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.

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






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






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

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






8. You can connect an analog CRT or LCD monitor to a video card with a DVI-I connector. This requires a cable with a ____ connection on one end and a ____ connection on the other end.

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






18. 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

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






22. ____ 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).






23. 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.






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

28. 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.






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

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






32. 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

34. 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






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






36. If the video card only has a DVI-D connector and you have an analog-only monitor - it is often cheaper to purchase a new ____ instead of the converter box.






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






38. ____ panels have the best color reproduction quality and viewing angles of the display types - and are well suited for graphic design where full and accurate color representation is required.
