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






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






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






4. The ____ is the distance between pixels. A lower number means a sharper image and possibly higher resolutions.

11. ____ panels have the best color reproduction quality and viewing angles of the display types - and are well suited for graphic design where full and accurate color representation is required.






12. ____ is drawing the screen in two passes; odd lines on the first and then the even lines on the second pass.

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






24. 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.






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






26. The smaller the dot pitch - the more room there is for____ resolutions and the ____ a picture may be.






27. 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






28. As with composite and s-video - audio must be supplied to the device...






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






30. DVI-D ____ link cable.






31. ____ 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.






32. A DVI-A (digital video-analog) is used for an ____________. Use a cable with a D-sub connection on one end and this connection on the other end to connect to the monitor.






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






34. ____ DVI-D connectors have 3 rows of 6 pins with one additional larger horizontal pin.






35. Video cards and monitors with a built-in TV tuner have an ____ cable TV connector. Most video cards that provide cable TV input also include audio output. However - most of these cards do not provide analog or digital monitor output.






36. Having a few dead ____ can be common on many displays.






37. 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.






38. The ____ identifies the angle at which the image can still be seen. With LCD monitors - the image will be dimmer and colors distorted when viewed from an angle. It is described with two numbers: horizontal angle and vertical angle - with a higher num






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
