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. 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.






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






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






4. ____ displays have a 4:3 aspect ratio (used in CRT displays).






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






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






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






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






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






10. S-video can easily be converted to composite video by combining the ____ and ____ channels into a single signal.






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






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






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






14. 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






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






16. 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.






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






18. ____ 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.






19. ____ is an alternative to an HDMI connector.






20. 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






21. 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.






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






23. DVI-D ____ link cable.






24. ____ female port.






25. 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.






26. Dual link DVI-D can support 60 Hz up to ____ x ____ resolution.






27. 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.






28. CRT monitors have a ____ aspect ratio which matches the display ration of a television set.






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






30. You can connect an analog CRT or LCD monitor to a video card with a DVI-I connector. This requires a cable with a ____ connection on one end and a ____ connection on the other end.






31. 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.






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






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






34. 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.






35. 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.
