  • 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.

2. DVI-D ____ link cable.






3. ____ monitors will typically list the monitor size along with the viewable image size which is smaller than the total screen size. Because of how the monitor is made - not all of the available screen size can actually display an image.






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






5. ____ 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.






6. 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.






7. 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.






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






9. Increasingly - the difference between an LCD monitor and an HDTV is being blurred. You can purchase an HDTV that can also function as a monitor - or a monitor that can function as a TV. Resolutions used by HDTV are: ____ and ____.






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






11. If you are concerned about dead pixels - review the ____ before purchasing.






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






13. It is common for ____ monitors to support a wide number of resolutions - but LCD monitors often have a____ (optimum) display resolution.






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






15. 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.






16. S-video can easily be converted to composite video by combining the ____ and ____ channels into a single signal.






17. 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.






18. 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.






19. 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.






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






21. ____ DVI-D connectors have 3 rows of 6 pins with one additional larger horizontal pin.






22. There are currently two methods used for the backlight - 2) ____ backlights provide brighter screens - lower power consumption - a wider color range - greater contrast - and mercury-free construction. They use DC power - eliminating the need for an i






23. If you are concerned about dead pixels - review the ____ before purchasing.






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






25. LDC monitors use ____ panels that are the most common type used in computer monitors - especially in smaller sizes. These panels have very good response times (2ms to 5ms) - so are well-suited for games with a lot of motion.






26. 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.






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






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






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






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






31. 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.






32. 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.






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






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 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.






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






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






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. 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.






40. 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.






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






42. Video cards with HDTV output typically include a conversion cable that converts the 7-pin connector into three ____ cables for connecting to an HDTV device.






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






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