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






2. 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.






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






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






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






6. 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






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






8. ____ video cable and female port.






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






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






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






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






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






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

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






21. 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.






22. 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.






23. 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.






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






25. A ____ connection on a video card provides analog output and are rarely (if ever) used for computers monitors - but might be used on some HDTV systems.






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






27. 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.
