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






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






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






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






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






6. 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






7. There are currently two methods used for the backlight - 1) ____ that is currently the most common backlight source and require an inverter to provide AC power to the backlight.






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






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






10. 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).






11. 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.






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






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






14. Single link DVI-D connectors can support 60 Hz up to ____ x ____ resolution.






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






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






17. 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.






18. 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.






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






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






21. 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






22. Single link DVI-D connectors can support 60 Hz up to ____ x ____ resolution.






23. 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).






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






25. 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.






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






27. ____ 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.






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






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






30. 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.






31. 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.






32. 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.






33. DisplayPort uses a digital-only signal. To connect a VGA monitor to it - you will need a special active ____ that reformats the signal for analog devices.






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






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






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






37. 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






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






39. When connecting various devices to a computer video card - you can typically find converter cables to match the interface on the video card with the interface on the device. However - these cables do not convert from ____ to ____ signaling.






40. 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.






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






42. The s-video connector is a ____-pin mini-din connector that has two separate channels - one for Y (luminance) and one for UV (color).






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






44. ____ 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.






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






46. 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
