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. ____ is drawing the screen in two passes; odd lines on the first and then the even lines on the second pass.






2. ____ 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.






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






4. Pressing lightly on the ____ may revive the pixel.






5. 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.






6. 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.






7. LCD monitors often include features for HDTV support such as support for ____ to watch copy-protected content.






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






9. 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






10. Resolutions with a W in the name are X____ resolutions with a 16:10 aspect ratio. In addition to these standard resolutions - you can also purchase monitors with the 16:9 aspect ratio used by HDTV content.

18. 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.

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






25. 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.






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

28. A ____ screen is typically desired for watching movies - or on laptops where the screen is viewed in full sunlight.






29. CRT monitors with DVI-D connectors are possible but rare. This means that the CRT monitor accepts ____ input.






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






31. Because ____ monitors have better color reproduction than TN monitors and are cheaper than IPS monitors - they are still used by many graphic artists.






32. The ____ is the distance between pixels. A lower number means a sharper image and possibly higher resolutions.






33. 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.






34. If the video card only has a DVI-D connector and you have an analog-only monitor - it is often cheaper to purchase a new ____ instead of the converter box.






35. The ____ is the number of pixels available on a display screen. Specifically - it is described by the amount of pixels horizontally across the display by the amount of pixels vertically down the display.






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






37. For manufacturers - the ____ is royalty free - whereas including an HDMI connector requires a fee for each connector used. Manufacturers such as Dell and Apple are starting to use DisplayPorts in monitors and video cards - but these are not yet used






38. The ____ is the ratio of the width and the height.
