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






2. VA panels suffer from ____ that produces uneven colors across the display with loss of detail in dark scenes.






3. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. SXGA = ____ x ____ (5:4 aspect ratio).






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

6. A ____ connection on a video card provides analog output and are rarely (if ever) used for computers monitors - but might be used on some HDTV systems.






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






8. ____ 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).






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






10. LCD monitors often include features for HDTV support such as built-in speakers and audio-out to ____ speakers. LCD monitors often include features for HDTV support such as an HDTV tuner to allow you to watch TV and change channels when the monitor is






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






12. 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.






13. DVI-D ____ link cable.






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. 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.






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






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






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






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






20. The ____ refers to the difference in light intensity between the brightest white and the darkest black. An example is 1000:1. A higher initial number indicates a better quality picture.






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






22. 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.






23. Use the ____ connection to connect a TV - VCR - or video camera to the video card. Audio signals must be supplied separately.






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






25. ____ 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.






26. VA panels suffer from ____ that produces uneven colors across the display with loss of detail in dark scenes.






27. 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.






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






29. LCD monitors often include features for HDTV support such as an HDMI input that accepts ____________ through the HDMI port.






30. 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






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






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






33. 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.






34. 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.






35. 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






36. DVI-D ____ link cable.






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






38. Most manufactures have started using a ____ measure of response time - which makes the response time faster than a white-to-black response time.






39. 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.






40. 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.






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