3. The ____ is the distance between pixels measured in millimeters. The standard in color monitors in about .15 mm to .30 mm.






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






5. 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.






6. ____ on the screen can be mistaken for a dead pixel.






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






8. Cheaper TVs and monitors at lower resolutions or using ____ (where every other line is drawn with each pass) are not capable of displaying all of the video content in full HD.






9. The ____ contrast ratio indicates the difference that can be displayed at the same time.






10. The HDTV connector uses a ____-pin mini-din cable.

12. ____ DVI-D connectors have 3 rows of 8 pins plus the horizontal pin (often called a 25-pin - 24+1-pin - or 24-pin connector).






13. 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.






14. ____ link allows for longer cable lengths and a higher video resolution and you should choose this type of video card whenever possible.






15. ____ video cable and female port.






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

29. 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.






30. You can connect LCD monitors to a video card with a DVI-I connector with either a ____ or ____ connection.






31. ____ female port.






32. ____ or luminance identifies the amount of light the monitor produces (how bright it is) and is measured in candelas per square meter (cd/m2 also called a Nit) - with a higher number indicating a brighter screen.






33. 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.
