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. ____ video cable and female port.






2. ____ and ____ are electrically equivalent - meaning that a simple pin-to-pin adapter is all that is required to connect a DVI device to an HDMI port.






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






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






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






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






7. 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.






8. A DVI-A (digital video-analog) is used for an ________________. Some LCD monitors have either a D-sub or this connection.






9. ____ link allows for longer cable lengths and a higher video resolution and you should choose this type of video card whenever possible.






10. The ____ identifies the angle at which the image can still be seen. With LCD monitors - the image will be dimmer and colors distorted when viewed from an angle. It is described with two numbers: horizontal angle and vertical angle - with a higher num






11. LCD monitors often include features for HDTV support such as an HDMI input that accepts ____________ through the HDMI port.






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






13. ____ 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.






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






15. 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.






16. 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.






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






18. 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.






19. There are currently two methods used for the backlight - 1) ____ that is currently the most common backlight source and require an inverter to provide AC power to the backlight.






20. 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






21. 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.






22. Because ____ monitors have better color reproduction than TN monitors and are cheaper than IPS monitors - they are still used by many graphic artists.






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






24. The ____ is the distance between pixels measured in millimeters. The standard in color monitors in about .15 mm to .30 mm.






25. DVI-D ____ link cable.






26. 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.






27. 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 ____.






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






29. You can only connect a digital monitor to a DVI-D connector. Connecting an analog monitor - such as a CRT monitor - is only possible by using a special ____.






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






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






32. 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.






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






34. 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.






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






36. ____ is a digital video and audio connector used for high-definition digital audio and video. Itcombines the audio and video signals onto a single cable. You can use HDMI connectors with a video card with an ____ connector. Many of these video cards
