  • 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.

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

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

8. You can use a DVI-to-HDMI cable to connect the ____ output from a video card to a monitor or an HDTV device that has an HDMI connector. However - this configuration only supplies video - and not audio - to the display device.






9. Be aware that the display qualities of your monitor depend on the capabilities of both the monitor and the ____.






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






11. DisplayPort uses a different signal format than DVI or HDMI. However - it supports sending DVI or HDMI signals over the same port using a simple ____.

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






14. ____ (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.






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






16. 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.






17. Screen size is often expressed in two different measures - the ____ screen size (also called the actual size) and the ____ viewing size that identifies the largest image size that can be displayed.






18. ____ video cable and female port.






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






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






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






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






23. 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.






24. Full HD content is designed for a resolution of 1920 x 1080 using ____ (where each line on the screen is redrawn in order). Full HD support is therefore referred to as 1080p.






25. ____ DVI-D connectors have 3 rows of 8 pins plus the horizontal pin (often called a 25-pin - 24+1-pin - or 24-pin connector).






26. 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.






27. 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.






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






29. TN panels have poor color reproduction due to the fact that only ____-bits per color can be displayed. They mimic true 24-bit color using dithering and other techniques.






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 ____ 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.






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






33. ____ 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.






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






35. 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.






36. ____ (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.






37. 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.






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






39. Some LCD monitors have a D-sub connection - or you might need a cable with this connection on one end and a _______ on the other end to connect to the LCD monitor.






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






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