4. Be aware that the display qualities of your monitor depend on the capabilities of both the monitor and the ____.






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

8. The ____ connection has all of the pins present in both the DVI-A and DVI-D connections. Most video cards and many LCD monitors have this connection.






9. 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 ____.






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

12. Additional monitor features include built in ____ or ____ hub.






13. ____ 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).






14. ____ (1280 x 720 progressive scan) and ____ (1920 x 1080 with interlacing) identify displays that do not support full HD content - with both 720p and 1080i being comparable in quality.






15. 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.






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






17. 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






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






19. A ____ screen is typically desired for watching movies - or on laptops where the screen is viewed in full sunlight.

21. Full HD content is designed for a resolution of 1920 x 1080 using ____ (where each line on the screen is redrawn in order). Full HD support is therefore referred to as 1080p.






22. ____ 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.






23. 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.






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






25. The ____ rate is the amount of time (measured in Hz) required for the CRT's electron beam to paint the screen from top to bottom. Increasing the rate reduces screen flicker.






26. 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.






27. CRT monitors have a ____ aspect ratio which matches the display ration of a television set.






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






29. Dual link DVI-D can support 60 Hz up to ____ x ____ resolution.






30. 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.






31. Resolutions with a W in the name are X____ resolutions with a 16:10 aspect ratio. In addition to these standard resolutions - you can also purchase monitors with the 16:9 aspect ratio used by HDTV content.






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






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






34. There are currently two methods used for the backlight - 2) ____ backlights provide brighter screens - lower power consumption - a wider color range - greater contrast - and mercury-free construction. They use DC power - eliminating the need for an i
