Video Cards, GPU, & Monitors By Patrick Laughrige Kofi Asante Will Tiller
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: 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 glassthat contain a liquid crystal material between them.
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 • Average Speed • World’s best GPU
Top VC • Amdradeon HD 6990 • NvidiaGeForce GTX 590 • ATI Radeon HD 5970
Where does VC go? • Video inputs • Alternative to HDMI
Other GPU/VC Facts • Average temp • Not overclocked • Overclocked temp • Main reason for upgrading VC
How to install VC • http://www.youtube.com/watch?v=5ILrq7lMe-0 • 1. Open case • 2.Remove old card & screws, replace new • 3. screw back in screws • 4. Update Drivers
