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 ____ connection on a video card provides both analog and digital output.

24. 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.






25. Most manufactures have a minimum number of ____ pixels that must exist before they will consider an exchange. In addition - some place limitations on where they must be located in order to qualify.






26. ____ 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.






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






28. 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.






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






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






31. 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






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. 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.
