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






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






3. The ____ is the number of pixels - and is expressed using two numbers: the number of horizontal rows and vertical columns.






4. 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






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






6. If you are concerned about dead pixels - review the ____ before purchasing.






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






8. 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).






9. There are two methods of controlling the illumination of the phosphor - 1) ____ that consists of a metal screen full of holes that are aligned with each dot. The screen shields the electron beam from illuminating between dots and leaves an outline ar






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






11. Additional monitor features include built in ____ or ____ hub.

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






14. It is common for ____ monitors to support a wide number of resolutions - but LCD monitors often have a____ (optimum) display resolution.






15. ____ 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.






16. The ____ is the number of pixels - and is expressed using two numbers: the number of horizontal rows and vertical columns.






17. 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.






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






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






20. ____ 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.






21. 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.






22. If the video card only has a DVI-D connector and you have an analog-only monitor - it is often cheaper to purchase a new ____ instead of the converter box.






23. 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






24. ____ (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.






25. 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.






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






27. ____ female port.






28. Cheaper TVs and monitors at lower resolutions or using ____ (where every other line is drawn with each pass) are not capable of displaying all of the video content in full HD.






29. There are two methods of controlling the illumination of the phosphor - 1) ____ that consists of a metal screen full of holes that are aligned with each dot. The screen shields the electron beam from illuminating between dots and leaves an outline ar






30. ____ female port.






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






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






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






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






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






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






37. VA panels suffer from ____ that produces uneven colors across the display with loss of detail in dark scenes.
