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.

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






3. Additional monitor features include built in ____ or ____ hub.

7. 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






8. You can connect an analog CRT or LCD monitor to a video card with a DVI-I connector. This requires a cable with a ____ connection on one end and a ____ connection on the other end.

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. 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.






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






20. 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.






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






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






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






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






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






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






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






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






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






30. 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.






31. 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.






32. DVI-D ____ link cable.






33. ____ 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.






34. ____ (1280 x 720 progressive scan) and ____ (1920 x 1080 with interlacing) identify displays that do not support full HD content - with both 720p and 1080i being comparable in quality.






35. 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.






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






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