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 ____ 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.






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






3. For manufacturers - the ____ is royalty free - whereas including an HDMI connector requires a fee for each connector used. Manufacturers such as Dell and Apple are starting to use DisplayPorts in monitors and video cards - but these are not yet used






4. The ____ rate is the amount of time (measured in Hz) required for the CRT's electron beam to paint the screen from top to bottom. Increasing the rate reduces screen flicker.






5. As with composite and s-video - audio must be supplied to the device...






6. 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.






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






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






9. Having a few dead ____ can be common on many displays.






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






11. 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.






12. 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.






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






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






15. DisplayPort uses a digital-only signal. To connect a VGA monitor to it - you will need a special active ____ that reformats the signal for analog devices.






16. 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.






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






18. The ____ contrast ratio indicates the difference that can be displayed at the same time.






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






20. A ____ connection on a video card provides analog - video-only TV output. These video connectors are RCA connectors (typically yellow).






21. ____ 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.






22. S-video (separate-video - Y/C - or S-VHS) connections are present on many video cards and supply ____ - video-only TV output.






23. 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






24. 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.






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






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






27. Full HD content is designed for a resolution of 1920 x 1080 using ____ (where each line on the screen is redrawn in order). Full HD support is therefore referred to as 1080p.






28. 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.






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






30. Composite signals combine three qualities of video into a single signal; the Y channel is for brightness or luminance and ____ and ____ channels provide ____ information.






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






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






33. 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.






34. ____ displays have a 4:3 aspect ratio (used in CRT displays).






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






36. VA panels suffer from ____ that produces uneven colors across the display with loss of detail in dark scenes.






37. Increasingly - the difference between an LCD monitor and an HDTV is being blurred. You can purchase an HDTV that can also function as a monitor - or a monitor that can function as a TV. Resolutions used by HDTV are: ____ and ____.






38. Monitor size is typically described using a ____ measurement.






39. ____ (1280 x 720 progressive scan) and ____ (1920 x 1080 with interlacing) identify displays that do not support full HD content - with both 720p and 1080i being comparable in quality.
