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






2. Some LCD monitors have a D-sub connection - or you might need a cable with this connection on one end and a _______ on the other end to connect to the LCD monitor.






3. A quicker ____ is needed when viewing moving images such as video or games. If it is too slow (above 8ms) the result are ghosting or blurred images.






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






5. A DVI-A (digital video-analog) is used for an ________________. Some LCD monitors have either a D-sub or this connection.






6. LCD monitors often include features for HDTV support such as an HDMI input that accepts ____________ through the HDMI port.






7. ____ 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.






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






9. Monitor size is typically described using a ____ measurement.






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. 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






12. 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.






13. 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.






14. 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.






15. The ____ refers to the difference in light intensity between the brightest white and the darkest black. An example is 1000:1. A higher initial number indicates a better quality picture.






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






17. Dual link DVI-D can support 60 Hz up to ____ x ____ resolution.






18. Because of how the ____ monitor works - portions of the display tube cannot be used for displaying the image.






19. The ____ connector is used to allow multiple video ports from a single connection.It is typically included on slimline video cards that can have only a single port. It sends out two separate DVI-I signals through the single connector.






20. 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.






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






22. 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.






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






24. 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.






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






26. VA panels suffer from ____ that produces uneven colors across the display with loss of detail in dark scenes.






27. 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.






28. A ____ connection on a video card provides analog - video-only TV output. These video connectors are RCA connectors (typically yellow).






29. 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.






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






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






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






33. CRT monitors have a ____ aspect ratio which matches the display ration of a television set.






34. TN panels have poor color reproduction due to the fact that only ____-bits per color can be displayed. They mimic true 24-bit color using dithering and other techniques.






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






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






37. 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.






38. 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.






39. The smaller the dot pitch - the more room there is for____ resolutions and the ____ a picture may be.






40. A quicker ____ is needed when viewing moving images such as video or games. If it is too slow (above 8ms) the result are ghosting or blurred images.






41. 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.






42. DisplayPort uses a different signal format than DVI or HDMI. However - it supports sending DVI or HDMI signals over the same port using a simple ____.






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






44. 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.






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






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






47. TN panels have poor color reproduction due to the fact that only ____-bits per color can be displayed. They mimic true 24-bit color using dithering and other techniques.






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






49. A ____ connection on a video card provides both analog and digital output.
