VGA represents a set of display standards for computer displays. The cable is a common interface for all VGA compliant devices and comprises several parts:
Red, green and blue signals
The three colors are used to create all colors and brightness levels. Each one uses a 75 ohm co-ax cable to carry the signals.
Synchronization signals
Horizontol and vertical sync pulses are carried on two wires with a single earth line.
Control signals
A monitor can communicate with a computer display driver using other data lines.
A VGA cable carries all of the signals listed above and typically will have 14 conductors inside the outer sheath of the cable. Some cables can use only 9 of the 14 conductors - still sufficient to carry a complete signal but will not carry any control signals.
The cables normally have to be compact to allow them to be terminated in a 15 pin high density D connector although VGA can also be connected using 5 BNC co-ax connectors.
Are CRT monitors completely obselete now?
They are extremely large in comparison to LCD monitors, and they require far more power. So yes, CRTs are typically considered obsolete by today's standards, especially with the introduction of LED LCDs, which have a far better black level and color contrast. LED/LCD monitors also have far greater resolution, since a typical CRT resolution is about 480i, while LED/LCDs can handle resolutions up to 4K. LED/LCDs have much sharper picture, due to higher resolution, and modern LED/LCDs don't have the motion blur problems that earlier LCDs had. These factors make modern LED/LCDs better than CRTs in almost every aspect, and are the cause of CRTs becoming obsolete.
Is a touch-sensitive display device that users interact with by touching the screen with a finger?
touch screen
A modem is a piece of hardware in which you plug a phone line into to connect to dial up internet access. PCI is simply the cards interface, in your situation it's a card that gets plugged into a PCI slot on your motherboard.
Where can one buy an Acer LCD monitor?
Acer LCD monitors can be purchased online and in your local computer or electronics store. Some people might sell a used Acer LCD monitor in which you can bid for this on a bidding website, or several websites that sells used computer equipment.
What is the purpose of an electricity usage monitor?
The purpose of a home energy monitor is to monitor the amount of electric and energy used in one's home. It can display the fossil fuel usage to and people who use them often reduce their energy use.
Which is durable led TV or lcd TV?
What do you mean by durable? The screens themselves are very delicate and will not react well to bumps or accidental impact from kids, pets, or overly emotional reactions from husbands watching the Sunday ballgame. I recommend wall mounting the unit to avoid the majority of these possibilities plus it looks fantastic and saves room. If you are talking about longevity, most new sets are rated for lamp lifes of 60000 hours. This is equivalent to having the set on for 8 hours a day for approx 20 years. Of course, 20 years is along time for other issues to occur. I have had my Sharp AQUOS for 3 years now and it is the same as the day I bought it.
LCD (liquid crystal display)
The combination will have a resistance of 100ohms, and will drew 144watts. But, the wall outlet will usually be fluctuating from 115V to 135V, 120V is't only a "reference". I suggest you measure it a voltmeter before doing any calculation.
Then, you can use this formula (ohms law) to find the correct answer : R = V/I
In our case : R(ohms) = 120V / 1.2A R = 100ohms
What is the meaning of monitor and what is the duties of a monitors?
It is a device connected to a computer that displays information on a screen.
A monitor can also be a person who watches. For example, a monitor could be present while a test is being taken to ensure that all test-takers follow the rules for that test.
Can you connect two computers to one monitor without using a switch?
I believe that it is possible to connect to computers to one monitor. I have worked with brand new LCD monitors with two inputs - one DVI and one VGA. The monitor auto-senses which port is being used. So in theory, use the auto detect button on the front of the LCD panel to switch between computers.
Where can one purchase a 23 inch LCD monitor?
Future Shop, Computer Sense, Best Buy, or Wal Mart are great starting places to look for purchasing a 32 inch computer monitor. Depending on where you purchase and whether you want a flat screen will change the price.
Why your computer screen flickers and goes black?
My monitor flickered, informed me to check connection, and then went black. If you unplug the monitor from the computer and it goes black then it's not the computer or malware....it's the monitor going out. I bought a new monitor and everything is working fine again.
Is PC and laptop both are same?
Notebooks and Laptops are the same thing. Both words mean the same computer however a Netbook is where the difference is. A Netbook is usually a computer that has less hardware then the average laptop or notebook. Most Netbooks do not have a CDROM, they are smaller (7-12 inches) and they cost a lot cheaper then the average laptop.
A three dimensional display utilizes a varifocal vibrating mirror which reflects the screen on a CRT. The varifocal mirror is vibrated at a rate synchronous with creation of frames on the point plotting CRT. A video source is utilized of the type having red, green and blue outputs utilized for normally creating color display. However, the coding is such that what would normally be interpreted as red, green and blue outputs of the video source are instead interpreted as x position, y position and intensity information for a CRT accepting x, y and i signals. A depth or z coordinate is implicitly encoded in the video source at the position within a single frame of the video source where the corresponding (x, y and i) values are stored. This position can be the relative position on a magnetic or optical disc, or position around a magnetic drum. In one embodiment of the invention a raster graphics system utilizing a frame buffer is utilized. The frame buffer is divided into buckets, and the particular bucket within the frame buffer where an (x, y, i) display point is stored corresponds to the z value or depth coordinate of that point. Techniques are disclosed for interactive modification of three dimensional displays utilizing the look-up tables and registers in a standard raster graphics display system for achieving image rotation, transformation, scaling, spatial windowing, intensity windowing, cursor control, cursor inking, and blinking.
An LCD TV is exactly an LCD screen with fluorescent lighting shining through it. Without the light, you could see very little on the screen.
An LED TV is exactly an LCD screen with LEDs behind the LCD screen shining through it. The LED lighting gives more even color and brightness on all pixels, and results in a sharper image with more 'pop'.

The LCD projector was invented by New York inventor Gene Dolgoff. He began working on it in college in 1968 as a way to produce a video projector that would be brighter than the then-available 3-CRT projectors. The idea was to use an element referred to as a "light valve" to regulate the amount of light that passes through it. This would allow the use of a very powerful external light source. After trying many different materials, he settled on liquid crystals to modulate the light in 1971. It took him until 1984 to get an addressable liquid crystal display (LCD), which is when he built the world's first LCD projector. After building it, he saw many problems that had to be corrected including major light losses and very noticeable pixels. He then invented new optical methods to create a high efficiency and high-brightness projector and invented depixelization to elliminate the appearance of the pixels. With patents all around the world, he started Projectavision, Inc. in 1988, the world's first LCD projector company, which he took public on Nasdaq in 1990. He licensed the technology to other companies such as Panasonic and Samsung. This technology and company started the digital projection industry. In 1989 he was awarded the first Darpa contract ($1 million) for proposing that the US HDTV standard should use digital processing and projection. As a member of the National Association of Photographic Manufacturers (NAPM) Standards Subcommittee, IT7-3, he along with Leon Shapiro, co-developed the worldwide ANSI standard for measurement of brightness, contrast, and resolution of electronic projectors.

Why can't tv be used as computer monitor?
It can. Most graphics cards do not have a TV output, so you will need to buy a converter of some type.
