					Flat panel monitor characteristics

 Screen size
 Viewing angle
 Response rate— How quickly the pixels change color.
 Contrast ratio– the ratio btn the monitor’s brightest white and
  darkest black. 400: 1 to 600:1
 Native resolution– the number of individually addressable pixels
    in the screen matrix.
 Brightness/luminescence                    measured in candelas per square
    meter   (cd/m2).   Average is 250 to 500cd/m2
 Other features
   Change orientation
   Built-in speakers
   Anti-theft lock
   Wall mounting
   Built in USB hub
Flat panel monitor connections
 Connection types
     15-pin VGA style connection cable
     DVI-D (dual link Digital Video Interface) digital only
     DVI-I– digital and analog
DVI-D
 Digital-only connection
 Dual-link contains 24 pins in 3 rows of 8 plus
  a grounding slot
 Single-link contains 18 pins
DVI-D connector

                  DVI-I connector
DVI-I
 Supports digital and analog signals
 DVI-I contains 4 additional pins over DVI-D
 Extra 4-pins carry analog signals
 Analog signal pins located above and below
  the grounding slot
TMDS--Transition minimized
differential signaling

  Protocol used to transmit data to digital
   monitor
  No analog conversion
  Single-link cables use one TDMS transmitter
  Dual-link cables use two TDMS transmitters
  Supported resolutions
       Single-link up to 1920x1080
       Dual-link up to 2048x1596
Touch screen
 Touch-sensitive surface
     Pressure-sensitive resistors
     Infrared sensors
     Electronic capacitors
 Uses
