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






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






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






12. 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).






13. 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.






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

33. 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.






34. 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






35. 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.
