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. A DVI-A (digital video-analog) is used for an ____________. Use a cable with a D-sub connection on one end and this connection on the other end to connect to the monitor.






2. ____ 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.






3. 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






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






5. 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.






6. On a(n) ____ monitor you might be able to see two horizontal lines running across the display. These lines are the wires that are used to dynamically change the grill opening.






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






8. Use the ____ connection to connect a TV - VCR - or video camera to the video card. Audio signals must be supplied separately.






9. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. WSXGA+ = ____ x ____. UXGA = 1600 x 1200 WUXGA = 1920 x 1200






10. 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.






11. You can use a DVI-to-HDMI cable to connect the ____ output from a video card to a monitor or an HDTV device that has an HDMI connector. However - this configuration only supplies video - and not audio - to the display device.






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






13. 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.






14. 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






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






16. 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).






17. Additional monitor features include built in ____ or ____ hub.






18. 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.






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






20. VA panels suffer from ____ that produces uneven colors across the display with loss of detail in dark scenes.

28. DisplayPort uses a digital-only signal. To connect a VGA monitor to it - you will need a special active ____ that reformats the signal for analog devices.






29. A ____ connection on a video card provides both analog and digital output.






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






31. You can connect LCD monitors to a video card with a DVI-I connector with either a ____ or ____ connection.

36. 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.






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






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