best led tv hz image

I am thinking whether to spend $200 more on an Samsung LED 120 Hz TV vs Samsung LCD 120 Hz Tv. Do you think the picture quality of an LED TV will be better when watching HD Channels on Dish Network?
Answer
The claim that "LED gives better picture quality than LCD" is one of the most common myths in this business.
In the first place, an "LED" set is nothing more than an LCD set with a newer type of backlighting. They both have the same LCD display.
In the second place, lab tests and owner reviews demonstrate that the important factor in picture quality is the specific model of a set, not its brand or whether it uses LED backlighting. While LED technology does provide advantages, there definitely are conventional LCD sets with better picture quality than certain low-rated "LED" sets. You need to carefully look at test results and user reviews in order to make a valid decision.
So the bottom line for you, in my opinion, is no--the picture quality difference, if any, won't justify another $200, unless the specs, reviews, etc. of the cheaper set suggest otherwise.

Are LED Screen TVs really more energy efficient?
RobReads
I heard in a news report a while back that LED TV screens would use a lot less energy that any TV made so far. Now I see them on the market, but the ads don't stress this. Are they significantly more energy efficient?
Answer
Generally, if other things were comparable, an LED TV is more efficient than an LCD, and they are both better than CRT tvs. There is no true "LED" tv yet - they are LCD tvs that use an LED backlight. Still they gain a little efficiency.
The problem in comparison happens because there are so many variables.
Each generation of TV has a revised set of power settings - from basic brightness to "ambient light settings" and the power drawn when the device is off or in "standby". Even if we compare two similar 40" flat screen televisions, if I have mine set for maximum brightness and crank up the color levels, my TV will use 15-30% more energy than one that is tuned for efficiency.
If my TV has twice as many pixels, or I have a higher refresh rate.. then I use more energy again.
Since the newer TVs are the only ones using the LED technology, these same new TVs are likely to be "hi-def" (more pixels 720p, 1080p etc.. ), and higher refresh rates ( 60hz. 120 hz, etc..) - the comparisons are not true "apples-to-apples" comparisons.
If you could find a group of machines that had all the other features the same.. or at least very close.. the LED backlight vs the LCD backlight should save about 10% (per IEA.org link).
You might save almost that much just by unplugging the set when not in use.
Right now, only the small OLED screens we see on cell phones are true LED.
Unless you spend real $$$, true LED tv won't be available for several years yet.
