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.






2. 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.






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






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






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






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






7. ____ (1280 x 720 progressive scan) and ____ (1920 x 1080 with interlacing) identify displays that do not support full HD content - with both 720p and 1080i being comparable in quality.






8. Cheaper TVs and monitors at lower resolutions or using ____ (where every other line is drawn with each pass) are not capable of displaying all of the video content in full HD.






9. Do not confuse video in - which can be supplied by composite - s-video - or HDTV connectors - with ____ capabilities. The built-in tuner means that the card or monitor itself has the ability to accept multi-channel input and change the display by cha






10. 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.






11. LCD monitors often include features for HDTV support such as support for ____ to watch copy-protected content.






12. 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.






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






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






15. 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.






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






18. 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.






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






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






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






22. ____ (1280 x 720 progressive scan) and ____ (1920 x 1080 with interlacing) identify displays that do not support full HD content - with both 720p and 1080i being comparable in quality.






23. 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






24. The ____ contrast ratio indicates the difference that can be displayed at the same time.






25. 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.






26. ____ female port.






27. 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






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






29. The D-sub connector on a video card provides....






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






31. 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.






32. 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.






33. 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.






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






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






36. 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.






37. 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.
