 has exceeded the previous LG 50PV450 in all picture quality areas. It's motion is no worse in my living room. At extreme's it can dim and wash out, but seriously, who would watch a set at that angle anyhow. We have our couch in front and love seat off to the side, and we can detect no dimming and no washing out of the colors. It's actually has a wider viewing angle than my older JVC CRT due to it's round CRT (Tube). The LG 47LW5600 also has a great anti-reflective screen. It doesn't destroy the picture quaity and make darker sceens unwatchable in brighter rooms as did the LG Plasma. The JVC CRT wasn't as reflective as the LG Plasma and while reflections were still distractions, it didn't make some screen difficult to see as did the LG Plasma.
So my LG LED LCD has been a better performer in the areas listed below:
Black areas as the LG Plasma didn't have the greatest black levels
Picture Noise (plasma has some dancing noise in the screen as did the CRT but to a much, MUCH less degree). This might be a byproduct of the Phosphor screen. However it is barely noticeable unless you were right up to the screen.
Brightness Fluctuation, strobing and flickering
The Plasma wins in one area with black level uniformity as there's no clouding or flashlighting with Plasma.
Color was about the same, I seen no differences to make me judge one over the other.
So there it is. The negatives of each technology as one technology's issues may be less bothersome to different people. While my wife has watched a poor TV with noise and herringbone lines for years without complaint, she's less picky. She saw the Plasma strobing and flickering but was not bothered by it. Obviously I was.
So with the negatives of each technology aside, pick the TV based on an individual performance output and not by the technology. I guess it's always been said not to stereotype.
BTW, once I had noticed the ABL issues on my LG Plasma, I also seen them on other Plasma TVs at Best Buy. There are threads and posts complaining about the ABL on LG, Samsung and Panasonic in forums here.
Another note: The LG LED LCD has a list price of $1699.99 while the LG Plasma 40PV450 had a list price of $899.99. I was fortunate and was able to get the 47LW5600 for only $100 more than the LG 50PV450.
While the LED LCD was almost 2X the cost, it offers a lot more features as more HDMI inputs, 3D, Smart TV (not netcast)that offers netcast plus applications and web browsing, Wifi enabled, and 4 pairs of 3D glasses.
The LG 47" 47LW5300 is more in line with pricing as the 50PV450 for a list of $200 more, but the 47LW5300 is 3D enabled and comes with a 3D Bluray player along with 4 pairs of glasses.
The 47LW5300 looses the 47LW5600's Smart TV function and netcast, 3D function, wifi enabled, the better ISP screen, bluray player and has a 4M contrast ratio opposed to the LW5600's 8M contrast Ratio along with the Magic Motion pointer mouse remote.
Just my observations with several TV. Others may find Plasma more pleasing but this is a "VS" thread.
