  • 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.

22. The LCD ____ provides the light that makes the individual pixels visible. The light itself is actually along the top - bottom - and/or sides - with a special layer that reflects the light throughout the display.






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






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






25. LCD monitors often include features for HDTV support such as built-in speakers and audio-out to ____ speakers. LCD monitors often include features for HDTV support such as an HDTV tuner to allow you to watch TV and change channels when the monitor is






26. Without a built-in tuner - video input is limited to a ____ channel - and changing TV channels must be done at the ____ device before inputting into the video card.

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






34. ____ 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.






35. 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.






36. ____ panels have relatively slow response times (6ms to 16ms) - and have a slight purple tint in blacks when viewed from a wide angle.
