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 smaller the dot pitch - the more room there is for____ resolutions and the ____ a picture may be.






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






3. 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






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






5. ____ 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.






6. 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.






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






8. 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.






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






10. 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.






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






12. 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.






13. S-video can easily be converted to composite video by combining the ____ and ____ channels into a single signal.






14. 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. ____ 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.






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






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

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






21. Monitor size is typically described using a ____ measurement.






22. 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.






23. 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

28. LCD monitors often include features for HDTV support such as support for ____ to watch copy-protected content.






29. 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.






30. ____ (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.






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






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






33. 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






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