Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

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






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






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






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






5. 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






6. 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






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






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






9. DisplayPort does not use ______ than DVI and HDMI.






10. RT monitors use an electron beam that hits phosphor dots inside of a vacuum tube. While it is possible for a CRT monitor to have a digital connection - virtually all CRT monitors connect to the video card using a ____ (also called a D-sub) connector.






11. DVI-D ____ link cable.






12. 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.






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






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






15. ____ and active matrix are additional terms that are often used to describe LCD monitors. Currently - all LDC displays are these kinds of displays.






16. Because ____ monitors have better color reproduction than TN monitors and are cheaper than IPS monitors - they are still used by many graphic artists.






17. 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.






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






19. RT monitors use an electron beam that hits phosphor dots inside of a vacuum tube. While it is possible for a CRT monitor to have a digital connection - virtually all CRT monitors connect to the video card using a ____ (also called a D-sub) connector.






20. A ____ connection on a video card provides digital output. These connections are rated as either single link or dual link.






21. 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.






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






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






24. ____ panels are the most expensive type of panel - and could be difficult to find.






25. Pressing lightly on the ____ may revive the pixel.






26. Because of how the ____ monitor works - portions of the display tube cannot be used for displaying the image.






27. 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.






28. 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.






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






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






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






32. 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






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






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






35. ____ 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.






36. A DVI-A (digital video-analog) is used for an ________________. Some LCD monitors have either a D-sub or this connection.






37. You can connect analog CRT monitors to a video card with a...






38. ____ female port.






39. The s-video connector is a ____-pin mini-din connector that has two separate channels - one for Y (luminance) and one for UV (color).






40. 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






41. 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.
