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






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






3. 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.






4. 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.






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

13. 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.






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. You can connect an analog CRT or LCD monitor to a video card with a DVI-I connector. This requires a cable with a ____ connection on one end and a ____ connection on the other end.






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






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






18. 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.






19. Do not confuse video in - which can be supplied by composite - s-video - or HDTV connectors - with ____ capabilities. The built-in tuner means that the card or monitor itself has the ability to accept multi-channel input and change the display by cha






20. 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.






21. 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.






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






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






24. ____ panels offer the best contrast ratios of the display types - and are well suited for movies that require good contrast.






25. 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.






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






27. When connecting various devices to a computer video card - you can typically find converter cables to match the interface on the video card with the interface on the device. However - these cables do not convert from ____ to ____ signaling.






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






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






30. Green monitors are Energy Star or Green Star compliant. These monitors use less than ____ watts and reduce power consumption by ____% when in sleep or suspended mode.






31. 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






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






33. 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 ____.






34. Video cards with HDTV output typically include a conversion cable that converts the 7-pin connector into three ____ cables for connecting to an HDTV device.






35. 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 ____.






36. ____ (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.
