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






2. S-video can easily be converted to composite video by combining the ____ and ____ channels into a single signal.






3. ____ 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.






4. 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.






5. ____ 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.






6. ____ 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.






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






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






9. 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






10. 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






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






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






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






14. 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.






15. 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.






16. 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.






17. Be aware that the display qualities of your monitor depend on the capabilities of both the monitor and the ____.






18. 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.






19. As with composite and s-video - audio must be supplied to the device...






20. 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






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






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






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






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






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






26. 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.






27. 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.






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






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






30. The ____ is the ratio of the width and the height.






31. Cheaper TVs and monitors at lower resolutions or using ____ (where every other line is drawn with each pass) are not capable of displaying all of the video content in full HD.






32. CRT monitors with DVI-D connectors are possible but rare. This means that the CRT monitor accepts ____ input.






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






34. ____ 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.






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






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






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






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