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. 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






2. 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.






3. DisplayPort is also an internal video interface used by ____ displays to interface with internal video cards.

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






7. 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






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






9. 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 ____.






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






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






12. 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).






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






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






15. 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






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






17. Green monitors are Energy Star or Green Star compliant. These monitors use less than ____ watts and reduce power consumption by ____% when in sleep or suspended mode.






18. 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.






19. 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.






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






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






22. 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






23. There are currently two methods used for the backlight - 2) ____ backlights provide brighter screens - lower power consumption - a wider color range - greater contrast - and mercury-free construction. They use DC power - eliminating the need for an i






24. 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.






25. 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.






26. The D-sub connector on a video card provides....






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






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






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






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






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






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






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






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






35. 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.






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






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






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






39. There are currently two methods used for the backlight - 2) ____ backlights provide brighter screens - lower power consumption - a wider color range - greater contrast - and mercury-free construction. They use DC power - eliminating the need for an i






40. 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






41. 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.






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