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






2. ____ (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.






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






4. ____ 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.






5. Most manufactures have started using a ____ measure of response time - which makes the response time faster than a white-to-black response time.






6. If the video card only has a DVI-D connector and you have an analog-only monitor - it is often cheaper to purchase a new ____ instead of the converter box.






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






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






9. DisplayPort does not use ______ than DVI and HDMI.






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






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






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






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






15. A DVI-A (digital video-analog) is used for an ____________. Use a cable with a D-sub connection on one end and this connection on the other end to connect to the monitor.






16. 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.






17. 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.






18. 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.






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






20. 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.






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






22. If you are concerned about dead pixels - review the ____ before purchasing.






23. 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.






24. 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






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






26. ____ 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.






27. 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






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






29. 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.






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






31. DisplayPort is also an internal video interface used by ____ displays to interface with internal video cards.






32. ____ 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.






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






34. ____ 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.






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






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






37. LCD monitors often include features for HDTV support such as support for ____ to watch copy-protected content.






38. 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.






39. If you are concerned about dead pixels - review the ____ before purchasing.






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