How to Appreciate Features of LCD TV

Liquid Crystal Display (LCD) TVs have become popular along with its plasma rivals. The LCD technology is fast providing the consumers with some amazing features.



Step1
Explore the progressive scan support that is provided by all LCD TVs. This feature provides a pleasing flat screen design and great visual quality.


Step2
Check out the compatibility for High Definition Television (HDTV). Many LCD TVs support this feature. The upgrade allows the users to have high quality of audio-visual advantage in their TV. LCD TVs also include several inputs, plug and play options making them versatile.


Step3
Find out the aspect ratio and video image conversion. Standard TVs have a 4:3 aspect ratio or 4 units wide and 3 units high. All LCD TVs with HDTV compatibility have a 16:9 aspect ratio. This means they are a little wider than standard TV proportions. The feature is worth appreciating, as it ensures that the stretch is least in the center where your eyes are focused and more at the corners, providing you with quality visual experience.


Step4
Appreciate the reverse 3:2 pulldown feature. Providing great quality pictures on TV requires processing the film into a video. It is a process to stretch and convert 24 frames of film onto 30 frames of video. Films that project at 24 frames per second are converted into 30 frames per second giving you a superior video quality. The reverse pulldown mechanism is important to slash the distortion created by progressive scan technology. As the new frames in the video are interlaced, it is not easy to find the original frame.


Step5
Check out the Picture in Picture (PIP) feature. Many times, you wonder how you can watch two channels or programs on the single screen. The PIP feature allows you to view your favorite TV show with a live sport event in small box, which can be moved around the four corners of the TV frame. The audio option is limited to one program, which you can choose. You can also flip the two programs from the main frame to the PIP box.


Step6
Explore the 3D Y/C Digital Comb Filter. It is the best type of comb filter available in the markets today. It separates the Y (Black and white) and C (color) elements from the video signal. This provides a superior picture quality. Additionally, it analyzes each frame of the picture in advance while comparing the three consecutive horizontal scan lines, thus ensuring best picture output.
