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






2. LCD displays are very delicate and occasionally a pixel fails to display properly (called a ____).






3. 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






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






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






6. The HDTV connector uses a ____-pin mini-din cable.






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






8. Without a built-in tuner - video input is limited to a ____ channel - and changing TV channels must be done at the ____ device before inputting into the video card.






9. LCD displays are very delicate and occasionally a pixel fails to display properly (called a ____).






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






11. ____ 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.






12. 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.






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






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






15. 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.






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






17. Composite signals combine three qualities of video into a single signal; the ____ channel is for ____ or luminance and U and V channels provide color information.






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 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.






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






21. 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).






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






23. ____ 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.






24. If the video card only has a DVI-D connector and you have an analog-only monitor - it is often cheaper to purchase a new ____ instead of the converter box.






25. 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.






26. 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






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






28. 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.






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






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






31. ____ cable and female port.






32. DVI-D ____ link cable.

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






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






37. ____ (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.






38. 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.
