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






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






3. 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.






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






5. 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.

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






14. ____ 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.






15. 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.






16. ____ on the screen can be mistaken for a dead pixel.

20. ____ female port.






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






22. 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.






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

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






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






28. 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.






29. 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.






30. Composite signals combine three qualities of video into a single signal; the Y channel is for brightness or luminance and ____ and ____ channels provide ____ information.






31. 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.






32. 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 ____.
