  • 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. 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.

8. ____ 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.






9. 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.






10. TN panels have ____ viewing angles and contrast ratios than the other display types.






11. The ____ is the number of pixels available on a display screen. Specifically - it is described by the amount of pixels horizontally across the display by the amount of pixels vertically down the display.






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






13. 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






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






15. 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






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






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






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






19. The HDTV connector uses a ____-pin mini-din cable.






20. 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.






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






22. 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






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






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






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






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






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






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






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






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






31. 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






32. On a(n) ____ monitor you might be able to see two horizontal lines running across the display. These lines are the wires that are used to dynamically change the grill opening.






33. DVI-D ____ link cable.






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