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






2. 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.






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






4. The ____ is the number of pixels available on a display screen. Specifically - it is described by the amount of pixels horizontally across the display by the amount of pixels vertically down the display.






5. 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.






6. 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.






7. ____ 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).






8. 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.






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






10. 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.






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






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






13. DisplayPort does not use ______ than DVI and HDMI.






14. ____ 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.






15. ____ female port.






16. A ____ connection on a video card provides analog output and are rarely (if ever) used for computers monitors - but might be used on some HDTV systems.






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






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






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






20. 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






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






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






23. 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






24. 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






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






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

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






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






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






31. 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.






32. 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






33. 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






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






35. Because of how the ____ monitor works - portions of the display tube cannot be used for displaying the image.






36. An ____ connector supplies analog - video-only TV output in three separate channels: R (red) - G (green) - and B (blue).






37. 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.
