  • 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 are the most expensive type of panel - and could be difficult to find.






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






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






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






5. 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.






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

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






9. 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






10. The ____ is the number of pixels - and is expressed using two numbers: the number of horizontal rows and vertical columns.






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






12. LCD displays are very delicate and occasionally a pixel fails to display properly (called a ____).






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






14. 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.






15. Single link DVI-D connectors can support 60 Hz up to ____ x ____ resolution.






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.






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






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






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






20. 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).






21. The ____ identifies the angle at which the image can still be seen. With LCD monitors - the image will be dimmer and colors distorted when viewed from an angle. It is described with two numbers: horizontal angle and vertical angle - with a higher num






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






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






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






25. 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






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






27. ____ 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.






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






29. 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.






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






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






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






33. 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.






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






35. ____ 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.






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






37. Most manufactures have a minimum number of ____ pixels that must exist before they will consider an exchange. In addition - some place limitations on where they must be located in order to qualify.






38. 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 ____.






39. Screen size is often expressed in two different measures - the ____ screen size (also called the actual size) and the ____ viewing size that identifies the largest image size that can be displayed.






40. The ____ identifies the angle at which the image can still be seen. With LCD monitors - the image will be dimmer and colors distorted when viewed from an angle. It is described with two numbers: horizontal angle and vertical angle - with a higher num






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






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






43. The ____ connection has all of the pins present in both the DVI-A and DVI-D connections. Most video cards and many LCD monitors have this connection.






44. 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
