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






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






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






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






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






6. 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.






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






8. Increasingly - the difference between an LCD monitor and an HDTV is being blurred. You can purchase an HDTV that can also function as a monitor - or a monitor that can function as a TV. Resolutions used by HDTV are: ____ and ____.






9. A ____ screen is typically desired for watching movies - or on laptops where the screen is viewed in full sunlight.






10. 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.






11. 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.






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






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






14. 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.






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






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






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






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






19. The ____ connector - sometimes called a VGA connector - uses a DB-15 connector with three rows of pins.






20. 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.






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






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






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






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






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






26. 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.






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






28. ____ and ____ are electrically equivalent - meaning that a simple pin-to-pin adapter is all that is required to connect a DVI device to an HDMI port.






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






30. 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.






31. ____ or luminance identifies the amount of light the monitor produces (how bright it is) and is measured in candelas per square meter (cd/m2 also called a Nit) - with a higher number indicating a brighter screen.






32. 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.






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






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






35. ____ (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.






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






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






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






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
