tvs plasmas or lcd questions?

Q. hello friends I'm saving some money to buy tv. but I'm not sure
which I should
buy
if you say plasma tell me way thanks

A. TV size matters. Read enough consumer and guru HDTV guides and you'll see that for most high end tech specs you want to break 40", and more so 50". In sets of 37" or smaller, you just need a basic TV (from a good brand, but just the basic spec sheet). You just don't notice the advantages of the better tech specs in those sized sets. So you don't get bang for your dollar then. If you get a smaller set with a high end feature, hey it won't hurt you at all, its just not worth the $.

The high end tech specs I'm talking about are 1080p (vs 720p), 120Hz/240Hz (vs 60Hz), LED LCD (vs CCFL LCD), and Plasma (vs LCD, either type). So if you break 50" a Plasma of 1080p is the way to go for sure quality wise. If you're doing 37" or less then look a CCFL LCD of 720p and 60Hz. In the 40"-46" range its a bit of a grey area. There are people who will argue for going into better features there and those that will argue against.

LCDs are inherently flawed in motion playback. They suffer from motion blur (ghost trails). This is compensated for with 120Hz and 240Hz sets. The feature helps the issue a lot, but it is not 100%. And you pay a huge price premium for the option.

CCFL LCDs (the majority) produce muted colors, grey blacks, and have a so-so contrast. This is compensated for with the LED LCD. The LED backlight vastly improves all of those aspects of image quality (but doesn't impact motion playback). LED LCD though still isn't quite Plasma levels. And you pay an even bigger price premium for this upgraded feature.

Plasma is inherently near instantaneous in its response time. This means it plays back motion flawlessly (just like a CRT or DLP would). And it does so right out of the box. You're not paying extra for this, its inherent to the technology. If you see stuff like 480Hz or 600Hz sub-field drive, this is something else, its not the refresh rate like of LCDs. Its actually more marketing than anything else. The two technologies are just very different.

Plasma will deliver vivid colors, true blacks, and deep contrast. Again it will do so right out of the box. You are not going to be paying extra for this. So it inherently delivers a stronger image quality.

Plasma really only suffers from myths and misconceptions. In the early days of the technology it suffered from burn-in, short life spans, a high price tag, and high levels of energy consumption. But that was decades ago, and all of those problems have long since been corrected. Modern Plasmas don't suffer from burn-in. The better brands even offer extra anti-image retention features, beyond the advancements in the technology. There are now sets that last from 60,000 - 100,000 hours (which is equal to or better than any LCD). The prices are actually a lot cheaper than comparable LCDs, because a comparable LCD would have to be 120Hz/240Hz and LED based. And you can buy energy star certified sets for Plasma now, so no more power issues.

If you go Plasma, look to Panasonic Viera first and foremost. With Pioneer getting out of the game, Panasonic is the leader in Plasma now. And their prices are really solid (and affordable). If that just isn't for you, then you can settle with either Samsung or LG Plasmas then.

If you go LCD in 37" or smaller, I actually kind of like Panasonic again. I prefer their color and black quality over other brands. They are known as a Plasma company for sure, but they make great smaller sized LCDs too. If that isn't for you, or you do want a bigger LCD, then look to Samsung and Sony first and foremost. They are the going to give you the best image quality. You can also through in Sharp Aquos, LG, and Toshiba in any size LCD consideration. All those 3 brands have respectable models.


Whats the difference between dynex 32"(dx-lcd32) and dynex 37"(dx-lcd37) lcd hdtv?
Q. I'm looking at the specs at BestBuy.com and I cannot find the Response time for the 37" Dynex. On the 32" it has a 8ms response time ample for gaming. I bought the 37 and it lags a bit with some of the games. And i was wondering if it had an 8ms response time too. It doesn't list it in the manual, on the dynex website or anywhere. Bottom line, What is the refresh rate for a dynex 37" lcd hdtv? (dx-lcd37)

A. 8ms is usually the minimum. dynex is a low quality hdtv, and although the 32" and 37" have different size panels the interio electronics are most likely very similiar ( it cheaper to use the same parts ) so i dont see a reason that dynex to change specs between sizes. so my educated guess would be it is 8ms. just so you know lcds as a whole have had problems with lag. especially with games. some dont show any lag at all , my 32" toshiba shows no lag. most of the higher quality name brands like panasonic, sharp toshiba sony samsung, do a better job at lag and have a better response time. but youpay for the quality. you get what you pay for in hdtvs. so in other words i see noreason it would not be 8ms. but that doesnt mean it wont lag. good luck
