Monitor Display Technology
Monitor displays use liquid crystal display (LCD) or cathode ray tube
(CRT) technology
Resolution is also a factor when it comes to monitors. It’s the number
of individual dots of color, known as pixels, contained on a display.
Resolution is expressed by identifying the number of pixels on the
horizontal axis (rows) and the number on the vertical axis (columns),
such as 800x600.
Resolution is affected by a number of factors, including the size of the
screen.
Monitors: ResolutionStandard Resolution Typical Use
XGA (Extended Graphics Array)
1024x768 15- and 17-inch CRT
monitors15-inch LCD monitors
SXGA (Super XGA) 1280x1024
15- and 17-inch CRT monitors
17-and 19-inch LCD monitors
UXGA (Ultra XGA) 1600x1200 19-, 20-, 21-inch CRT
monitors20-inch LCD monitors
QXGA (Quad XGA) 2048x1536 21-inch and larger
CRT monitors
WXGA (Wide XGA) 1280x800 Wide aspect 15.4-inch

WUXGA (Wide Ultra XGA)
1920x1200 Wide aspect 22-inch
and larger LCD monitors
Monitors: Aspect ratio & Viewable area
Two measures describe the size of your display: the aspect
ratio and the screen size
computer displays, like most televisions, have had an
aspect ratio of 4:3. This means that the ratio of the width
of the display screen to the height is 4 to 3.
For widescreen LCD monitors, the aspect ratio is 16:9
Screen sizes are normally measured in inches from one
corner to the corner diagonally across from it
Monitor: Analog Connections
Most CRT monitors require the signal information in analog form
The computer and video adapter convert digital data into analog format.
Once the display information is in analog form, it’s sent to the monitor through a VGA cable.
Monitor: DVI Connection
DVI keeps data in digital form from the computer to the monitor.
LCD monitors work in a digital mode and support the DVI format
The DVI specification is based on Transition Minimized Differential Signaling (TMDS) and provides a high-speed digital interface.
DVI cables can be a single link cable that uses one TMDS transmitter or a dual link cable with two transmitters.
LCD Monitors
Liquid crystal display technology works by blocking light
LCD is made of two pieces of polarized glass that contain a liquid crystal material between them.
Video Cards
What is a video card and what does it do?
Video Cards receive binary data from the CPU and turn it into pictures you can see
The CPU and Software Applications send info to the Video Card, which then sends the information to the monitor.
How to select a video card
Large amount of memory space Fast Processor Frame Rate- amount of images
displayed per second Triangles per second Pixell fill rate Compare Hardware Specs- Large Range
How to Install
Must be compatible with the buses on motherboard
If the motherboard has onboard video, disable the onboard video in the BIOS when installing a card in the bus slot
Place in slot and configure
Troubleshooting
System does not boot Incorrect colors Blurry Images Slow Video Performance Screen Flickers
Benefits of Upgrade
Improved Graphics, Video capabilities Overall Efficiency Increase
GPU: What it does Main Function used in phones, personal computers,
workstations, and game consoles
Laptop Replacement problems
