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






2. ____ is an alternative to an HDMI connector.






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






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






5. There are currently two methods used for the backlight - 2) ____ backlights provide brighter screens - lower power consumption - a wider color range - greater contrast - and mercury-free construction. They use DC power - eliminating the need for an i






6. 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.






7. 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.






8. Increasingly - the difference between an LCD monitor and an HDTV is being blurred. You can purchase an HDTV that can also function as a monitor - or a monitor that can function as a TV. Resolutions used by HDTV are: ____ and ____.






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






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






11. Most manufactures have a minimum number of ____ pixels that must exist before they will consider an exchange. In addition - some place limitations on where they must be located in order to qualify.






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






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






14. 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






15. ____ 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.






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






17. ____ 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.






18. 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






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






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






21. 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.






22. 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.






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






24. ____ 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.






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






26. 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 ____.






27. DVI-D ____ link cable.






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






29. 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.






30. LCD displays are very delicate and occasionally a pixel fails to display properly (called a ____).






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






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






33. 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.






34. 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.






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






36. ____ DVI-D connectors have 3 rows of 8 pins plus the horizontal pin (often called a 25-pin - 24+1-pin - or 24-pin connector).






37. A ____ connection on a video card provides both analog and digital output.
