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. Pressing lightly on the ____ may revive the pixel.






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






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






4. ____ and active matrix are additional terms that are often used to describe LCD monitors. Currently - all LDC displays are these kinds of displays.

6. 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.






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






8. If you are concerned about dead pixels - review the ____ before purchasing.






9. 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.

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






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






17. The ____ is the number of pixels - and is expressed using two numbers: the number of horizontal rows and vertical columns.






18. Cheaper TVs and monitors at lower resolutions or using ____ (where every other line is drawn with each pass) are not capable of displaying all of the video content in full HD.






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

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






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






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






30. ____ on the screen can be mistaken for a dead pixel.






31. 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.






32. Single link DVI-D connectors can support 60 Hz up to ____ x ____ resolution.






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






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






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






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






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






39. Video cards and monitors with a built-in TV tuner have an ____ cable TV connector. Most video cards that provide cable TV input also include audio output. However - most of these cards do not provide analog or digital monitor output.
