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. ____ and active matrix are additional terms that are often used to describe LCD monitors. Currently - all LDC displays are these kinds of displays.






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






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






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






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






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






8. If you watch HDTV content (DVD movies) on a 16:10 monitor - the display will either be stretched slightly or have black bars (areas without video content) on the top and the bottom. If you want to optimize DVD viewing from your computer - consider pu






9. 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.






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






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






12. ____ link allows for longer cable lengths and a higher video resolution and you should choose this type of video card whenever possible.






13. 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






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






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

17. 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.






18. 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.






19. ____ and active matrix are additional terms that are often used to describe LCD monitors. Currently - all LDC displays are these kinds of displays.






20. Full HD content is designed for a resolution of 1920 x 1080 using ____ (where each line on the screen is redrawn in order). Full HD support is therefore referred to as 1080p.






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






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






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






24. Like HDMI - DisplayPort can send audio signals over the ______ (if audio is supported by the video card and monitor).






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






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






27. There are currently two methods used for the backlight - 1) ____ that is currently the most common backlight source and require an inverter to provide AC power to the backlight.






28. ____ female port.






29. 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.






30. 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






31. Use the ____ connection to connect a TV - VCR - or video camera to the video card. Audio signals must be supplied separately.






32. ____ displays have a 4:3 aspect ratio (used in CRT displays).






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






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






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






36. Composite signals combine three qualities of video into a single signal; the ____ channel is for ____ or luminance and U and V channels provide color information.






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