3. ____ 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.

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






6. 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.






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






8. There are two methods of controlling the illumination of the phosphor - 1) ____ that consists of a metal screen full of holes that are aligned with each dot. The screen shields the electron beam from illuminating between dots and leaves an outline ar

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






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






15. There are two methods of controlling the illumination of the phosphor - 1) ____ that consists of a metal screen full of holes that are aligned with each dot. The screen shields the electron beam from illuminating between dots and leaves an outline ar

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






28. There are ____ to identify and possibly fix dead pixels on a monitor.






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






30. ____ or luminance identifies the amount of light the monitor produces (how bright it is) and is measured in candelas per square meter (cd/m2 also called a Nit) - with a higher number indicating a brighter screen.






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






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






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






34. 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.






35. 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.
