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. ____ 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.






3. ____ video cable and female port.

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






7. S-video can easily be converted to composite video by combining the ____ and ____ channels into a single signal.






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






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

15. A DVI-A (digital video-analog) is used for an ____________. Use a cable with a D-sub connection on one end and this connection on the other end to connect to the monitor.






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






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






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






19. ____ or luminance identifies the amount of light the monitor produces (how bright it is) and is measured in candelas per square meter (cd/m2 also called a Nit) - with a higher number indicating a brighter screen.






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






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






22. 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.






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






24. 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

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






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






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