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






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






3. 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






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






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






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






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






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






9. ____ monitors use a single value for the screen size. These monitors can use the entire screen for displaying images - use a liquid crystal material and transistors to display images.






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






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






12. ____ female port.






13. ____ 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.






14. 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.






15. 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.






16. 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.






17. 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.






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






19. ____ 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.






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






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






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






23. 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






24. You can connect analog CRT monitors to a video card with a...






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






27. 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.






28. DisplayPort uses a different signal format than DVI or HDMI. However - it supports sending DVI or HDMI signals over the same port using a simple ____.






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






30. Video cards and monitors with a built-in TV tuner have an ____ cable TV connector. Most video cards that provide cable TV input also include audio output. However - most of these cards do not provide analog or digital monitor output.






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






32. ____ monitors use a single value for the screen size. These monitors can use the entire screen for displaying images - use a liquid crystal material and transistors to display images.






33. ____ 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).






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






35. ____ 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.






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






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






38. 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






39. 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.






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






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






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






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






44. 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

46. A ____ screen is typically desired for watching movies - or on laptops where the screen is viewed in full sunlight.






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






48. 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.






49. A ____ connection on a video card provides digital output. These connections are rated as either single link or dual link.
