Carrying the computer in one’s bag is no longer necessary thanks to the invention of the monitor. The monitor’s primary function is to display text and images on its screen in an eye-catching manner, but it may also be used for editing or creating content.
A computer monitor is used to display a computer’s output. This can be text, graphics, photos, or video from the internet. The monitor is on the front of a computer case or a stand next to it.
Monitors can also be attached to TVs and other home entertainment devices. They are often found in offices where people use them routinely to get work done.
Function And Uses Of Computer Monitor
A monitor is a device that produces images from computer data. They are the central component of any graphic workstation and many other computing devices such as:
- Personal computers
- Video game consoles
Function Of The Monitor Screen
The screen portion of a monitor contains a grid of pixels that can display only a few colors. These limitations (the low resolution or color bit depth) can produce undesirable clarity for some applications.
At the same time, others do not have any practical limitations from the monitor’s point of view.
Since screens have been made for all types and sizes of displays in varying resolutions and color depth, monitors come in just about every size available to suit the application they are being used for.
A key element in moving a display around the computer is its position.
A monitor can be positioned horizontally, vertically, or in any combination (called “panning”) on the desk or other surface where it is being used.
However, many monitors are mounted on stands adjusted for height and lateral tilt.
There are three primary ergonomic design issues related to monitors:
- the screen should be positioned to avoid eye strain and maintain good posture.
- an adjustable stand is required to accommodate different heights of users.
- work surface height must be adjusted for each user.
Uses of computer monitors:
There are four major ergonomic design principles related to the use of monitors:
- Near-horizontal viewing angle
- Sit-to-stand height adjustment
- Elevation adjustment
Some individuals suffer a below-zero degree angle of view during normal use of a computer monitor.
Others, whose series-oriented jobs require extensive computer use, such as:
- System administrators
- Technical writers
They are often more subject to negative ergonomic factors related to the use of computers.
Precautions About Computer Monitors
A monitor does not emit any considerable amount of heat. However, it is recommended that monitors be kept away from radiators (e.g., a wall heater).
The heat from the monitors will cause the metal of the radiator to expand, and over a prolonged period, this could cause damage to the monitor.
Refresh Rate of Monitors
The refresh rate is how many times a monitor updates itself in a second. It is usually listed either in Hz (hertz) or kHz (kilohertz).
Refresh rates can be either interlaced or non-interlaced.
Non-interlaced monitors have been much more popular due to their faster response times than interlaced screens.
Monitors with built-in speakers provide sound output through the speakers, while monitors without built-in speakers provide sound output through an external amplifier/speaker setup.
Resolution of Monitors
The resolution of a monitor is the number of pixels in each dimension that can be displayed. The vertical resolution is often limited by:
- The display hardware
- LCD panels
- The number of pixels that can be sent to the panel without overloading it.
The most obvious effect of increasing vertical resolution is “taller” fonts and bigger windows if displayed side-by-side on the screen.
This makes more sense for word processing than spreadsheets since you typically use much shorter text lines than graphics.
A monitor with a vertical resolution might display some vertical pixels with a microsecond response time, while others require a minute or even hours to update.
This leads to the so-called “tearing” effect associated with many monitors and is often incorrectly blamed on the graphics cards.
The actual cause is the difference between what can be displayed in one application and what can be displayed in another application.
Common resolutions for computer monitors are
- 640×480 (VGA)
- 800×600 (SVGA)
- 1024×768 (XGA or UXGA)
- 1280×1024 (SXGA)
- 1440×900 (WSXGA+ or WUXGA)
The resolution usually gives the number of pixels on a monitor, so, for example, an LCD 16:10 monitor with a resolution of 1920×1200 will have 1920 pixels horizontally and 1200 vertically.
The TFT technology has made the production of large-screen sizes economically viable. LCD panels create CRT-type displays with higher resolutions without leaving the flat-panel form factor.
These flat panel displays can be made in sizes up to 40″ diagonal and larger. In computers, a monitor is the display screen of a computer.
- Monitors Usually Have A Flat panel (flat panel displays).
- May have an integrated flat-panel display (IPS).
- An LCD.
A monitor can be static or dynamic
Static monitors are designed only to display static images, while distribution monitors use very little electricity and display dynamic images without disturbing the user.
Since modern video cards are typically able to perform several simultaneous graphics operations. Whereas monitors only display one kind of pixel, there are multiple ways of resolving this problem:
- refresh rate (the number of refreshes performed per second).
- the refresh rate for each color component separately (i.e., 50 Hz = 50 times per second).
- refresh rate per plane (only as fast as the screen can be refreshed).
At common resolutions (e.g., 1024×768), a refresh rate of 60 Hz for each plane is usually required.
Although general-purpose computers with built-in graphics processors are used by many people today. High-performance graphics cards are often used to:
●Run graphic-intensive applications requiring, among other things.
●Better performance in computational and programming tasks.
●Show multimedia, including games and videos like movies.
In recent years, high-resolution monitors have become common in such applications, both on their own and especially as stencils glued onto flat panel displays.
The use of this technique requires a graphics card with at least 1 gigabyte of video memory.
Another method for increasing the resolution on a monitor involves using software rendering to draw text, images, and other objects projected onto a separate screen (a virtual screen).
The operating system typically does this in an environment called “virtual reality.” It is possible to use this method in software without expensive hardware such as VRAM.
Types of Monitor
A monitor is a device that displays information in electronic form. The most common type is the CRT or plasma display, but LCD and OLED monitors are also available.
Monitors are found in various devices, including computers, laptops, and televisions.
So What Exactly Does A Monitor Do?
A computer monitor shows what’s happening on your screen. It displays graphics and text that your computer sends to it.
Headsets help you hear sounds, like music or video game sound effects, coming from your PC speakers or TV set. The monitor also produces video images so you can watch movies and videos on it.”
The monitor is typically mounted on the desk but can be placed on top of a computer case or be attached directly to a computer motherboard and computer processor. A monitor can be connected to multiple source devices.
