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 DMS-59 uses a special cable that ____________into separate video interfaces. For example - the cable might split the signal into two DVI-I connectors - two D-sub connectors - or one DVI-I connector and one D-sub connector.






3. 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.






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

10. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. WSXGA+ = ____ x ____. UXGA = 1600 x 1200 WUXGA = 1920 x 1200






11. ____ 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.






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.

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






21. ____ 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.






22. 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.

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






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






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






27. The s-video connector is a ____-pin mini-din connector that has two separate channels - one for Y (luminance) and one for UV (color).






28. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. WSXGA+ = ____ x ____. UXGA = 1600 x 1200 WUXGA = 1920 x 1200






29. The D-sub connector on a video card provides....






30. ____ female port.






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






32. 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






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






34. 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.






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






36. 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.






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






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






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






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