Comptia A +: Hardware Display Devices

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

5. Most manufactures have a minimum number of ____ pixels that must exist before they will consider an exchange. In addition - some place limitations on where they must be located in order to qualify.

7. The ____ contrast ratio indicates the difference that the monitor is capable of producing.






8. The ____ is the distance between pixels measured in millimeters. The standard in color monitors in about .15 mm to .30 mm.






9. RT monitors use an electron beam that hits phosphor dots inside of a vacuum tube. While it is possible for a CRT monitor to have a digital connection - virtually all CRT monitors connect to the video card using a ____ (also called a D-sub) connector.






10. There are currently two methods used for the backlight - 2) ____ backlights provide brighter screens - lower power consumption - a wider color range - greater contrast - and mercury-free construction. They use DC power - eliminating the need for an i






11. The ____ is the distance between pixels. A lower number means a sharper image and possibly higher resolutions.

13. The ____ indicates how quickly a pixel can go from black - to white - and back to black and is indicated in milliseconds (ms).






14. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. SXGA = ____ x ____ (5:4 aspect ratio).






15. There are two methods of controlling the illumination of the phosphor - 2) an ____ consists of a screen of ultra thin vertical and horizontal wires. This configuration allows more electrons through resulting in a richer color display.






16. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. XGA+ = ____ x ____.






17. TN panels have poor color reproduction due to the fact that only ____-bits per color can be displayed. They mimic true 24-bit color using dithering and other techniques.






18. Without a built-in tuner - video input is limited to a ____ channel - and changing TV channels must be done at the ____ device before inputting into the video card.






19. Single link DVI-D connectors can support 60 Hz up to ____ x ____ resolution.

25. The ____ is the number of pixels available on a display screen. Specifically - it is described by the amount of pixels horizontally across the display by the amount of pixels vertically down the display.






26. A ____ connection on a video card provides digital output. These connections are rated as either single link or dual link.

33. LCD monitors often include features for HDTV support such as support for ____ to watch copy-protected content.






34. There are two methods of controlling the illumination of the phosphor - 1) ____ that consists of a metal screen full of holes that are aligned with each dot. The screen shields the electron beam from illuminating between dots and leaves an outline ar






35. ____ monitors will typically list the monitor size along with the viewable image size which is smaller than the total screen size. Because of how the monitor is made - not all of the available screen size can actually display an image.
