do all HDTVs have the same amount of picture quality?


im saving up to buy a HDTV for my room so i can enjoy my ps3 with good graphics. i dont understand some stuff when i read the TVs description when it says stuff like LCD and LED and 1080p and 720p, is the higher the better? also i heard LED is better than LCD.
what im really asking is, what should i look for when im trying to buy a HDTV to get the best picture quality. thank you :D

LED is better then LCD and the difference between 1080 and 720 is the graphics, the bigger # the better the graphics will be so I would go with 1080. I think a VHS is 470.

What is the best LED HDTV?


LED TV Technology is a relatively new feature in the world of HD Television. They are thinner and have a better definition display than typical LCD TVs that use fluorescent lamps as a light source. The hype surrounding this new technology has resulted in Samsung selling approx one million LED TVs worldwide in 6 months.
However LED televisions are not technically that different from conventional the LCD TVs that have been with us for the last few years. In fact the term âLED TVâ has been questioned as an LED TV is just a liquid-crystal display TV that uses light-emitting diodes to light the screen. Britainâs Advertising Standards Authority recently had problems with some marketing of LED TVs. The ASA said that the term LED TV is merely a variation of LCD TV and was misleading. As a result clarification relating to the use of the LEDs as the light source is now used when advertising LED Televisions.
Other television manufacturers have also come out and said that rather than LED TV it should be called an âLED-lit LCD TVâ as this more accurately describes the use of LED technology used in these TV sets.
Up to now Sony, Samsung, Philips, JVC and LG have LED TVs on the market. The plus points with these new sets are that they have better picture quality, are thinner and are more eco-friendly mainly due to reduced energy consumption. On the negative side, as is to be expected with any new technology their price tag is still a bit on the hefty side.

The LED lighting in these new set is employed in one of two ways either as edge-lit LED TV or backlit LED TV. Edge-lit televisions as you have probably guessed have the LED lighting situated around the edge of the screen. Without the larger fluorescent lighting previously used at the back of the TV, LED models have been reduced in thickness with Sony producing an LED display less than 1cm thick and Samsungs sets measuring in at 3cm thick.

LED TV technology has made great advances with energy efficiency. Compared to their equivalent conventional LCD Television models, LED HDTVs use typically 40% less energy. And when compared to plasma TVs they can be 50% more efficient. The improved energy efficiency is due to the fact that LEDs require less power to illuminate the screen than fluorescent lights used in older LCD screens.

SONY BRAVIA XBR8 LCD flat panel HDTV. In addition to Full HD 1080p, this XBR-8 Series TV features TRILUMINOS RGB Dynamic LED backlight which produces breathtaking images with enhanced color purity that result in deep blacks and bright whites with startling depth and exceptional shadow detail. You'll also see the difference with Motionflow 120Hz PRO technology which enhances motion and delivers a smoother and clearer picture. Your 1080p HD images will look more breathtaking than ever thanks to the BRAVIA Engine 2 PRO fully digital video processor. This XBR-8 Series TV has DMex functionality which lets you expand the capabilities of your HDTV by adding optional BRAVIA Link modules (sold separately), plus it comes with plenty of connectivity options to connect your video sources.

TRILUMINOS RGB Dynamic LED Backlight
TRILUMINOS RGB LED backlight technology aligns individual clusters of red, green, and blue LEDs to produce a significantly higher purity of primary colors than single white LED backlights, resulting in more accurate color reproduction. This clustered arrangement also allows the XBR8 to adjust the brightness of the backlight in units of small blocks, so it can display deep blacks in one portion of the screen and bright whites in another, producing images with enhanced depth, three-dimensionality and exceptionally accurate shadow detail.
Further, unlike conventional full-screen luminance control, the BRAVIA suppresses unneeded backlighting and, therefore, consumes less power than the conventional LED-backlit models. And, because it uses LEDs rather than the fluorescent tubes found in many HDTVs, Dynamic LED backlighting also promises exceptionally long life.
