13. The ____ contrast ratio indicates the difference that the monitor is capable of producing.






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






15. For manufacturers - the ____ is royalty free - whereas including an HDMI connector requires a fee for each connector used. Manufacturers such as Dell and Apple are starting to use DisplayPorts in monitors and video cards - but these are not yet used






16. Most manufactures have started using a ____ measure of response time - which makes the response time faster than a white-to-black response time.






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






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






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

21. ____ are tube monitors with a flatter glass tube that results in an image with less distortion around the edges.






22. 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.

24. 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.






25. S-video can easily be converted to composite video by combining the ____ and ____ channels into a single signal.






26. 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.






27. Most manufactures have started using a ____ measure of response time - which makes the response time faster than a white-to-black response time.
