Computer Monitors

There are many small transformers and electronic oscillators in a CRT monitor which scan the electrons across the screen, blank them at the end of a line and return the beam to the left of the screen in order to start the scan again. These transformers have alternating currents flowing through them which make the ferrite cores 'chatter' at the same frequency. This frequency is about 18,000 cycles per second which makes this audible noise.

There two different colours

HA HA

No, the difference is that a green screen is more commonly heard of!

But in ICT it is the exact same

Both are differ in colors

The measurements used to determine a monitors screen resolution is Pixels per Inch (PPI). The size of a monitor in inches and the total pixels in the horizontal and vertical directions determines the PPI of the screens resolution. For Example a 15 inch monitor has a maximum of 1024x768 pixel resolution.

No, unless you use third - party software

It uses binary to create pixels. There are three parts to a pixel; the X coordinate, the Y coordinate, and the color. There is a sort of grid system. The X and Y coordinates tell the monitor where to place the pixel, while the color tells it what color to change it to. The combination of all the millions of pixels creates a picture on-screen.

CRT stands for Cathode Ray Tube.

In laymans terms a CRT monitor is the old-style glass tube monitor we all used for years and years before flatpanel monitors became cheap & popular.

CMOS is not RAM. While it is memory, unlike main system RAM, CMOS is very tiny and only holds the BIOS configuration, nothing else. RAM is made from transistors and capacitors, which must be recharged. CMOS is made from several transistors wired as flip flops. It only needs a tiny amount of power to hold its data, and that comes from a small battery. If you remove the battery, it will lose everything.

Second answer: If your computer has only a vga plug/socket this is where you plug it in,it's usually blue.It has 15 pins on the plug from the monitor.If it doesn't work from this arrangement,you have to get a vga to dvi adapter.

The answer depends on your monitor model, of course.

For some of the LCD models you may reset the monitor by pressing (and releasing) the "MENU" button (OSD menu appears) then hold the "SOURCE" button for a few seconds. When you see the monitor blinks it means that reset was done.

Printer & Monitor are not input device, these are output devices.

Dot pitch is a measure of the distance between pixels. The smaller the dot pitch, the better the picture.

Minimum 70Watts. It might be as high AZ 90-100 even 120Watts - it depends on the monitor. There is no standard rating.

A screen/monitor that only shows one color except for black. Like a black and white TV or a green and black cell-phone screen.

1. CRT (cathrode ray tube) is used in very old computer monitors and televisions. LCD (liquid crystal display) is used for flat screens
2. CRT are no energy efficient,LCD are energy efficient
3. LCD - compact , portable, light weighted, CRT- weighted, and large in size as compared to LCD
4. LCD- uses liquid crystals to form the images, CRT- uses a cathode ray tube or electron gun to form the images

It is still customary to measure, in inches, a screen from corner to corner diagonally.

Anything that doesn't allow light to pass through ! Some examples would be:- Bricks, wooden boards, heavy curtains or black plastic bags...
