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.

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






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

18. 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.






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






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






21. 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.






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






23. The ____ contrast ratio indicates the difference that the monitor is capable of producing.






24. ____ and active matrix are additional terms that are often used to describe LCD monitors. Currently - all LDC displays are these kinds of displays.






25. 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.






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






27. 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.






28. DisplayPort uses a different signal format than DVI or HDMI. However - it supports sending DVI or HDMI signals over the same port using a simple ____.






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






30. Screen size is often expressed in two different measures - the ____ screen size (also called the actual size) and the ____ viewing size that identifies the largest image size that can be displayed.






31. ____ 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.






32. ____ cable and female port.






33. ____ 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.






34. 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).






35. There are two methods of controlling the illumination of the phosphor - 1) ____ that consists of a metal screen full of holes that are aligned with each dot. The screen shields the electron beam from illuminating between dots and leaves an outline ar






36. DVI-D ____ link cable.






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






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






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






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