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. 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.






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






3. ____ (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.






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






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






6. 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






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






8. 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.






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






10. DVI-D ____ link cable.






11. The ____ connector - sometimes called a VGA connector - uses a DB-15 connector with three rows of pins.






12. DisplayPort uses a digital-only signal. To connect a VGA monitor to it - you will need a special active ____ that reformats the signal for analog devices.






13. 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






14. 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.






15. 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.






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






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






18. You can use a DVI-to-HDMI cable to connect the ____ output from a video card to a monitor or an HDTV device that has an HDMI connector. However - this configuration only supplies video - and not audio - to the display device.






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






20. 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.






21. 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.






22. 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.






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






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






25. 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






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






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






28. As with composite and s-video - audio must be supplied to the device...






29. 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.






30. ____ (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.






31. 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.






32. A ____ connection on a video card provides digital output. These connections are rated as either single link or dual link.






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






34. There are two methods of controlling the illumination of the phosphor - 1) ____ that consists of a metal screen full of holes that are aligned with each dot. The screen shields the electron beam from illuminating between dots and leaves an outline ar






35. 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.






36. 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.






37. 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.






38. The ____ connector - sometimes called a VGA connector - uses a DB-15 connector with three rows of pins.






39. ____ female port.






40. 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.
