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.

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






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






5. 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).






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






7. ____ panels have relatively slow response times (6ms to 16ms) - and have a slight purple tint in blacks when viewed from a wide angle.






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






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






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






11. 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






12. 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.

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






15. ____ are tube monitors with a flatter glass tube that results in an image with less distortion around the edges.






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






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






18. ____ 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.






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






20. 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.






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






22. 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.






23. A DVI-A (digital video-analog) is used for an ________________. Some LCD monitors have either a D-sub or this connection.






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






25. Single link DVI-D connectors can support 60 Hz up to ____ x ____ resolution.






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






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






28. You can use a DVI-to-HDMI cable to connect the ____ output from a video card to a monitor or an HDTV device that has an HDMI connector. However - this configuration only supplies video - and not audio - to the display device.






29. 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.






30. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. WSXGA+ = ____ x ____. UXGA = 1600 x 1200 WUXGA = 1920 x 1200






31. 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
