Computer Monitors

Computer monitors are television-like devices used to display graphical information from a computer. They have been the primary form of displaying output to the computer user for decades. Questions about computer monitors and monitor display technologies belong here.

Do laptops have monitors?

yes Laptop have monitor but people calling it a display or LCD

Can you rewire a brain monitor or a heart monitor or one of those things that goes on your finger to have an audio output instead of a visual one?

Yes you can, but you need knowledge of electronics (personally i do not wish to go into detail because i do not know what you have/ know) its actually fairly simple, take the cord out of the monitor, then hook it up to a jack of any size. for example, a 1/4 inch for guitar amps. this will probably give a monotone, and may not be in the human hearing range. Most heart monitors are both visual and audio. In many cases, you just need a dongle to split the line coming from the heart monitor. It's small and kind of flat, like a slim SD media card reader and will have two plugs on it. Not sure on the brain montor, but most heart monitors after '88 do audio.

What is the operating system or systems software?

Operating system act like a manager between the system hardware and application software (Such as Firefox)

Also they do the fallowing tasks

  • CPU scheduling
  • Memory management
  • Inter-process communication

Can you use a monitor as the receiver of an extended tv?

The word MONITOR denotes a device that does not have its own tuner. To make a monitor act as a receiver all you need to do is add a outboard TUNER, Then it becomes a RECEIVER.

What is random scan graphics?

It is of 3-D

A single image random dot stereogram (SIRDS) is a computer-generated image consisting of seemingly random dots or lines, which, when viewed properly, coalesce into a previously unseen 3-D illusion. To see the hidden illusion, the viewer must relax the eyes and focus on a point in space behind the image. SIRDS work in the same way that stereoscopes, anaglyphs, and Polaroid 3-D movies do. Each eye receives a slightly different image, which the brain integrates into a single 3-D illusion. SIRDS became popular in the early 1990s with the Magic Eye series of books.

What is the meaning of 'resident monitor ' in an operating system?

it is piece of software that is use in early(1950-70) in genral computer in punch cards.

when the a program want to be executed in genral computer then insert a punch card and give the instruction of initial storage by pressing the button, after that the program was executed.

Is it possible to connect a TV tuner card to be used for CRT monitor to LCD monitor?

Yes. As long as the output is VGA. There is no difference in the standard between CRT and LCD.

Which gives a better measurement for the quality of an LCD monitor the contrast ratio or the dynamic contrast ratio?

The contrast between true black and true white on the screen. The higher the contrast ratio the better. 1000:1 is better than 700:1.

An advertised dynamic contrast ration is much higher than the contrast ratio, but not a true measurement of contrast. Dynamic contrast adjusts the backlighting to give the effect of an overall brighter or darker image.

What is a projector?

A projector simply projects images onto a wall or projection screen. Projectors are typically used to increase the image size for viewing by audiences. Projectors come in a variety of sizes, normally measured in Lumens which is the brightness of the light. This brightness will determine the size the image can project and the distance the projector can be from the screen. Slide projectors use light to project images from 35mm slides. Digital Projectors use light to project images from computers and DVD players.

Does a vga y splitter cable effect the video quality?

Video signals cannot be split in the same way that other signals such as audio signals can be split. The nature of the signal means that they demand an active splitter, normally called a distribution amplifier. The amplifier will generate two or more signals from the incoming signal, each with the correct voltage and impedance to drive a single input. A splitter that does not have a power supply is a passive one and they do not split the signal correctly. Always make sure you get an active unit (It will always have a power supply).

The quality of the image depends on the quality of the amplifier. Cheap distribution amplifiers are never as good as the best quality units. While you normally don't need to spend hundreds, it is worth avoiding the cheapest ones.

However, a bigger problem with many VGA signals is the cable used. Longer runs of VGA signals should be run on cable that has co-ax cables within the multi-core cable. It can be difficult to identify the cables but as a rule, thicker VGA cables will use co-ax cable inside. The thinner ones won't and they should be avoided for long cable runs. A good quality co-ax type cable will support a cable length of 100 feet or more. The cheap cables will show signs of signal degradation at as little as 10 - 15 feet.

When did flat screen tvs come out?

The world's first television system, The Televisor, by John Logie Baird is also the world's first flat screen television. The display used a backlight of varying intensity with a rotating disc in front of the light to act as a shutter. As the shutter exposed each part of the image, the lamp intensity was adjusted to create a light or dark area. The Televisor was first demonstrated to the public in 1925 and went into scheduled service by the BBC in 1929, so becoming the first regular broadcasts.

By the mid 1930s, the televisor was being replaced by cathode ray tubes. These have remained in use until plasma and LCD televisions once again made flat screen televisions available in the late 1990s.

LCD displays have been available from the 1980s but were limited in size and quality. The improvements in design and manufacturing have seen a gradual increase in both size and quality of image over the past two decades.

Can a computer camera connect directly to the monitor bypassing the computer?

No. The data needs to be interpreted and processed in order to be displayed, something that the monitor, itself, cannot do at present. If it could, there would be no need for a computer because the components of the computer would be integrated in the monitor.

Is the camera capable of doing so? Yes and no. The cameras of today are equipped with the basics for displaying images directly on their own integrated screens. However, as of yet, no tech is on the market to allow for plugging in a monitor to a cam.

There are, however, some printers that can interpret and process directly from the cam, bypassing the computer. Fun fact. :D

How does Dell xps M1530 display quality fare compared to M1330's LED backlit upgraded display?

The M1330s display would be BETTER Because backlit display is better for very dark games or movies, so a backlit display is best. The Dell XPS M1530 is good accept for a little bit darker screen. LED Backlit screens are designed to give you good brightness intensity.

How can I connect my PS4 to my Dell monitor- which is really old and doesn't have a HDMI cable port?

Use an adapter which would connect to the monitor and PS4. Old monitors usually have a VGA port. Look for a HDMI to VGA cable

Why deflection is necessary in cathode ray tube?

It is not necessary in a cathode ray tube, it is a side effect and is needed in the calculations to ensure that there are no errors.

Has anyone used a projector. i was just wondering if a projector can project my PC onto a wall instead of using my monitor?

Yes you can use a projector to display your computers output onto a projector, white wall/sheet. Keep in mind that a screen is designed to reflect much more light and color than you average white wall so the picture might not be as crisp as you want. Also keep in mind that the projector will have to have the correct input to match your computer output (VGA, HDMI, etc) or you have to have converters that will fit the inputs. Its a great way to play games, watch movies, office work, edit photos/videos, etc. You can find cheap projectors easy on eBay. Good luck Have Fun.

What is is the importance of monitor?

While an intrusion detection system monitors a network for threats from the outside, a network monitoring system monitors the network for problems caused by overloaded and/or crashed servers, network connections or other devices.

It is a subset of the functions involved in network management.
