  • 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. ____ 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.






2. The ____ connection has all of the pins present in both the DVI-A and DVI-D connections. Most video cards and many LCD monitors have this connection.






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

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






6. ____ 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.






7. 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.

9. 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.






10. 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.






11. Do not confuse video in - which can be supplied by composite - s-video - or HDTV connectors - with ____ capabilities. The built-in tuner means that the card or monitor itself has the ability to accept multi-channel input and change the display by cha






12. 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.






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. ____ 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






15. ____ 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.






16. ____ female port.






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






18. 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






19. ____ video cable and female port.






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






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






22. The DMS-59 uses a special cable that ____________into separate video interfaces. For example - the cable might split the signal into two DVI-I connectors - two D-sub connectors - or one DVI-I connector and one D-sub connector.






23. 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.






24. 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






25. 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.






26. 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






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






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






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






30. 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.






31. 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.






32. 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.






33. 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.
