3. If you are concerned about dead pixels - review the ____ before purchasing.

5. 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.






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






7. A DVI-A (digital video-analog) is used for an ____________. Use a cable with a D-sub connection on one end and this connection on the other end to connect to the monitor.

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






21. ____ monitors will typically list the monitor size along with the viewable image size which is smaller than the total screen size. Because of how the monitor is made - not all of the available screen size can actually display an image.






22. You can only connect a digital monitor to a DVI-D connector. Connecting an analog monitor - such as a CRT monitor - is only possible by using a special ____.

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






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






29. ____ is a digital video and audio connector used for high-definition digital audio and video. Itcombines the audio and video signals onto a single cable. You can use HDMI connectors with a video card with an ____ connector. Many of these video cards






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






31. As with composite and s-video - audio must be supplied to the device...






32. 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.






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






34. DVI-D ____ link cable.






35. The magnetic field used for drawing the image on the screen can cause a buildup of magnetism on internal monitor components. This magnetic field can cause color distortions - especially around the edges. To correct this problem - use the ____ feature






36. 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






37. An ____ connector supplies analog - video-only TV output in three separate channels: R (red) - G (green) - and B (blue).






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






39. ____ is an alternative to an HDMI connector.






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