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. 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.






4. You can connect analog CRT monitors to a video card with a...






5. 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.






6. 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.






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






8. Resolutions with a W in the name are X____ resolutions with a 16:10 aspect ratio. In addition to these standard resolutions - you can also purchase monitors with the 16:9 aspect ratio used by HDTV content.






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






10. DisplayPort uses a different signal format than DVI or HDMI. However - it supports sending DVI or HDMI signals over the same port using a simple ____.






11. A quicker ____ is needed when viewing moving images such as video or games. If it is too slow (above 8ms) the result are ghosting or blurred images.






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






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






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






15. As with composite and s-video - audio must be supplied to the device...






16. 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.






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






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






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






20. Video cards and monitors with a built-in TV tuner have an ____ cable TV connector. Most video cards that provide cable TV input also include audio output. However - most of these cards do not provide analog or digital monitor output.






21. ____ 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).






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






24. A ____ screen is typically desired for watching movies - or on laptops where the screen is viewed in full sunlight.






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






26. ____ 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.






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






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






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






30. Having a few dead ____ can be common on many displays.






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






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






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






35. 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.






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






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






38. A ____ connection on a video card provides analog output and are rarely (if ever) used for computers monitors - but might be used on some HDTV systems.






39. ____ 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).
