1.10 Compare and contrast types of display devices and their features

Which of the following resolutions has an aspect ratio of 16:9? 1,920 x 1,080 px 1,600 x 1,200 px 1,024 x 768 px 800 x 600 px

1,920 x 1,080 px Of the options listed, the 1,920 x 1,080 pixel (px) resolution is the only one that has a 16:9 aspect ratio. Each of the other three resolutions feature an aspect ratio of 4:3.

What term describes the fixed resolution for liquid crystal display (LCD) or other flat panel display devices?

Native resolution Native resolution describes the fixed resolution for LCD or other flat panel display devices. While older cathode ray tube (CRT) monitors are able to change resolution to match that of the signal being received, display devices with native resolution will only display the best quality image when the input signal and the native resolution are the same.

What should be considered the minimum refresh rate for a monitor?

60 hertz (Hz) The refresh rate is also sometimes called the frame rate. Typical refresh rates are 60 to 70 Hz, which means the display is refreshed 60 to 70 times per second. Setting the refresh rate to anything lower than 60 Hz typically results in noticeable flickering, so it is not recommended to set it below this threshold.

Which type of display device is always analog and requires a Video Graphics Array (VGA) cable to convert a digital signal to analog?

Cathode ray tube (CRT) A CRT monitor uses a vacuum tube to display images. CRT monitors are heavy and bulky, and have been almost completely superseded by LCD, organic light-emitting diode (OLED), and plasma displays. CRT displays are analog and require a video card and VGA cable to convert the digital signal to analog.

What unit is the refresh rate of a display device measured in?

Hertz (Hz) The refresh rate of a device is measured in Hz. Resolution describes the number of pixels that make up the display. Brightness is measured in lumens. Power is measured in watts.

Liquid crystal display (LCD) monitors use either Twisted Nematic (TN) or In-Plane Switching (IPS) technology. What advantage does IPS offer over NT?

IPS provides better color reproduction and better viewing angles. TN has fast response times, high brightness, less power draw, and is inexpensive to manufacture in comparison to IPS. However, IPS provides better color reproduction and better viewing angles. In the beginning, TN offered better contrast and better blacks than IPS. Newer IPS monitors have closed the gaps of these limitations.

If you notice that the screen displayed does not seem centered in relation to the physical device, what setting should you adjust?

Image position The image position setting allows you to adjust the location or size of the display in relation to the physical device. This is helpful in situations whereby you connect a display and notice that the image does not fill the screen fully or is stretched too far.

Which type of monitor uses cold cathode fluorescent lamps (CCFLs) as the backlight source?

Liquid crystal display (LCD) Of the monitors listed, LCD monitors are the only ones that use CCFLs as a backlight source. Some LCD monitors use LEDs instead of CCFLs, however.

What setting would you need to adjust if you wanted icons on your screen to appear larger, even though fewer objects would be able to fit on the screen?

Resolution Resolution is the setting that allows you to adjust the number of pixels that make up the dimensions of a display. As you increase the resolution, icons will appear smaller, but you will be able to fit more objects on the screen at once. Lowering the resolution will give you the opposite effect.

What does the contrast setting of a display device refer to?

The difference in intensity between adjacent colors in an image. The contrast setting describes the difference in intensity between adjacent colors in an image.

When multiple output devices are connected to a computer, what is the result of selecting the Extend display option on a Windows machine?

The primary monitor will show the typical desktop and the second monitor will provide extra space for separate applications. A major benefit of having a second monitor is the ability to show an application on the first display, and another application on the second display. To do this, you would select the Extend display option. This allows you to assign the display that should show the desktop, and the display that should show separate applications. The Duplicate option will result in the same output being visible on both displays. The Projector Only option will disable the primary display, and show output on only the secondary display.

What does the aspect ratio of a display device refer to?

The proportion of width to height of a display The aspect ratio refers to the ratio of width to height of a display. Specifically, it is the proportion of the number of pixels across the screen to the number of pixels down the screen. Most standard-definition square-shaped monitors use an aspect ratio of 4:3. High-definition widescreen monitors tend to excel with an aspect ratio of 16:9 or 16:10.

Which of the following is an advantage of organic light-emitting diode (OLED) displays over liquid crystal display (LCD) displays? -They are not damaged by water as easily as LCDs displays are. -They are brighter and consume less power than LCD displays. -They are much less expensive and are available in more sizes. -They are less susceptible to image burn-in after prolonged use.

They are brighter and consume less power than LCD displays. OLED displays are brighter than LCD displays, and because OLEDs do not require a back light source, they require less power than LCDs.

How do light-emitting diode (LED) backlights compare to cold cathode fluorescent lamp (CCFL) backlights?

They are lighter, cheaper, brighter, and have a longer lifespan. Compared to CCFL bulbs, LEDs are thinner, lighter, cheaper, brighter, use less power, and have a longer lifespan.

Which of the following is an advantage of plasma displays over other display types?

They provide high contrast, brightness, and vibrant colors from a wide viewing range. Plasma displays have a reputation for providing visuals with high contrast, brightness, and vibrant colors that can be viewed from a multitude of angles. For this reason, they work well in home theater setups. There are some drawbacks of plasma displays, though: They are susceptible to image burn-in from repeated, long-term use, although this is not as much of a problem as it used to be. They are much heavier than other displays due to their technology. They are only available in large sizes, typically 40" and greater. They tend to use more power and run hotter than LCD or LED displays.
