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. The ____ connection has all of the pins present in both the DVI-A and DVI-D connections. Most video cards and many LCD monitors have this connection.






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






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






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






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






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






7. Some LCD monitors have a D-sub connection - or you might need a cable with this connection on one end and a _______ on the other end to connect to the LCD monitor.






8. ____ video cable and female port.






9. A ____ connection on a video card provides analog - video-only TV output. These video connectors are RCA connectors (typically yellow).






10. ____ panels are the most expensive type of panel - and could be difficult to find.






11. Video cards and monitors with a built-in TV tuner have an ____ cable TV connector. Most video cards that provide cable TV input also include audio output. However - most of these cards do not provide analog or digital monitor output.






12. 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.






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






14. 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.






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






16. 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.






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






18. ____ is an alternative to an HDMI connector.






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






20. 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.






21. Some LCD monitors have a D-sub connection - or you might need a cable with this connection on one end and a _______ on the other end to connect to the LCD monitor.






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






23. Resolutions with a W in the name are X____ resolutions with a 16:10 aspect ratio. In addition to these standard resolutions - you can also purchase monitors with the 16:9 aspect ratio used by HDTV content.






24. 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.






25. ____ (1280 x 720 progressive scan) and ____ (1920 x 1080 with interlacing) identify displays that do not support full HD content - with both 720p and 1080i being comparable in quality.






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






27. ____ 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.






28. 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.






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






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






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






32. 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.






33. There are ____ to identify and possibly fix dead pixels on a monitor.






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






35. 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.






36. A ____ connection on a video card provides both analog and digital output.






37. Resolutions with a W in the name are X____ resolutions with a 16:10 aspect ratio. In addition to these standard resolutions - you can also purchase monitors with the 16:9 aspect ratio used by HDTV content.






38. ____ 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.






39. 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.






40. The smaller the dot pitch - the more room there is for____ resolutions and the ____ a picture may be.






41. ____ cable and female port.
