Monitors...

The monitors works with a video card,located inside the computer case,to display image and text on the screen.


  • Newer monitors usually have LCD (liquid crystal display) or LED (light emitting diode) display.
  • These ca be made very thin,and they are often called flat-pannel display.
  • Older monitors use the CRT display.
  • CRT monitors are very large and havy weight.

Monitor type: 

1.Digital monitor:
  • The older monitor which use MDA ,CGA and EGA video standers are called digital monitor.
  • The data describing the pixel colors are sent from the video adapter to the monitor in a series of digital signals which are stream of data bits. 

2.Analog Monitor:
  • The analog type monitors use the VGA standers.
  • The VGA standards allow transfer the color information from the video adapter to the monitor as analog signal.
  • Analog monitor are support 256 different color.Whatsapp plus+

3.Multi-scanning monitor:
  • These monitor can be connected to a wide variety of video board and they can be sued with analog or digital video adapter.
  • They can switch auto or manual for working analog or digital monitor.
  • They contain more sophisticated electronics circuit which gives more flexibility to work on different display standards.

CRT monitor:




  • The pc monitor is a primary output devices which can display text and graphics on its CRT screen.
  • The monitor contain a large vacuum tube that is similar to one found in a television (TV).
  • The front part is tube where we seen the text and graphics and rear part contains electron guns which is surrounded by control circuit.
  • The monochrome monitor contain single gun while color monitor contain three guns for emission of electron.if you want clansh of clans mod apk click

Flat panel display (FDP) monitor:


  • FPD are thin, bright display output that are gaining a foothold on desktops as a replacement for traditional CRT monitor.
  • The most obvious benefit is the much smaller amount of desk space required,because there is no big case housing the electron gun,nor a heavy glass front.
  • Because they dont rely on transitory phosphors to create an image , they are free from flicker.
  • FPD are also two to three times brighter than CRT screen.Since the screen is flat,this means that is no distored image at the edge of the view area,as there is with curved CRT monitor.
  • FPD are generally easier on the eyes and dont require a "warm-up" period to reach full color saturation.
  • FPD create an image made of pixel,just like their CRT counterparts , but they use different technology to accomplish that task.
  • Several different type of FPD are available today,varying in cost,image quality.gbwhatsapp apk
