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.

6. ____ is an alternative to an HDMI connector.






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






8. 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.






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






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






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






12. 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






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






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






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






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

18. 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.






19. 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






20. The ____ identifies the angle at which the image can still be seen. With LCD monitors - the image will be dimmer and colors distorted when viewed from an angle. It is described with two numbers: horizontal angle and vertical angle - with a higher num






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






22. 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.






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






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






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






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






27. 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.






28. ____ on the screen can be mistaken for a dead pixel.






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






30. 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.

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






33. Additional monitor features include built in ____ or ____ hub.






34. 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.






35. ____ 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.
