What feature of a non-interlaced monitor makes it a better quality than an interlaced monitor?
Interlaced monitors can cause headaches and eyestrain. Non interlaced monitors produce less flicker.
What is screen size?
1. The physical screen size. (measured diagonally)
2.The effective viewing size
What is resolution?
The number of pixels available on a display screen.
What resolutions used by HDTV?
1. 1280 x 720
2. 1920 x 1080
What is the dot pitch?
The distance between pixels. (Measured in millimeters)
What is refresh rate?
The refresh rate is the amount of time required for the image to be created on a CRT from top to bottom.
What is interlacing?
Interlacing is drawing the screen in two passes: odd first and then even.
What are Green monitors?
Energy Star compliant monitors that use less than 30 watts.
What is contrast ratio?
The difference in light intensity between the brightest bright and the darkest black.
What does a higher contrast ratio indicate?
Better quality picture.
What is the static contrast ratio?
The difference in light intensity between the brightest bright and the darkest black that can be displayed on the screen at the same time.
What is dynamic contrast ratio?
The difference in light intensity between the brightest bright and the darkest black that the monitor is capable of producing
What is the response time?
How quickly a pixel can go from black, to white and back to black. (Measured in milliseconds)
What does a lower response time indicate?
A quicker response time.
What happens if your response rate is too slow?
A slow response rate results in ghosting or blurred images.
Which LCD display type typically has the fastest response time?
Twisted Nematic (TN) TN monitors
What is brightness/ luminance?
The amount of light that the monitor produces. (How bright it is)
What is the viewing angle?
The angle at which the image can still be seen.
What is the pixel pitch?
The distance between pixels.
What does a lower pixel pitch indicate?
A sharper image and possibly higher resolutions.
Which LCD display type has the best color representation and viewing angle?
Twisted Nematic (TN)
What are the down sides to using LCD TN monitors
1. They have poor color reproduction.
2.They have worse viewing angles.
Which LCD monitors offer the best contrast?
Vertical Alignment (VA) panels.
What are two methods used for the backlight in LCD monitors?
1. CCFL (Cold Cathode Fluorescent Lamp)
2. LED (Light Emitting Diode)
What is the key difference between LCD and LED monitors?
LED monitors use LEDs
Types of LED backlighting
1. WLED/EL-WLED- White LEDs on one side.
2. RGB LED- Each LED can produce 3 different colors
3. OLED- electricity applied to compound
How is light spread when using a WLED/EL-WLED monitor?
With a diffuser.
What LED is the least expensive?
What LEDs are most used?
What is a benefit of RGB LED monitors
Better more accurate colors
What are the advantages of LED?
1. Display more colors more accurately
3. Less power
4. No mercury
Advantages of OLED monitors
1. No back-light
2. Displays deep black colors
3. Thinner and lighter
Disadvantages of OLED monitors
3. Organic material has limited lifecycle
What do plasma monitors use for lighting ?
Electricity is applied to gas cells, which light themselves.
Advantages of Plasma
1. Display colors more accurately than LCD.
2. Better contrast.
3. Better refresh rate and response time.
Disadvantages of Plasma
1. Consume twice as much power as LED and LCD. (Same as CRT)
2. More heat
3. Sensitive to altitude changes.
Which monitor is best?
That depends on your likes and needs.
What do CCFL lights use for power?
What do LED lights use for power?
What are advantages to using LCD VA panels?
Better color reproduction and wider viewing angles.
What are disadvantages to using LCD VA panels?
1. More expensive than Twisted Nematic (TN) displays
2. Slower response time than Twisted Nematic (TN) displays
3. Color shift produces uneven colors across the display with loss of detail in dark scenes.
Which LCD monitors have the best color reproduction quality and viewing angles of the display types, and are well sutied for graphic design?
In Plane Switching (IPS) panels.
Why are CRT monitors still used by graphic artists?
They have better color reproduction than TN monitors and are cheaper than IPS monitors.
What is an aspect ratio?
The ratio of the width and the height.
Which aspect ratio is used by normal displays?
Which aspect ratio is used by widescreen displays?
Which aspect ratio is used by high definition movies and television?
What is the difference between 720, 1080p and 1080i? Which would you choose for full HDTV support?
How can you tell the difference between a DVI-A and a DVI-D cable?
Which connectors are used for an analog video signal? Which connectors provide only a digital signal?
What is another name for a D-Sub/DB-15 connector?
What type of output does a D-Sub/DB-15/VGA connector provide?
What does DVI-A stand for?
Digital video- analog
What type of output does a DVI-A connector provide?
What does DVI-D stand for?
Digital video- Digital
What type of output does a DVI-D connector provide?
What does DVI-I stand for?
Digital video- Integrated
What type of output does a DVI-I connector provide?
Analog and Digital
What is a DMS-59 port used for?
Sends out two separate DVI signals throught the single connector
What does a Composite video cable provide?
Video only TV output
What do you connect with a composite video cable?
TV, VCR, or video camera.
What is the difference between composite and component video?
When might you see an F-type connector on a video card?
What are the advantages of dual link cables over single link cables?
Dual link allows for longer cable lengths and higher video resolution.
