My first assgn on monitors

We had learned on Monitors the two most common types LCD-Liquid Crystal Display, CRT- Cathode Ray Tube.

Now how LCD monitors work- the liquid crystal that is stored between two thin pieces of glass reacts to an electrical signal and gets "excited". Their refresh rate isnt as high as the rate of CRT's . The refresh rate depends on how fast the lights change.Though if u press on the front glass the place becomes weird for some time.

Now for CRT's is different they use rays of light which combine into other colours because of the refresh rate which is faster so video games and movies.

Next point how the screen is measured each dot is called a pixel (picture element) which the screen contains. the moer the dots the bigger the monitor. Plus the screen has a resolution -how many pixels it could fit wide and long. So Modern computers would usually have a resolution of 1024x768 pixels. The bigger the resolution the clearer the picture there is less noise (ex. wen in photoshop u zoom in, the noise appears, as u could see whats happenin on the screen).

Monitors are well measured. The are measured in diagnol. FOr the LCD monitors u measure everything u see since the plastic case does not cover glass. The again for CRT monitors its a completely different situation. About an inch on each side of the plastic that surrounds the tube covers the tube.. When measuring the size of your CRT monitor remember abt the plastic bit n that measure the viewable part but also the plastic bit(but the viewable part maybe viewed for other purposes).
