Widescreen Televisions - Buyers GuideWidescreen Features
16:9 Some TV broadcasts and DVDs have extra horizontal lines of resolution, to optimise the picture quality on a widescreen TV. Such images will look vertically stretched if you don't use the widescreen 16:9 mode. 
Zoom Some movies are filmed using an aspect ratio that’s even wider than a widescreen TV, and so will appear with small black bars above and below. Zoom modes magnify such images so that they completely fill the screen. 
4:3 Widescreen TVs 4:3 or regular mode allows you to watch programmes broadcast in the traditional square shape, in their correct proportions, by putting black bars down each side of the screen. Most widescreen TVs can automatically stretch the 4:3 pictures to fill the wider screen. Widescreen Features A new breed of TV has arrived: Flatscreen Three Good Reasons To Think Flat. 1. Flat TVs suffer much less with on-screen reflections. 
2. Flat TV pictures don’t become curved in the corners limiting picture distortions and making text easier to read 
3. You can watch flat TVs from a much wider viewing angle 
How Do They Do It? Stepping Up To A Better Picture Ever wondered why some TVs cost more than others? Then join us as we take a trip through some of the advanced technologies being used to take your viewing experience to the next level 100 Hz Your first major port of call when stepping up from a basic TV is a feature called 100Hz. On standard TVs, the picture is shown at a frequency of 50Hz, which can cause flickering on a big screen. 100Hz TVs use digital processing to double the frequency rate, which removes all traces of flicker and makes the image look more vibrant. 
Why Should I Use A Scart Lead? For high quality images and sound a Scart lead is essential 
1. A Scart lead transfers pictures and sound directly to your TV. The signal bypasses the TV internal tuner, cutting out resistance and reducing picture interference. 2. A Scart lead also enables stereo sound such as Dolby Pro Logic to be transferred during video playback. Why do some cost more? 
The more expensive Scarts take extra measures - such as using gold connections and thicker wiring - to keep picture interference to a minimum. More expensive ones will also be more durable.
DRC Extract the finer detail from all visuals. Sony’s Digital Reality Creation system essentially adds more fine detail to your pictures. It analyses incoming images and completely redraws them with more pixels of resolution. There are two DRC-MF modes: DRC 50 and DRC 100. DRC 50 creates double the number of horizontal AND vertical lines in the picture, giving you four times the previous resolution. DRC100 is the 100Hz interpretation of DRC. It doubles the scanning frequency and the number of horizontal lines in the picture, but doesn’t give quite such a step-up in resolution as DRC 50 since it leaves the number of vertical lines unchanged. 
Natural Motion Digital technology that creates smoother moving pictures 
An innovation found on some Philips TVs. It analyses movement in a broadcast, video or DVD and uses a digital memory to create new frames of picture information between the frames present in the original footage. Fast-moving objects thus look sharper and seem to cross the screen much more smoothly. Pixel Plus Making your pictures sharper, more detailed, and just plain better Pixel Plus combines unique image processing technologies to give you an unprecedented image quality, irrespective of source material, from broadcast, video tape and gaming to DVD and digital TV signals. It also achieves better depth impression so you get images that are more life-like and three-dimensional. Images on a TV are actually formed by lines across the screen. A standard television picture is made up of 625 lines with 1024 pixels or picture details on each line. Pixel Plus Technology creates 833 lines and 2048 pixels on each line. The result: double the horizontal resolution of a standard TV and an increase in vertical resolution by one third. Watching TV has never been this enjoyable which such vivid visuals that leave nothing to the imagination 
Acuity Delivering pin sharp focus, brightness and high resolution Acuity, from Panasonic is a high-end processing circuitry, which delivers the ultimate in picture performance with pin sharp focus, brightness and high resolution. The word Acuity is derived from the word acute, meaning sharpness. Images on a TV are actually formed by lines across the screen. A standard television picture is made up of 625 lines with 1024 pixels or picture details on each line. Acuity technology delivers 833 lines and more than 2300 pixels per line. The result is a horizontal resolution of more than double that of a standard TV and a one third improvement in vertical resolution. Combine this with the effective frame rate conversion which reduces judder and flicker. And the Acuity processing power that has been increased to 10-bit on both luminance and chrominance signals. Panasonic TVs with Acuity deliver unequalled sharpness, depth and detail.
