  • 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. 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.

4. ____ 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.






5. There are currently two methods used for the backlight - 2) ____ backlights provide brighter screens - lower power consumption - a wider color range - greater contrast - and mercury-free construction. They use DC power - eliminating the need for an i






6. 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.

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






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






20. TN panels have poor color reproduction due to the fact that only ____-bits per color can be displayed. They mimic true 24-bit color using dithering and other techniques.






21. 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.






22. Additional monitor features include built in ____ or ____ hub.






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






24. Without a built-in tuner - video input is limited to a ____ channel - and changing TV channels must be done at the ____ device before inputting into the video card.






25. ____ 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.






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






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






28. DVI-D ____ link cable.






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

31. Some LCD monitors have a D-sub connection - or you might need a cable with this connection on one end and a _______ on the other end to connect to the LCD monitor.






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






33. 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.






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






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






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






37. ____ 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.






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






39. 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.
