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. DVI-D ____ link cable.






2. LDC monitors use ____ panels that are the most common type used in computer monitors - especially in smaller sizes. These panels have very good response times (2ms to 5ms) - so are well-suited for games with a lot of motion.






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






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






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.






6. The magnetic field used for drawing the image on the screen can cause a buildup of magnetism on internal monitor components. This magnetic field can cause color distortions - especially around the edges. To correct this problem - use the ____ feature






7. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. WSXGA+ = ____ x ____. UXGA = 1600 x 1200 WUXGA = 1920 x 1200






8. S-video can easily be converted to composite video by combining the ____ and ____ channels into a single signal.






9. 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






10. 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.






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






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






13. Single link DVI-D connectors can support 60 Hz up to ____ x ____ resolution.






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






15. 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.






16. ____ are tube monitors with a flatter glass tube that results in an image with less distortion around the edges.






17. 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.






18. The ____ is the ratio of the width and the height.






19. 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.






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






21. ____ 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.






22. 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.






23. An ____ connector supplies analog - video-only TV output in three separate channels: R (red) - G (green) - and B (blue).






24. ____ 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.






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






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






27. A quicker ____ is needed when viewing moving images such as video or games. If it is too slow (above 8ms) the result are ghosting or blurred images.






28. LCD monitors often include features for HDTV support such as support for ____ to watch copy-protected content.






29. Use the ____ connection to connect a TV - VCR - or video camera to the video card. Audio signals must be supplied separately.






30. 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.






31. ____ is an alternative to an HDMI connector.






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






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






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






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






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






37. A ____ connection on a video card provides both analog and digital output.






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