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






2. On a(n) ____ monitor you might be able to see two horizontal lines running across the display. These lines are the wires that are used to dynamically change the grill opening.






3. 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.






4. Most manufactures have a minimum number of ____ pixels that must exist before they will consider an exchange. In addition - some place limitations on where they must be located in order to qualify.






5. The LCD ____ provides the light that makes the individual pixels visible. The light itself is actually along the top - bottom - and/or sides - with a special layer that reflects the light throughout the display.






6. 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.






7. 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.






8. ____ (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.






9. 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






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






11. 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.






12. ____ 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.






13. ____ 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.






14. 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.






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






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






18. 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).






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






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






21. 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






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






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






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






25. 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.






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






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






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






29. 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.






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






31. A quicker ____ is needed when viewing moving images such as video or games. If it is too slow (above 8ms) the result are ghosting or blurred images.






32. 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.






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






34. 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.






35. 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 ____.






36. 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.






37. ____ 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.






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






39. ____ 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.






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






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






42. 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.






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






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






45. If you watch HDTV content (DVD movies) on a 16:10 monitor - the display will either be stretched slightly or have black bars (areas without video content) on the top and the bottom. If you want to optimize DVD viewing from your computer - consider pu






46. 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






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






48. You can connect an analog CRT or LCD monitor to a video card with a DVI-I connector. This requires a cable with a ____ connection on one end and a ____ connection on the other end.






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






50. ____ 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.
