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. The LCD ____ provides the light that makes the individual pixels visible. The light itself is actually along the top - bottom - and/or sides - with a special layer that reflects the light throughout the display.

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






4. A ____ connection on a video card provides digital output. These connections are rated as either single link or dual link.






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






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

18. 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.






19. ____ 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.






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






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






22. ____ and active matrix are additional terms that are often used to describe LCD monitors. Currently - all LDC displays are these kinds of displays.






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






24. ____ panels offer the best contrast ratios of the display types - and are well suited for movies that require good contrast.






25. ____ cable and female port.






26. 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.






27. Pressing lightly on the ____ may revive the pixel.






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






29. 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.






30. 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.






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






32. There are currently two methods used for the backlight - 2) ____ backlights provide brighter screens - lower power consumption - a wider color range - greater contrast - and mercury-free construction. They use DC power - eliminating the need for an i

34. 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.






35. 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.
