How can you present one image in a 4 TVs screen by distribute the image in to 4 corner?
This application generally requires some sort of video processor. The process is image scaling and it allows the zooming in of a portion of an image on one of 4 screens. Basically this is known as video wall processing. Solutions can be found at Jupiter systems RGB Spectrum Aurora Multimedia Avertech TVOne Many commercial TVs have processors built-in.

screen capture
Why does the picture on the tv screen become distorted when a magnet is brought near the screen?
A strong enough magnet brought close enough to the screen or to certain other parts of a television or computer monitor that uses a cathode ray tube will distort the displayed image. This happens because a cathode ray tube image is created by shooting electrons at a phosphor-coated layer that glows where the electron stream strikes it. The stream of electrons is focused and targeted by magnetic fields within the TV tube. A strong enough magnetic field from another source will send the beam of electrons off target, distorting the image. This does NOT happen with modern flat screen TVs and computer monitors because they do not use cathode ray tube technology to create the image. The picture as seen on TV screen is due to moving charged particles (electrons).
How do manufacturers define the size of a 42 or 36 inch television?
Screen size is measured diagonally in inches between opposite corners of the screen.
What termed of the length of time an image stays on the screen after the signal is removed?
Persistence.However, it should be understood that there is both physical persistence, i.e. the time the image stays on the screen, and biological persistence, i.e. the time the human eye continues to perceive the image.
How many pixel in one inch?
Depend on image resolution. You can see image resolution in Photoshop from Image > Image Size. Pixels are just the tiny dots that form images, they are not a form of distance measurement. To demostrate this, take for example a 40 in. TV. That 40 inch TV might contain 1920 x 1080 pixels to make up the screen, but likewise, a computer screen that is only 20 in. can also have the same amount of pixels.

How do large projection tvs work?
Large projection TV's work by making a small image and projecting it onto a larger screen exactly like a projector. The problem with these is that the image is not sharp unless you look directly straight at the screen.
What is a video projector used fo?
Let's say that you want to have a really large-screen TV but can't afford one, or don't have the space for one. You can use a video projector to create a large TV image on any blank wall. You might need to make the room a little darker, because the projector will have a dimmer image than a backlit TV screen.
How do separate color channels mix together to form an image?
THE TV HAS WHAT IS CALLED A FILTER SCREEN WHICH WHEN IN OLDER TV'S WOULD BE BOMBARDED WITH ELECTRON BEAMS OF BLUE, GREEN, AND RED TO MAKE THE COLORS THUS YOU HAVE PINK, PURPLE, ORANGE, ETC... THE FILTER SCREEN IS NEXT TO ANOTHER TYPE OF SCREEN (I FORGOT THE NAME) WHICH DIRECTS THE BEAMS IN SPECIAL WAYS TO MAKE COLORS AND IMAGES. THE PIXELS ON THE SCREEN ARE INDIVIDUAL COLOR SPOTS WHICH MAKE UP THE IMAGE WHEN PUT IN A SPECIAL ORDER. THAT'S HOW SEPARATE COLOR CHANNELS MIX TOGETHER TO FORM A SPECIFIC IMAGE. this question was answered by Paul/Wolf 10th grade from Shorewood Christian School.
How do wide screen TV's deal with non-wide screen broadcasts?
Widescreen television formats have made an appearance in recent years. In Europe, widescreen (16 : 9 format) has been used widely for a number of years using standard definition broadcasting while in North America, widescreen has only been used with high definition broadcasting. In both cases, the change of shape has to be handled. All widescreen televisions will have their own way to deal with a 4 : 3 ratio image. The simplest method is to center the image on the screen and leave side curtains (black or gray areas) to fill the remainder of the screen. Most will allow the image to be stretched to fill the screen with the result that all images are mis-shapen. The last common method is to enlarge the whole of the image so that the width of the image fills the screen and the top and bottom of the image are lost. Some televisions allow the image to be panned to bias the zoomed image towards the top or bottom depending on the content. Broadcasters often have to cope with the same issues. Although the channel might be broadcast in widescreen, some of the content may still be 4 : 3. The image will be handled in the same ways as a domestic television but it is important to note that if side curtains are added to the image, the output is still in the wide screen format and the image cannot then be resized on the domestic television. In standard definition widescreen, a "wide screen signal" is used (WSS) within the television signal to tell the receiver what format the image is in. It is this WSS signal that is detected to establish what shape of image the television needs to use. WSS is never used in high definition as all HD images are widescreen.
What is the difference between plasma screen and lcd panel?
Plasma screen TVs use certain cells that release a special type of gas to produce the image on the screen. LCD TVs give off the image by using the light modulating properties of liquid crystals (LC; LCD is short for "Liquid Crystal Display.")
Why is there a boat floating on your Blu-ray screen?
Older TVs were prone to what was called a "Burn In" where if an image appeared on the screen for too long it would become burnt into the screen. Newer TVs don't have this problem, but these "Screen Savers" still exist as a legacy purpose.
What appears after your computer is idle for a specified period of time?
Usually the 'screen-saver'. If a TV or computer screen is left on with the same image, it can 'burn' the image onto the screen - creating 'ghosting'. A screen-saver allows your computer to stay on - while protecting the screen's pixels.
Can you put a giant polarized screen on your 3d tv to get the 3d image?
