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






2. A ____ connection on a video card provides analog output and are rarely (if ever) used for computers monitors - but might be used on some HDTV systems.






3. 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

30. 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.






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






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






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