TV experts, I need your help!!!
I'm starting to shop around for a new living room TV for my wife and I. We currently have a huge 32in CRT looking thing. We're interested in a 42-47" flat screen, either LCD or plasma. Price range $650-800.
Researching these is making my head spin. There are so many TV's around. This is going to be primarily used for digital cable TV. HD isn't a huge factor to me. Also sound quality is important.
Anyone have a recommendations, feedback, advice? All appreciated.

In that price range given that you don't care as much about HD you will get the best picture out of a 720p plasma. Realistically, as far as sound quality goes, you are best off buying a small home theater setup and using that. No flat panel speakers are all that great. Not terrible, but not great. Walmart has a 50" plasma setup with home theater for $750 http://www.walmart.com/ip/SANYO-50-C...-HDMI/14957802

the 42 might have been $600 in the LED. I have the 47 LED in my bedroom, it is a quite nice picture.

SO many TV's, so many reviews. I'm starting to think plasma my be the best bet, for what I'm looking for.

Basically sams club or Costco have the best non-online prices and good return policy . It's often hard to neat them even online.

Here's my opinion and I am a bit of a TV/electronics junkie. PLASMA. Most LED's/LCD's operate at a refreshe rate of 120hz. Some out there now are 240hz. the "cheap black friday deals" are 60hz. This means, how fast the screen deals with motion essentially. If you like sports, get the highest refresh rate you can. Which, just happens to be PLASMA. Almost all plasmas work at 600hz....there are no LED/LCD's doing that now, and certainly if they were, they would not be in that price range you mentioned.
Now - 720p, 1080i, 1080p -- unless you are going with a Blu Ray player, 720p is fine. 1080i is on all TV's most of the time anyway.
Lastly - CONTRAST RATIO -- pay close attention to this. Cheap LCD's/LED's will have less than 100,000 to 1 ratios....I bought a "Deal" and it was 4,000:1 ratio and it SUCKED. Plasmas have generally, 1,000,000:1 ratio on the low end.
Bottom Line - Go Plasma, get the biggest bang for your buck. Selling point of LCD is it's a lighter TV vs. Plasma which is quite heavy, proportionately speaking. And thus why LCD's took over - - much much cheaper to ship/produce in 3rd world countries.
Off my soapbox.

I've got a 50" Hitachi plasma (720p / 1080i) that I've had for 2 years and it's been great. Bought it for $1,000 back then and you can find the same thing for virtually half the price now.
As has been stated, unless you're gonna be rocking Blu-Ray, there's no need for 1080p, since most broadcasts are compressed, still. Sports look amazing in 720p, especially compared to standard definition.

One question, though: did they standardize contrast ratios? From what I'd read (granted, it hasn't been for at least a year if not longer), the contrast ratio was determined by the company and therefore 1,000,000:1 for one company might actually be equal to 10,000:1 for another company. Any insight regarding that?
12-06-2010, 11:39 PM
That's the first I have heard about contrast ratios being standardized. I can say this...I bought a 26" Vizio with 4,000:1 contrast ratio and it just sucks (LCD). I bought a vizio 32"
(also LCD) with 100,000:1 contrast ratio and it's pretty decent...much better than the small one....so go figure, typically a smaller screen will look sharper if all things are equal....My plasma I have in my den is 1080p and it's great with Blu Ray. All tvs that are HD have 1080i. But that always brings up the point of the source programming if watching on TV. Was it recorded in 1080i? Is it being broadcast in 1080i? etc. etc. Like a new Blu Ray of gone with the wind is not going to be the same as watching Avatar on Blu Ray....get my drift!

Just to add, although I do recommend a plasma, both their refresh ratings as well as contrast ratings are a joke. Outside of potentially video game systems or 3d bluray systems NOTHING comes in at higher than 60hz. The reason why early LCD panels were blurry in fast action wasn't refresh rate, but cycle time for a pixel to go from fully off to fully on to fully off again. Early sets took as long as 10-12 ms for a pixel to flip fully, once they were below around 8ms the blurriness started going away, and below 4ms its nonexistant. Still, a plasma gives better blacks, better color saturation and accuracy and overall better performance than anything but the high end LED LCDs (which cost far more).

It really isn't that big of a deal because after you focus on the images for so long, the lights sort of blend into the background but as soon as a commercial comes on, you have to refocus on the images again..its one of those mind/mental situations.
Strangely, where the room lights reflect off the plasma screen is to the left side, and for some reason my left eye waters when I watch the plasma but it doesn't when I watch any of the LCDs. < I know that statement is one of those wtf, LOL, but any info may help!

Temporal/Timing Performance: Contrary to spatial performance, temporal performance is a feature where smaller is better. Specifically, the range is the pixel response time of an LCD, or how quickly you can change a sub-pixel’s brightness from one level to another. For LCD monitors, this is measured in btb (black to black) or gtg (gray to gray). These different types of measurements make comparison difficult. Further, this number is almost never published in sales advertising.
Refresh rate or the temporal resolution of an LCD is the number of times per second in which the display draws the data it is being given. Since activated LCD pixels do not flash on/off between frames, LCD monitors exhibit no refresh-induced flicker, no matter how low the refresh. rate. High-end LCD televisions now feature up to 240 Hz refresh rate, which requires advanced digital processing to insert additional interpolated frames between the real images to smooth the image motion. However, such high refresh rates may not be actually supported by pixel response times and the result can be visual artifacts that distort the image in unpleasant ways.

