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






2. 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.






3. 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).






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






5. ____ cable and female port.






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






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. 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.






9. ____ 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).






10. The ____ refers to the difference in light intensity between the brightest white and the darkest black. An example is 1000:1. A higher initial number indicates a better quality picture.






11. 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.






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






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






14. 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.






15. 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).






16. DVI-D ____ link cable.






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






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






19. LDC monitors use ____ panels that are the most common type used in computer monitors - especially in smaller sizes. These panels have very good response times (2ms to 5ms) - so are well-suited for games with a lot of motion.






20. 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.






21. It is common for ____ monitors to support a wide number of resolutions - but LCD monitors often have a____ (optimum) display resolution.






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






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. 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.






25. Like HDMI - DisplayPort can send audio signals over the ______ (if audio is supported by the video card and monitor).






26. Increasingly - the difference between an LCD monitor and an HDTV is being blurred. You can purchase an HDTV that can also function as a monitor - or a monitor that can function as a TV. Resolutions used by HDTV are: ____ and ____.






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






28. DisplayPort uses a digital-only signal. To connect a VGA monitor to it - you will need a special active ____ that reformats the signal for analog devices.






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






30. 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






31. Because of how the ____ monitor works - portions of the display tube cannot be used for displaying the image.






32. Composite signals combine three qualities of video into a single signal; the Y channel is for brightness or luminance and ____ and ____ channels provide ____ information.






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






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






35. 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.






36. 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.






37. It is common for ____ monitors to support a wide number of resolutions - but LCD monitors often have a____ (optimum) display resolution.






38. ____ and ____ are electrically equivalent - meaning that a simple pin-to-pin adapter is all that is required to connect a DVI device to an HDMI port.






39. S-video (separate-video - Y/C - or S-VHS) connections are present on many video cards and supply ____ - video-only TV output.
