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






2. 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.

21. 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.






22. Like HDMI - DisplayPort can send audio signals over the ______ (if audio is supported by the video card and monitor).






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






24. A DVI-A (digital video-analog) is used for an ____________. Use a cable with a D-sub connection on one end and this connection on the other end to connect to the monitor.






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






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






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. 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.






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






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






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






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






33. If you watch HDTV content (DVD movies) on a 16:10 monitor - the display will either be stretched slightly or have black bars (areas without video content) on the top and the bottom. If you want to optimize DVD viewing from your computer - consider pu






34. 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.






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






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






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






38. Cheaper TVs and monitors at lower resolutions or using ____ (where every other line is drawn with each pass) are not capable of displaying all of the video content in full HD.






39. ____ DVI-D connectors have 3 rows of 6 pins with one additional larger horizontal pin.






40. ____ 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.
