Comptia A +: Hardware Display Devices

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






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






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






4. 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.






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






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






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






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






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






10. ____ 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






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






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






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






14. ____ 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.






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






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






17. ____ 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.






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






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






20. If you watch HDTV content (DVD movies) on a 16:10 monitor - the display will either be stretched slightly or have black bars (areas without video content) on the top and the bottom. If you want to optimize DVD viewing from your computer - consider pu






21. The ____ connection has all of the pins present in both the DVI-A and DVI-D connections. Most video cards and many LCD monitors have this connection.






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






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






24. Pressing lightly on the ____ may revive the pixel.






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






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






27. If you watch HDTV content (DVD movies) on a 16:10 monitor - the display will either be stretched slightly or have black bars (areas without video content) on the top and the bottom. If you want to optimize DVD viewing from your computer - consider pu






28. DisplayPort is also an internal video interface used by ____ displays to interface with internal video cards.






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






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






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






32. ____ DVI-D connectors have 3 rows of 8 pins plus the horizontal pin (often called a 25-pin - 24+1-pin - or 24-pin connector).






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






34. 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






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






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






37. 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.
