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

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






21. 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.






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

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






25. ____ are tube monitors with a flatter glass tube that results in an image with less distortion around the edges.
