  • 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.

17. ____ 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.






18. ____ (1280 x 720 progressive scan) and ____ (1920 x 1080 with interlacing) identify displays that do not support full HD content - with both 720p and 1080i being comparable in quality.






19. 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

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






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






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






24. ____ link allows for longer cable lengths and a higher video resolution and you should choose this type of video card whenever possible.






25. Composite signals combine three qualities of video into a single signal; the Y channel is for brightness or luminance and ____ and ____ channels provide ____ information.






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






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






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






29. RT monitors use an electron beam that hits phosphor dots inside of a vacuum tube. While it is possible for a CRT monitor to have a digital connection - virtually all CRT monitors connect to the video card using a ____ (also called a D-sub) connector.






30. Screen size is often expressed in two different measures - the ____ screen size (also called the actual size) and the ____ viewing size that identifies the largest image size that can be displayed.






31. 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






32. The ____ connection has all of the pins present in both the DVI-A and DVI-D connections. Most video cards and many LCD monitors have this connection.






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






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






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






36. 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.






37. An ____ connector supplies analog - video-only TV output in three separate channels: R (red) - G (green) - and B (blue).
