Chapter 17: Display Technologies Flashcards
Display Adapter
Device that handles communications between the CPU and monitor (typically a card)
LCD
Display technology of crystals held in an array between polarizing filters
sub-pixel
A crystal that represents either R, G, or B. A set of three equal 1 pixel
Basic Display Parts
Panel, backlight, inverter for non-LED displays
3 types of display tech
1) Twisted Nematic (TN) - fastest, ok color
2) Inplane Switching (IPS) - slower, good color
3) Vertical Alignment (VA) - midrange option
Projector Image Technologies
1) LCD - throws LCD image to screen
2) DLP (Digital Light Processing) - internal mirrors, no native resolution and better color
Lumen Requirements by Space/Room
Dark Room: 1000 - 15000
Medium room w/ light: at least 2000
Large Spaces: at least 10,000
Projector Lighting Technologies
Lamps: slow to heat up, expensive, hot, about 3,000 hours
LEDs: faster, cheaper, less bright, about 30,000 hours
Laser: faster, cheaper, good colors, about 20,000 hours
Types of DVI
DVI-D (Digital)
DVI-A (Analog)
DVI-I (Interchangeable)
Thunderbolt Versions
Thunderbolt 1&2 - miniDP
Thunderbolt 3&4 - USB-C
Card Connections to MoBo
PCIe connection
Use PCIe x16
Older:
PCI - Peripheral Component Interconnect
AGP - Accelerated Graphics Port
3 Bottlenecks of Video Memory
1) Data throughput
2) Access Speed
3) Capacity
Special RAM for GPU
1) GDDR (Graphics DDR)
2) HBM (High Bandwidth Memory)
Capture Card
Designed for recording/streaming, will have external ports
3 Concerns when Installing Video Cards
1) Long Cards - high-end cards may not fit in case, block mobo connections
2) Proximity of nearest expansion cards - GPUs get very hot, expect to take up 2-3 slots
3) Presence of Power Connectors - high-end cards may need addition power, check pins (6 v 8) and availablity
