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






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






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






4. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. SXGA = ____ x ____ (5:4 aspect ratio).






5. 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.






6. DVI-D ____ link cable.






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






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






9. The ____ is the distance between pixels measured in millimeters. The standard in color monitors in about .15 mm to .30 mm.






10. 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.






11. 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.






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






13. LDC monitors use ____ panels that are the most common type used in computer monitors - especially in smaller sizes. These panels have very good response times (2ms to 5ms) - so are well-suited for games with a lot of motion.






14. TN panels have poor color reproduction due to the fact that only ____-bits per color can be displayed. They mimic true 24-bit color using dithering and other techniques.






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






16. ____ is a digital video and audio connector used for high-definition digital audio and video. Itcombines the audio and video signals onto a single cable. You can use HDMI connectors with a video card with an ____ connector. Many of these video cards






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






18. 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






19. LCD monitors often include features for HDTV support such as built-in speakers and audio-out to ____ speakers. LCD monitors often include features for HDTV support such as an HDTV tuner to allow you to watch TV and change channels when the monitor is






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






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






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






23. If you are concerned about dead pixels - review the ____ before purchasing.






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






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






26. 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.






27. 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.






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. ____ 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.






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






31. 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.






32. 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.






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






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






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






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






38. 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 ____.






39. It is common for ____ monitors to support a wide number of resolutions - but LCD monitors often have a____ (optimum) display resolution.






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






41. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. SXGA = ____ x ____ (5:4 aspect ratio).






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






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






44. The magnetic field used for drawing the image on the screen can cause a buildup of magnetism on internal monitor components. This magnetic field can cause color distortions - especially around the edges. To correct this problem - use the ____ feature






45. 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.






46. 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.
