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. ____ 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.






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






3. 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.






4. 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.






5. The ____ identifies the angle at which the image can still be seen. With LCD monitors - the image will be dimmer and colors distorted when viewed from an angle. It is described with two numbers: horizontal angle and vertical angle - with a higher num






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






7. ____ 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






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






9. ____ DVI-D connectors have 3 rows of 8 pins plus the horizontal pin (often called a 25-pin - 24+1-pin - or 24-pin connector).






10. 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.






11. 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.






12. Resolutions with a W in the name are X____ resolutions with a 16:10 aspect ratio. In addition to these standard resolutions - you can also purchase monitors with the 16:9 aspect ratio used by HDTV content.






13. 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.






14. ____ 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.






15. 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.






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






17. 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.






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






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






20. Video cards with HDTV output typically include a conversion cable that converts the 7-pin connector into three ____ cables for connecting to an HDTV device.






21. A ____ connection on a video card provides analog - video-only TV output. These video connectors are RCA connectors (typically yellow).






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






23. A DVI-A (digital video-analog) is used for an ________________. Some LCD monitors have either a D-sub or this connection.






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






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






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






27. DVI-D ____ link cable.






28. Like HDMI - DisplayPort can send audio signals over the ______ (if audio is supported by the video card and monitor).






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






30. 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).






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






32. 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.






33. LCD monitors often include features for HDTV support such as an HDMI input that accepts ____________ through the HDMI port.






34. Video cards and monitors with a built-in TV tuner have an ____ cable TV connector. Most video cards that provide cable TV input also include audio output. However - most of these cards do not provide analog or digital monitor output.






35. 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.






36. 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.






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






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






39. The ____ connector is used to allow multiple video ports from a single connection.It is typically included on slimline video cards that can have only a single port. It sends out two separate DVI-I signals through the single connector.






40. ____ 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.






41. 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.






42. 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).
