In LED monitors what does LED stands for?
LED means "light emitting diode." That is a semiconductor that produces light. LEDs are found on various parts of a computer. Some are used such as on the front panel to show that the computer is in use. Some are used for status lights, speed indicators, temperature gauges, and for decoration.
Then of course there are LED-based computer monitors. They use an entire sheet of many tiny LEDs which are connected to driver circuitry and are used the same way as traditional CRT-based computer monitors. The overall result is the same - electrons excite a rare material and cause it to glow, but the method is different. CRT monitors used a high voltage electron beam to strike phosphors on the front of the CRT tube. LED and LCD monitors use lower voltage that is directly applied to the material, and the result is the same - it glows.

How 1600 x 1600 pixels in inches?
There is no way to give a real answer for that. Pixels do not have a consistent size, so they can't be universally converted. Pixels change size depending on the density of the thing displaying them (72 dots per inch is typical for screens and 300 dpi is typically selected for something that will be printed as form of Quality Photo). For screens size differs based on "Pitch" of the screen(distance between two consecutive pixels) thus even small screens with low pitch value can display high resolutions!
However, to simply measure the width and height of your monitor at high accuracy just use the "Jruler" application

How do you be good class monitor?
You may be asked to help set up the classroom just as the teacher wants it, moving any chairs or tables as needed. Occasionally, you may need to sweep the classroom and wipe the desks and chairs down with a rag or dust cloth.
You may serve as the liaison for new students, helping to acclimate them to the layout of the school and the school's social climate. You may also take work to sick or injured students who have missed class.
You may help create a class telephone and email list and may use an attendance list to take daily attendance. You may also help recruit people into elective classes if there are empty spaces.
As class monitor, you may also help the teacher promote discipline and peace in the classroom. You may be given the power to send students to the principal, to detention or to another authority within the school when students misbehave. You will also be given a school policy book so that you can help enforce the school rules.
What is the most common way to connect a computer to a monitor?
For years the most common connector has been a VGA or DB-15 analog connector. Most laptops still use the analog connection. However, today the Digital Visual Interface (DVI) is becoming the standard. There are several styles of DVI connector.
See links below for more complete explanations of these connectors.
the various shades / tints of gray between white and black - the human eye cant see very many shades so 256 shades is enough to cover what the eye can see - which is why a gif image with 256 levels can show black and white photos perfectly but not color photos which require millions of combinations
How can you get a pear laptop?
You cannot get a pear laptop. Though the pear laptop has been seen on popular TV programs, it is imitating Apple, but the program would get sued for using Apple on the program, so they slappped a pear skin on apple products so Apple couldn't sue the program. They are not available anywhere. Even if you could get a pear laptop, it is just a stage prop; it will not do anything.
What is the proper way to clean flat screen tv's monitors?
NEVER use any fluids to clean an LCD screen. Use a dry and soft cloth (not paper, it contains wood pieces which could scratch your screen). If this doesn't help, use lightly wetted anti-static monitor wipes ESPECIALLY designed to clean such screens. They are widely available at electronics or office supply stores. Also, on the packaging look for the designation: Safe for Laptops and LCD screens. But always be very careful! You can purchase a cleaning solution from any electronics store, perhaps the one you bought the TV from and this will do the job. Follow instructions on the container. Whatever you do, do not use alcohol based products, it will do some serious damage to your screen over time. Spend 5 bucks and go to the store and buy the cleaners and a really soft rag. Do not use the conventional products like Windex etc. Also make sure your screen is off when you do it for a little while. If you don't, you are heating up the chemicals and making them dry faster. Your screen might not feel warm but it's the reaction of light with the chemicals. Lay the screen flat, too. To keep your screen cleaner longer, try not to touch the screen. To dust it (tissue may leave dust), I use an old draftsman's brush, but a Swiffer duster would likely work as well. The ideal solution is plain distilled water. If more heavy cleaning is needed a 50/50 mix of white vinegar and distilled water can also effective. Manufacturers no longer recommend using any cleaners with alcohol, ammonia or any strong solvents on LCD screens.
Is CRT a type of computer monitor?
Yes. A CRT stands for cathode ray tube. This was the de facto type of display screen for TVs and early computer monitors before the implementation of LCD, LED, and OLED screens later on.
Unlike the other types of display, this type of display was susceptible to magnets and magnetic fields, which will tend to mess it up. That 's why if you see a CRT monitor back then and now (if there are still any manufactured at all), there will be a degauss button to help with that.
In addition, the screen saver was actually designed during this era to prevent the screen from permanently burning a image onto the screen for having a certain pattern stay on the screen for too long (thus the term "screen saver"). Now it's not much of an issue with newer monitors and TVs, but current screen savers are kept more for a fashion statement and for security/privacy concerns.
You can connect one projector by HDMI and the other by VGA. This will allow you to connect two projectors to your computer.

