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.

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






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






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






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






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






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






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






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






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






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






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






14. 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.






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. ____ DVI-D connectors have 3 rows of 8 pins plus the horizontal pin (often called a 25-pin - 24+1-pin - or 24-pin connector).






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






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






19. DVI-D ____ link cable.






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






21. ____ DVI-D connectors have 3 rows of 8 pins plus the horizontal pin (often called a 25-pin - 24+1-pin - or 24-pin connector).






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






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






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






25. ____ 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.






26. Composite signals combine three qualities of video into a single signal; the ____ channel is for ____ or luminance and U and V channels provide color information.






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






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






29. 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.






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






31. 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.






32. 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.






33. 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.






34. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. SXGA = ____ x ____ (5:4 aspect ratio).






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






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






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






38. DVI-D ____ link cable.






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






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






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






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






43. 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.






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