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






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






3. 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.






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






5. 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






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






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






8. Full HD content is designed for a resolution of 1920 x 1080 using ____ (where each line on the screen is redrawn in order). Full HD support is therefore referred to as 1080p.






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






10. ____ 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.






11. 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.






12. You can connect analog CRT monitors to a video card with a...






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






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






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






16. ____ female port.






17. 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.






18. 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.






19. For manufacturers - the ____ is royalty free - whereas including an HDMI connector requires a fee for each connector used. Manufacturers such as Dell and Apple are starting to use DisplayPorts in monitors and video cards - but these are not yet used






20. ____ 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.






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






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






23. 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.






24. 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.






25. 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.






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






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






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






29. ____ 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.






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






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






32. Having a few dead ____ can be common on many displays.






33. Full HD content is designed for a resolution of 1920 x 1080 using ____ (where each line on the screen is redrawn in order). Full HD support is therefore referred to as 1080p.






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






35. ____ (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.






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






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






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






39. 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.






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






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






42. ____ 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.






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






44. Having a few dead ____ can be common on many displays.






45. ____ are tube monitors with a flatter glass tube that results in an image with less distortion around the edges.
