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. 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






2. 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.






3. The HDTV connector uses a ____-pin mini-din cable.






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






5. ____ and ____ are electrically equivalent - meaning that a simple pin-to-pin adapter is all that is required to connect a DVI device to an HDMI port.






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






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






8. 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.






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






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






11. ____ video cable and female port.






12. You can only connect a digital monitor to a DVI-D connector. Connecting an analog monitor - such as a CRT monitor - is only possible by using a special ____.






13. 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).






14. 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.






15. 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.






16. You can connect analog CRT monitors to a video card with a...






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






18. DVI-D ____ link cable.






19. 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.






20. 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.






21. ____ 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.






22. Be aware that the display qualities of your monitor depend on the capabilities of both the monitor and the ____.






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






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






25. Be aware that the display qualities of your monitor depend on the capabilities of both the monitor and the ____.






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






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






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






29. S-video (separate-video - Y/C - or S-VHS) connections are present on many video cards and supply ____ - video-only TV output.






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. 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 ____.






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






33. ____ monitors use a single value for the screen size. These monitors can use the entire screen for displaying images - use a liquid crystal material and transistors to display images.






34. You can only connect a digital monitor to a DVI-D connector. Connecting an analog monitor - such as a CRT monitor - is only possible by using a special ____.






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






36. Most manufactures have started using a ____ measure of response time - which makes the response time faster than a white-to-black response time.






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






38. 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.






39. An ____ connector supplies analog - video-only TV output in three separate channels: R (red) - G (green) - and B (blue).






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






42. ____ monitors use a single value for the screen size. These monitors can use the entire screen for displaying images - use a liquid crystal material and transistors to display images.
