Modern LCD TV sets have a staggering array of features despite the recent emergence of HDTV related features taking center stage. While HDTV related features can make or break an LCD TV, they do not stand alone: the venerable PIP, reverse 3:2 pulldown, and even highly technical aspects of the underlying technology such as 3D Y/C digital comb filters all work together to present the best possible viewing experience.
PIP, or Picture In Picture, technology has been around since the dawn of big screen TVs. PIPs are areas of the screen designated to display another video feed such as a PS3, home security system, or even just another channel than that which is being watched on the rest of the LCD TV screen at the moment. In short, the more PIP boxes an LCD TC generate, the easier life can be for families/offices with conflicting interests: Watching one channel, while surfing other channels, while the children play the latest video games, while the front door security camera lets one watch for visitors can all be possible simultaneously.
A reverse 3:2 pulldown is necessary for anyone planning on using older 24 frame per second technology with 30 frame per second LCD TVs. Without modern reverse 3:2 pulldown technology, anything that was not designed to present at 30 frames per second would quickly become distorted or appear to jump around the screen of an LCD TV. If one has ever watched a new broadcast where older CRT monitors or televisions are visible in the background with the have witnessed that strange distortion of what should be a very clear picture. This is caused by a disparity between the video capture speed of the camera and that of the display. While it is not possible to correct problems like this that are actually part of the video, it is possible for this effect to be removed or at least severely mitigated on LCD TVs by ensuring that everything runs at a smooth and even 30 frames per second.
Advanced visual presentation features such as 3D Y/C digital comb filters separate different colors into different data streams. The separation results in easier and quicker analysis of each of the scan lines prior to being displayed, which effectively translates to amazing picture output. An advanced color separation technology such as 3D Y/C digital comb filters also allows for individual colors to be corrected much easier. Not all display technologies are equal, and manufacturers sometimes need to tweak data bound for the LCD TV display in order to ensure proper presentation.
Of course, HDTV is the big buzz word in modern LCD TV lingo. Different resolutions such as 1080i, or 720p indicate not only the amount of pixels (colored dots) an LCD TV has, but also whether or not those pixels are updated one half at a time as is the case with interlaced (i) systems or all at once as in the case with progressive scan (p) models.
Last but not least, do not forget the connectors. The best LCD TV technology is nothing without high quality digital input to display.
