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.

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






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






22. There are ____ to identify and possibly fix dead pixels on a monitor.






23. CRT monitors with DVI-D connectors are possible but rare. This means that the CRT monitor accepts ____ input.






24. The ____ is the number of pixels - and is expressed using two numbers: the number of horizontal rows and vertical columns.






25. 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.






26. If you are concerned about dead pixels - review the ____ before purchasing.

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






29. 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.






30. Having a few dead ____ can be common on many displays.






31. 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






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






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






34. Do not confuse video in - which can be supplied by composite - s-video - or HDTV connectors - with ____ capabilities. The built-in tuner means that the card or monitor itself has the ability to accept multi-channel input and change the display by cha






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






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






37. 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.






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