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.
1. The ____ refers to the difference in light intensity between the brightest white and the darkest black. An example is 1000:1. A higher initial number indicates a better quality picture.






2. DisplayPort does not use ______ than DVI and HDMI.






3. Monitor size is typically described using a ____ measurement.






4. The magnetic field used for drawing the image on the screen can cause a buildup of magnetism on internal monitor components. This magnetic field can cause color distortions - especially around the edges. To correct this problem - use the ____ feature






5. Pressing lightly on the ____ may revive the pixel.






6. As with composite and s-video - audio must be supplied to the device...






7. ____ displays have a 4:3 aspect ratio (used in CRT displays).






8. The DMS-59 uses a special cable that ____________into separate video interfaces. For example - the cable might split the signal into two DVI-I connectors - two D-sub connectors - or one DVI-I connector and one D-sub connector.






9. ____ panels have the best color reproduction quality and viewing angles of the display types - and are well suited for graphic design where full and accurate color representation is required.






10. 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.






11. Video cards and monitors with a built-in TV tuner have an ____ cable TV connector. Most video cards that provide cable TV input also include audio output. However - most of these cards do not provide analog or digital monitor output.






12. Green monitors are Energy Star or Green Star compliant. These monitors use less than ____ watts and reduce power consumption by ____% when in sleep or suspended mode.






13. The D-sub connector on a video card provides....






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






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






16. DisplayPort is also an internal video interface used by ____ displays to interface with internal video cards.






17. ____ link allows for longer cable lengths and a higher video resolution and you should choose this type of video card whenever possible.






18. CRT monitors have a ____ aspect ratio which matches the display ration of a television set.






19. The ____ is the ratio of the width and the height.






20. Because of how the ____ monitor works - portions of the display tube cannot be used for displaying the image.






21. 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.






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






23. ____ (1280 x 720 progressive scan) and ____ (1920 x 1080 with interlacing) identify displays that do not support full HD content - with both 720p and 1080i being comparable in quality.






24. DisplayPort uses a different signal format than DVI or HDMI. However - it supports sending DVI or HDMI signals over the same port using a simple ____.






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






26. Full HD content is designed for a resolution of 1920 x 1080 using ____ (where each line on the screen is redrawn in order). Full HD support is therefore referred to as 1080p.






27. The ____ rate is the amount of time (measured in Hz) required for the CRT's electron beam to paint the screen from top to bottom. Increasing the rate reduces screen flicker.






28. The ____ contrast ratio indicates the difference that can be displayed at the same time.






29. LCD displays are very delicate and occasionally a pixel fails to display properly (called a ____).






30. A DVI-A (digital video-analog) is used for an ________________. Some LCD monitors have either a D-sub or this connection.






31. 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.






32. ____ is a digital video and audio connector used for high-definition digital audio and video. Itcombines the audio and video signals onto a single cable. You can use HDMI connectors with a video card with an ____ connector. Many of these video cards






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






34. 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






35. There are currently two methods used for the backlight - 1) ____ that is currently the most common backlight source and require an inverter to provide AC power to the backlight.






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






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






38. 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.






39. Green monitors are Energy Star or Green Star compliant. These monitors use less than ____ watts and reduce power consumption by ____% when in sleep or suspended mode.






40. ____ panels are the most expensive type of panel - and could be difficult to find.
