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

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
