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. You can connect LCD monitors to a video card with a DVI-I connector with either a ____ or ____ connection.






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






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






4. 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.






5. LCD displays are very delicate and occasionally a pixel fails to display properly (called a ____).






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






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






8. ____ 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.






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






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






11. 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.






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






13. 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.






14. 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






15. A quicker ____ is needed when viewing moving images such as video or games. If it is too slow (above 8ms) the result are ghosting or blurred images.






16. The LCD ____ provides the light that makes the individual pixels visible. The light itself is actually along the top - bottom - and/or sides - with a special layer that reflects the light throughout the display.






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






18. A ____ connection on a video card provides analog - video-only TV output. These video connectors are RCA connectors (typically yellow).






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






20. 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.






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






22. 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.






23. ____ is a digital video and audio connector used for high-definition digital audio and video. Itcombines the audio and video signals onto a single cable. You can use HDMI connectors with a video card with an ____ connector. Many of these video cards






24. Like HDMI - DisplayPort can send audio signals over the ______ (if audio is supported by the video card and monitor).






25. S-video (separate-video - Y/C - or S-VHS) connections are present on many video cards and supply ____ - video-only TV output.






26. You can only connect a digital monitor to a DVI-D connector. Connecting an analog monitor - such as a CRT monitor - is only possible by using a special ____.






27. Dual link DVI-D can support 60 Hz up to ____ x ____ resolution.






28. 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.






29. 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






30. 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.






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






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






33. As with composite and s-video - audio must be supplied to the device...






34. 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.






35. ____ 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.






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






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






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






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






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






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






43. 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.






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