6. ____ panels offer the best contrast ratios of the display types - and are well suited for movies that require good contrast.






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






8. When connecting various devices to a computer video card - you can typically find converter cables to match the interface on the video card with the interface on the device. However - these cables do not convert from ____ to ____ signaling.

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






27. A ____ connection on a video card provides digital output. These connections are rated as either single link or dual link.






28. 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.






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

31. There are currently two methods used for the backlight - 1) ____ that is currently the most common backlight source and require an inverter to provide AC power to the backlight.






32. If the video card only has a DVI-D connector and you have an analog-only monitor - it is often cheaper to purchase a new ____ instead of the converter box.
