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 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.






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






3. ____ video cable and female port.






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






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






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

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






9. ____ 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.






10. 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.






11. 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.






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

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






23. 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






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






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






26. 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.






27. 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






28. ____ 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.






29. Resolutions with a W in the name are X____ resolutions with a 16:10 aspect ratio. In addition to these standard resolutions - you can also purchase monitors with the 16:9 aspect ratio used by HDTV content.






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






31. Video cards with HDTV output typically include a conversion cable that converts the 7-pin connector into three ____ cables for connecting to an HDTV device.






32. 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).






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






34. There are currently two methods used for the backlight - 1) ____ that is currently the most common backlight source and require an inverter to provide AC power to the backlight.
