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.

23. DVI-D ____ link cable.






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






25. You can use a DVI-to-HDMI cable to connect the ____ output from a video card to a monitor or an HDTV device that has an HDMI connector. However - this configuration only supplies video - and not audio - to the display device.






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






27. 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.






28. It is common for ____ monitors to support a wide number of resolutions - but LCD monitors often have a____ (optimum) display resolution.






29. There are ____ to identify and possibly fix dead pixels on a monitor.






30. 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.






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






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






33. 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.






34. ____ cable and female port.






35. Dual link DVI-D can support 60 Hz up to ____ x ____ resolution.






36. 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.






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






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