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 ____ 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.






2. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. SXGA = ____ x ____ (5:4 aspect ratio).






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






4. ____ panels offer the best contrast ratios of the display types - and are well suited for movies that require good contrast.






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






6. 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.






7. 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.






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

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






22. 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






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

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






29. 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






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