  • 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.

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






13. ____ 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.






14. 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.

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






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.

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






26. ____ 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.






27. LCD monitors often include features for HDTV support such as an HDMI input that accepts ____________ through the HDMI port.

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






31. 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






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






33. TN panels have ____ viewing angles and contrast ratios than the other display types.






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