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.

2. Some LCD monitors have a D-sub connection - or you might need a cable with this connection on one end and a _______ on the other end to connect to the LCD monitor.






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






4. TN panels have ____ viewing angles and contrast ratios than the other display types.






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






6. 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.






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






8. ____ displays have a 4:3 aspect ratio (used in CRT displays).






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






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






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






12. ____ 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.

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






15. 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






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






17. 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.






18. ____ cable and female port.






19. You can connect LCD monitors to a video card with a DVI-I connector with either a ____ or ____ connection.






20. Composite signals combine three qualities of video into a single signal; the ____ channel is for ____ or luminance and U and V channels provide color information.

25. ____ panels are the most expensive type of panel - and could be difficult to find.






26. 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.






27. Be aware that the display qualities of your monitor depend on the capabilities of both the monitor and the ____.






28. 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.






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






30. 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.






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






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






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






34. 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.






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






36. Full HD content is designed for a resolution of 1920 x 1080 using ____ (where each line on the screen is redrawn in order). Full HD support is therefore referred to as 1080p.
