  • 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.

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






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






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






5. The ____ connector is used to allow multiple video ports from a single connection.It is typically included on slimline video cards that can have only a single port. It sends out two separate DVI-I signals through the single connector.






6. 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.






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






8. 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.

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






14. TN panels have poor color reproduction due to the fact that only ____-bits per color can be displayed. They mimic true 24-bit color using dithering and other techniques.






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






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






17. ____ 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.






18. 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.






19. 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.






20. 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.

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






23. 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.






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






25. ____ 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.






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






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






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






29. 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.






30. There are ____ to identify and possibly fix dead pixels on a monitor.






31. 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.






32. DVI-D ____ link cable.






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






35. LCD monitors often include features for HDTV support such as built-in speakers and audio-out to ____ speakers. LCD monitors often include features for HDTV support such as an HDTV tuner to allow you to watch TV and change channels when the monitor is
