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 distance between pixels. A lower number means a sharper image and possibly higher resolutions.






2. 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






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






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






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






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






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






8. It is common for ____ monitors to support a wide number of resolutions - but LCD monitors often have a____ (optimum) display resolution.






9. ____ 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.






10. Resolutions with a W in the name are X____ resolutions with a 16:10 aspect ratio. In addition to these standard resolutions - you can also purchase monitors with the 16:9 aspect ratio used by HDTV content.






11. 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.






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






13. 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.






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






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






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






18. The ____ connection has all of the pins present in both the DVI-A and DVI-D connections. Most video cards and many LCD monitors have this connection.






19. 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






20. The HDTV connector uses a ____-pin mini-din cable.






21. For manufacturers - the ____ is royalty free - whereas including an HDMI connector requires a fee for each connector used. Manufacturers such as Dell and Apple are starting to use DisplayPorts in monitors and video cards - but these are not yet used






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






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






24. 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.






25. ____ female port.






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






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






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






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






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






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






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






33. 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.






34. ____ or luminance identifies the amount of light the monitor produces (how bright it is) and is measured in candelas per square meter (cd/m2 also called a Nit) - with a higher number indicating a brighter screen.






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






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






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






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