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. 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.






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






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






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






5. The ____ connector - sometimes called a VGA connector - uses a DB-15 connector with three rows of pins.






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






7. 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.






8. 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.

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






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






16. 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.

19. LCD displays are very delicate and occasionally a pixel fails to display properly (called a ____).






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






21. A ____ connection on a video card provides digital output. These connections are rated as either single link or dual link.






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






23. 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.






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






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






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






27. ____ video cable and female port.






28. Pressing lightly on the ____ may revive the pixel.






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






30. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. WSXGA+ = ____ x ____. UXGA = 1600 x 1200 WUXGA = 1920 x 1200






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

34. 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.






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






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






37. 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.






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