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






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






3. 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.






4. Cheaper TVs and monitors at lower resolutions or using ____ (where every other line is drawn with each pass) are not capable of displaying all of the video content in full HD.






5. ____ panels offer the best contrast ratios of the display types - and are well suited for movies that require good contrast.






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






7. A ____ connection on a video card provides analog output and are rarely (if ever) used for computers monitors - but might be used on some HDTV systems.






8. DisplayPort does not use ______ than DVI and HDMI.






9. 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.






10. ____ 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.






11. ____ is an alternative to an HDMI connector.






12. ____ (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.






13. The ____ rate is the amount of time (measured in Hz) required for the CRT's electron beam to paint the screen from top to bottom. Increasing the rate reduces screen flicker.






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






15. 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.






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






17. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. SXGA = ____ x ____ (5:4 aspect ratio).






18. 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.






19. DVI-D ____ link cable.






20. The ____ connector - sometimes called a VGA connector - uses a DB-15 connector with three rows of pins.






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






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






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






24. The D-sub connector on a video card provides....






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






26. 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






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






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






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






30. Green monitors are Energy Star or Green Star compliant. These monitors use less than ____ watts and reduce power consumption by ____% when in sleep or suspended mode.






31. You can connect LCD monitors to a video card with a DVI-I connector with either a ____ or ____ connection.






32. On a(n) ____ monitor you might be able to see two horizontal lines running across the display. These lines are the wires that are used to dynamically change the grill opening.






33. ____ 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.






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






35. A DVI-A (digital video-analog) is used for an ____________. Use a cable with a D-sub connection on one end and this connection on the other end to connect to the monitor.






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






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






38. 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.






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






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






41. 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
