2. ____ panels have the best color reproduction quality and viewing angles of the display types - and are well suited for graphic design where full and accurate color representation is required.






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






4. 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.






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

18. A DVI-A (digital video-analog) is used for an ________________. Some LCD monitors have either a D-sub or this connection.






19. Monitor size is typically described using a ____ measurement.






20. 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.






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






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

26. A ____ connection on a video card provides analog - video-only TV output. These video connectors are RCA connectors (typically yellow).






27. 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.






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

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






32. Without a built-in tuner - video input is limited to a ____ channel - and changing TV channels must be done at the ____ device before inputting into the video card.