So I think these are my choices.
The Samsung is entry level, but a great price.
Samsung: Samsung - 42" Class / 720p / 600Hz / Plasma HDTV - PN42C450B1D
Sony: Sony - BRAVIA 46" Class / 1080p / 60Hz / LCD HDTV - KDL46EX400
Panny: Panasonic - VIERA 42" Class / 1080p / 600Hz / Plasma HDTV - TC-P42U2

I have the Samsung LN46A530 - 46" 1080p and it is AWESOME! I love it! The SRS audio (surround sound from the tv) is really good (I was quite skeptical), and the video quality is spectacular. I've had mine since November 2008, and never once regretted it! And the difference between 720 and 1080p now-a-days really isn't that much anymore (for LCD anyways), so I would really go for 1080p. I used to have a 32" Samsung CRT 1080i, and I can see a big difference!

As an avid HDTV junkie, I have a few things to add. I will focus the majority of my points on LCDs, as that seems to be the current trajectory of the conversation.
Motion blur/artifacts/lag or whatever nomenclature one chooses to employ is an inherent problem of LCD-based technologies, including LED. This 'lagging' is the confluence between two variables that Easy details above: the response and refresh rates of an LCD television set. Before I go on, it may be useful to translate Easy's helpful paragraph into layman's terms.
On the one hand, response rate (RR) simply indicates the amount of time that an individual pixel takes to cycle to and from active and inactive states. RR has been measured in numerous different ways, with the two predominant units of measures being BTB (black-to-black) and GTG (gray-to-gray) - or in other words, the amount of time a pixel takes to go from black/gray to white and back again. While on the other hand, refresh rate simply indicates the amount of times per second the display draws the data from the source: the higher the refresh rate (measured in hertz [Hz]), the more times an identical frame can be displayed before the TV draws new data from the source.
As Easy indicates, early LCD sets often had slow response rates - relatively speaking, of course - that averaged out to 12 milliseconds (ms) or thereabouts. The longer the response time, the poorer the TV performs in reproducing moving images. This is more or less an intuitive concept. As your TV attempts to imitate motion by reproducing a sequence of still images, pixels in different areas of the screen need to be activated or deactivated: if a set's response time is slow, a pixel will retain a portion of the image, and this will create a "blurring effect."
The relationship between blurring and refresh rates occurs under a generally similar pretense. As your TV set draws new frames from the source at a rapid rate to create the illusion of a moving object, it abruptly shifts from one still image to another: if the set is refreshing at a slower rate, say, 60Hz, the moving image will appear to have a shadow or blur. (Which is, of course, simply the still image from the previous frame.) The higher the refresh rate, the more times per second data is drawn from the source, and the less obvious the reproduction of moving images becomes.
Now, choosing an LCD TV based on these specifications, as we can infer from Easy's blurb, is becoming more and more difficult. First, manufacturers tend to manipulate the response rate specification by altering the manner in which it's measured, or refuse to disclose the information altogether. This is a particularly constant practice for lower-tier manufacturers, and to a lesser extent, from top-tier manufacturers releasing "entry-models."
Second, the once-reliable refresh rate specification is becoming quite dubious itself. While manufacturers may list up to 120 or 240Hz, this may not necessarily reflect the true refresh rate of the set. While an actual 120 or 240Hz set has doubled or quadrupled the actual activation rate of the pixels, some manufacturers use techniques such as interpolation or LED-backlight manipulation to reproduce a "120/240Hz effect." Unfortunately, because the measurement techniques for these specifications are easy to manipulate, these 'imposters' are still legally able to list the refresh rate at 120 or 240Hz, though the data may still be drawn only every 30th of a second (60Hz).
Third, and finally, a higher refresh rate on an LCD set may not necessarily translate into a higher performance. As almost any review or technology site will discuss, the higher refresh rate LCDs, while performing well with sports or other constant-movement programming, produce very nasty artifacts with still images. As the same still image is reproduced at quadruple the speed, objects in that scene which are not intended to move at all become unpleasantly sharp. This largely negates the purpose of 120/240Hz TV, as the majority of your content, I assume, will not be sports.
As a result of all this, choosing a lower-tier or 'entry-level' LCD is, in my opinion, generally a very poor idea. Response rates and refresh rates are not often accurately represented at best, and they are manipulated to sell lower-performing TVs at worst. While lower-tier plasma sets come associated with their own host of problems, motion blur and artifact production - one of the most annoying experiences when watching your set, believe me - are not one of them.
Out of your available options, I would go with the Panasonic U series. For an entry-level model, it performs reasonably well, and you will not need to deal with blurring issues. If you can, however, I would comb the internet for refurbished G10's (Panasonic TC-PXXG10), as they are last year's model and could be found at a reasonable price.
For reference, I have both LCDs and plasmas. I have two LCDs (an older rear-projection Wega, and 2009's Samsung LN40A650) and two plasmas (Panasonic TC-P46G10 and Panasonic TC-P54VT25 [3D]).

Don't forget the possible issue of refelctions when going with Plasma... darker rooms with less windows are ideal.

Ya, I do know from experience that many LCDs can get horrible glare as well. I think it's pretty much standard for any tv though.
