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

Common Monitor Issues
1) Old monitors lose brightness, may need backlight replaced
2) Bad pixels (white = stuck/lit) (black = dead) (color = lit)
3) Flickering may be issue with panel or backlight
4) Hissing probably a dying inverter
5) Image Persistance needs power down, leave off as long as was on
6) Image Burn in you fucked, replace monitor
Troubleshooting Drivers?
Boot into safe mode, rollback update