Can you use a gateway monitor witha Dell computer?
It is almost certainly possible.
The monitor should connect via either VGA (a large plug with three rows of pins) or DVI (an even larger plug with several rows of pins and one large flat pin). VGA plugs are often blue and DVI plugs are often white. Almost any computer will have a VGA out, many have DVI out.
These are standard across all monitors and computers, regardless of manufacturer.
What is the number of pixels used to display information on screen?
The different monitor resolutions are not exactly standardized, but they are generally manufactured according to a pair of numbers...the number of pixels across and up-and-down. For example, the old VGA stood for 640x480 pixels. W in front of the abbreviation means "wide," and means something closer to a 16:9 aspect ratio, rather than 4:3. Look to the word "resolution" for more information.
What is the shape of a monitor?
HD screens have an aspect ratio of 16 : 9.
Standard definition televisions can be either 16 : 9 or 4 : 3. The widescreen ratio for SD televisions was introduced in Europe around 1990 but was not used in North America.
A liquid crystal display (LCD) is a thin, flat electronic visual display that uses the light modulating properties of liquid crystals (LCs). LCs do not emit light directly.
They are used in a wide range of applications, including computer monitors, television, instrument panels, aircraft cockpit displays, signage, etc. They are common in consumer devices such as video players, gaming devices, clocks, watches, calculators, andtelephones. LCDs have displaced cathode ray tube (CRT) displays in most applications. They are usually more compact, lightweight, portable, less expensive, more reliable, and easier on the eyes.[citation needed] They are available in a wider range of screen sizes than CRT and plasma displays, and since they do not use phosphors, they cannot suffer image burn-in.
LCDs are more energy efficient and offer safer disposal than CRTs. Its low electrical power consumption enables it to be used in battery-powered electronic equipment. It is anelectronically-modulated optical device made up of any number of pixels filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in colour or monochrome. The earliest discovery leading to the development of LCD technology, the discovery of liquid crystals, dates from 1888.[1] By 2008, worldwide sales of televisions with LCD screens had surpassed the sale of CRT units.
Why do computer screens blackout momentarily?
There are multiple reasons for a screen going black:
A) If your computer is running low on power, it may put itself to sleep just before it shuts off. I have had this happen to my computer tons of times
B) Depending on your settings, you may have your sleep mode set really short. You can easily fix this by going into your control panel and playing with the settings you desire. The computer will go to sleep mode after however many minutes of inactivity it is set for.
C) If there are no lights flashing or anything running with the computer, it is most likely shut down. In this case, find the power button, turn it back on, and enjoy.
D) If you own a separate monitor for your computer and your computer is running, one of the wires may be loose or the monitor itself may not be turned on. Unplugging and replugging wires seems to be a good strategy.
How much will it cost to repair your broken computer screen?

How do you monitor clients need and requirements?
Answer
To know what a client needs and what the requirements are, you ask that person for a meeting based upon the above mentioned aspects of the job. He or she will come to meet you and bring charts and business incentives so that you will know what they need and then you can go about preparing whatever it is that they need. You only have to ask, it's that simple.
