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. 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.






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






3. 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.






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

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






15. ____ 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.






16. Most manufactures have started using a ____ measure of response time - which makes the response time faster than a white-to-black response time.






17. ____ 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.






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






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






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






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






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






23. 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.






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






25. Be aware that the display qualities of your monitor depend on the capabilities of both the monitor and the ____.






26. 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).






27. ____ 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






28. 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.






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






30. 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.






31. Like HDMI - DisplayPort can send audio signals over the ______ (if audio is supported by the video card and monitor).






32. DVI-D ____ link cable.






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






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






35. ____ and active matrix are additional terms that are often used to describe LCD monitors. Currently - all LDC displays are these kinds of displays.






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. Most manufactures have started using a ____ measure of response time - which makes the response time faster than a white-to-black response time.
