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. 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.






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






3. 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 ____.






4. ____ monitors will typically list the monitor size along with the viewable image size which is smaller than the total screen size. Because of how the monitor is made - not all of the available screen size can actually display an image.






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






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






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






8. ____ 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.






9. ____ 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.






10. The HDTV connector uses a ____-pin mini-din cable.






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

14. An ____ connector supplies analog - video-only TV output in three separate channels: R (red) - G (green) - and B (blue).






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






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






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






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






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






22. 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.






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






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






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

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






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






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






31. ____ (1280 x 720 progressive scan) and ____ (1920 x 1080 with interlacing) identify displays that do not support full HD content - with both 720p and 1080i being comparable in quality.






32. VA panels suffer from ____ that produces uneven colors across the display with loss of detail in dark scenes.






33. 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






34. 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.






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






36. ____ 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.






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






38. 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






39. 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.






40. 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.






41. 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.
