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. 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.






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






3. ____ 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.






4. 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.






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






6. 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.






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






8. 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.






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






10. 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.






11. ____ DVI-D connectors have 3 rows of 6 pins with one additional larger horizontal pin.






12. Most manufactures have started using a ____ measure of response time - which makes the response time faster than a white-to-black response time.






13. ____ 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.






14. 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.






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






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






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






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






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






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






21. Dual link DVI-D can support 60 Hz up to ____ x ____ resolution.






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






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






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






25. You can only connect a digital monitor to a DVI-D connector. Connecting an analog monitor - such as a CRT monitor - is only possible by using a special ____.






26. 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.






27. LCD monitors often include features for HDTV support such as support for ____ to watch copy-protected content.






28. ____ monitors will typically list the monitor size along with the viewable image size which is smaller than the total screen size. Because of how the monitor is made - not all of the available screen size can actually display an image.






29. 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.






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






31. 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.






32. You can connect LCD monitors to a video card with a DVI-I connector with either a ____ or ____ connection.






33. VA panels have ____ color reproduction and wider viewing angles than TN displays - but with slower response times and a higher cost.






34. The DMS-59 uses a special cable that ____________into separate video interfaces. For example - the cable might split the signal into two DVI-I connectors - two D-sub connectors - or one DVI-I connector and one D-sub connector.






35. ____ panels have the best color reproduction quality and viewing angles of the display types - and are well suited for graphic design where full and accurate color representation is required.






36. DisplayPort does not use ______ than DVI and HDMI.






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






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






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






40. DVI-D ____ link cable.






41. You can only connect a digital monitor to a DVI-D connector. Connecting an analog monitor - such as a CRT monitor - is only possible by using a special ____.






42. S-video (separate-video - Y/C - or S-VHS) connections are present on many video cards and supply ____ - video-only TV output.






43. DisplayPort uses a different signal format than DVI or HDMI. However - it supports sending DVI or HDMI signals over the same port using a simple ____.






44. VA panels suffer from ____ that produces uneven colors across the display with loss of detail in dark scenes.






45. ____ DVI-D connectors have 3 rows of 8 pins plus the horizontal pin (often called a 25-pin - 24+1-pin - or 24-pin connector).






46. DVI-D ____ link cable.






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

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






50. You can use a DVI-to-HDMI cable to connect the ____ output from a video card to a monitor or an HDTV device that has an HDMI connector. However - this configuration only supplies video - and not audio - to the display device.
