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.

2. 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.






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






4. 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.






5. The s-video connector is a ____-pin mini-din connector that has two separate channels - one for Y (luminance) and one for UV (color).






6. ____ is drawing the screen in two passes; odd lines on the first and then the even lines on the second pass.






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






8. 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.






9. ____ are tube monitors with a flatter glass tube that results in an image with less distortion around the edges.






10. 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.






11. A quicker ____ is needed when viewing moving images such as video or games. If it is too slow (above 8ms) the result are ghosting or blurred images.






12. A ____ connection on a video card provides analog - video-only TV output. These video connectors are RCA connectors (typically yellow).






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






14. VA panels have ____ color reproduction and wider viewing angles than TN displays - but with slower response times and a higher cost.






15. 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).






16. 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.






17. 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






18. Resolutions with a W in the name are X____ resolutions with a 16:10 aspect ratio. In addition to these standard resolutions - you can also purchase monitors with the 16:9 aspect ratio used by HDTV content.






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






20. 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.






21. ____ panels offer the best contrast ratios of the display types - and are well suited for movies that require good contrast.






22. ____ or luminance identifies the amount of light the monitor produces (how bright it is) and is measured in candelas per square meter (cd/m2 also called a Nit) - with a higher number indicating a brighter screen.






23. 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.






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






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






27. 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.






28. DVI-D ____ link cable.






29. ____ is drawing the screen in two passes; odd lines on the first and then the even lines on the second pass.






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






31. A ____ screen is typically desired for watching movies - or on laptops where the screen is viewed in full sunlight.






32. Cheaper TVs and monitors at lower resolutions or using ____ (where every other line is drawn with each pass) are not capable of displaying all of the video content in full HD.






33. ____ or luminance identifies the amount of light the monitor produces (how bright it is) and is measured in candelas per square meter (cd/m2 also called a Nit) - with a higher number indicating a brighter screen.






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






35. If the video card only has a DVI-D connector and you have an analog-only monitor - it is often cheaper to purchase a new ____ instead of the converter box.






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

38. ____ panels offer the best contrast ratios of the display types - and are well suited for movies that require good contrast.






39. 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.






40. The ____ connector is used to allow multiple video ports from a single connection.It is typically included on slimline video cards that can have only a single port. It sends out two separate DVI-I signals through the single connector.






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