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 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.






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






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. ____ 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.






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






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






7. 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.






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






9. Monitor size is typically described using a ____ measurement.






10. ____ female port.






11. 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.






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






13. 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).






14. 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






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






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






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






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






19. The ____ refers to the difference in light intensity between the brightest white and the darkest black. An example is 1000:1. A higher initial number indicates a better quality picture.






20. 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.






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






22. 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.






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






24. 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






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






26. 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.






27. Because ____ monitors have better color reproduction than TN monitors and are cheaper than IPS monitors - they are still used by many graphic artists.






28. 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






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






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






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






32. 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.






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






34. 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.






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