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






2. 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.






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






4. 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






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






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






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






8. 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.






9. 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.






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






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






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






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






14. 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.






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






16. ____ 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.






17. ____ female port.






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






19. 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.






20. 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.






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






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






23. 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.






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






25. 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.






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






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






28. An ____ connector supplies analog - video-only TV output in three separate channels: R (red) - G (green) - and B (blue).






29. The ____ indicates how quickly a pixel can go from black - to white - and back to black and is indicated in milliseconds (ms).






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






31. ____ 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.






32. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. WSXGA+ = ____ x ____. UXGA = 1600 x 1200 WUXGA = 1920 x 1200






33. ____ 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.






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






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






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






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






38. 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.






39. 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).






40. Because ____ monitors have better color reproduction than TN monitors and are cheaper than IPS monitors - they are still used by many graphic artists.






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






42. ____ 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.






43. The ____ indicates how quickly a pixel can go from black - to white - and back to black and is indicated in milliseconds (ms).






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






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






46. 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






47. 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






48. For manufacturers - the ____ is royalty free - whereas including an HDMI connector requires a fee for each connector used. Manufacturers such as Dell and Apple are starting to use DisplayPorts in monitors and video cards - but these are not yet used






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