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. An ____ connector supplies analog - video-only TV output in three separate channels: R (red) - G (green) - and B (blue).






2. 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.






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






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






5. 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.






6. DVI-D ____ link cable.






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






8. 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.






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






10. 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






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






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






14. ____ and ____ are electrically equivalent - meaning that a simple pin-to-pin adapter is all that is required to connect a DVI device to an HDMI port.






15. The magnetic field used for drawing the image on the screen can cause a buildup of magnetism on internal monitor components. This magnetic field can cause color distortions - especially around the edges. To correct this problem - use the ____ feature






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






17. You can connect analog CRT monitors to a video card with a...






18. 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.






19. TN panels have ____ viewing angles and contrast ratios than the other display types.






20. 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. Be aware that the display qualities of your monitor depend on the capabilities of both the monitor and the ____.






22. CRT monitors with DVI-D connectors are possible but rare. This means that the CRT monitor accepts ____ input.






23. There are ____ to identify and possibly fix dead pixels on a monitor.






24. The ____ is the distance between pixels measured in millimeters. The standard in color monitors in about .15 mm to .30 mm.






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






26. The ____ rate is the amount of time (measured in Hz) required for the CRT's electron beam to paint the screen from top to bottom. Increasing the rate reduces screen flicker.






27. Video cards with HDTV output typically include a conversion cable that converts the 7-pin connector into three ____ cables for connecting to an HDTV device.






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






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






30. On a(n) ____ monitor you might be able to see two horizontal lines running across the display. These lines are the wires that are used to dynamically change the grill opening.






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






32. Composite signals combine three qualities of video into a single signal; the ____ channel is for ____ or luminance and U and V channels provide color information.






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






34. The LCD ____ provides the light that makes the individual pixels visible. The light itself is actually along the top - bottom - and/or sides - with a special layer that reflects the light throughout the display.






35. Be aware that the display qualities of your monitor depend on the capabilities of both the monitor and the ____.






36. 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






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






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






39. You can only connect a digital monitor to a DVI-D connector. Connecting an analog monitor - such as a CRT monitor - is only possible by using a special ____.






40. A DVI-A (digital video-analog) is used for an ________________. Some LCD monitors have either a D-sub or this connection.






41. 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.
