This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. ____ is drawing the screen in two passes; odd lines on the first and then the even lines on the second pass.






2. 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.






3. ____ 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.






4. 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.






5. You can connect an analog CRT or LCD monitor to a video card with a DVI-I connector. This requires a cable with a ____ connection on one end and a ____ connection on the other end.






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






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






8. 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.






9. DisplayPort is also an internal video interface used by ____ displays to interface with internal video cards.






10. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. WSXGA+ = ____ x ____. UXGA = 1600 x 1200 WUXGA = 1920 x 1200






11. LDC monitors use ____ panels that are the most common type used in computer monitors - especially in smaller sizes. These panels have very good response times (2ms to 5ms) - so are well-suited for games with a lot of motion.






12. ____ monitors use a single value for the screen size. These monitors can use the entire screen for displaying images - use a liquid crystal material and transistors to display images.






13. 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.






14. ____ panels have relatively slow response times (6ms to 16ms) - and have a slight purple tint in blacks when viewed from a wide angle.






15. ____ displays have a 4:3 aspect ratio (used in CRT displays).






16. The ____ is the ratio of the width and the height.






17. 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.






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






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






20. ____ panels have relatively slow response times (6ms to 16ms) - and have a slight purple tint in blacks when viewed from a wide angle.






21. A ____ connection on a video card provides both analog and digital output.






22. 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






23. 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.






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






25. 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.






26. The D-sub connector on a video card provides....






27. Green monitors are Energy Star or Green Star compliant. These monitors use less than ____ watts and reduce power consumption by ____% when in sleep or suspended mode.






28. ____ 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.






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






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






31. Single link DVI-D connectors can support 60 Hz up to ____ x ____ resolution.






32. ____ (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.






33. If you watch HDTV content (DVD movies) on a 16:10 monitor - the display will either be stretched slightly or have black bars (areas without video content) on the top and the bottom. If you want to optimize DVD viewing from your computer - consider pu






34. CRT monitors with DVI-D connectors are possible but rare. This means that the CRT monitor accepts ____ input.






35. 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.






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






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






38. If you watch HDTV content (DVD movies) on a 16:10 monitor - the display will either be stretched slightly or have black bars (areas without video content) on the top and the bottom. If you want to optimize DVD viewing from your computer - consider pu






39. 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
