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






2. 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






3. 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.

5. A DVI-A (digital video-analog) is used for an ____________. Use a cable with a D-sub connection on one end and this connection on the other end to connect to the monitor.






6. Pressing lightly on the ____ may revive the pixel.






7. Green monitors are Energy Star or Green Star compliant. These monitors use less than ____ watts and reduce power consumption by ____% when in sleep or suspended mode.






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






9. 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.






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






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






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






13. 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 ____.






14. Full HD content is designed for a resolution of 1920 x 1080 using ____ (where each line on the screen is redrawn in order). Full HD support is therefore referred to as 1080p.






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






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






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






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






19. 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






20. When connecting various devices to a computer video card - you can typically find converter cables to match the interface on the video card with the interface on the device. However - these cables do not convert from ____ to ____ signaling.






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






22. 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.






23. 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.






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






25. A quicker ____ is needed when viewing moving images such as video or games. If it is too slow (above 8ms) the result are ghosting or blurred images.






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






27. There are two methods of controlling the illumination of the phosphor - 2) an ____ consists of a screen of ultra thin vertical and horizontal wires. This configuration allows more electrons through resulting in a richer color display.

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






30. 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.






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






32. 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.






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






34. Some LCD monitors have a D-sub connection - or you might need a cable with this connection on one end and a _______ on the other end to connect to the LCD monitor.






35. ____ 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.
