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






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






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






4. ____ 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).






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






6. DVI-D ____ link cable.






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






8. 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






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






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






11. 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.






12. 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.






13. Use the ____ connection to connect a TV - VCR - or video camera to the video card. Audio signals must be supplied separately.

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






20. A ____ connection on a video card provides analog - video-only TV output. These video connectors are RCA connectors (typically yellow).






21. 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.






22. 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.






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

25. 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.






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






27. Dual link DVI-D can support 60 Hz up to ____ x ____ resolution.






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






29. ____ 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).






30. 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.






31. ____ 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.






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






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






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






36. ____ monitors will typically list the monitor size along with the viewable image size which is smaller than the total screen size. Because of how the monitor is made - not all of the available screen size can actually display an image.






37. ____ (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.
