  • 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. 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.

3. 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






4. 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






5. ____ DVI-D connectors have 3 rows of 6 pins with one additional larger horizontal pin.






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

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






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






11. Having a few dead ____ can be common on many displays.






12. ____ (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.






13. Video cards and monitors with a built-in TV tuner have an ____ cable TV connector. Most video cards that provide cable TV input also include audio output. However - most of these cards do not provide analog or digital monitor output.






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. ____ video cable and female port.






16. The ____ connector is used to allow multiple video ports from a single connection.It is typically included on slimline video cards that can have only a single port. It sends out two separate DVI-I signals through the single connector.






17. 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.






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






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






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






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






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






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






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






25. Composite signals combine three qualities of video into a single signal; the ____ channel is for ____ or luminance and U and V channels provide color information.






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






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






28. ____ 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.






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






30. 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






31. 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.






32. 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.






33. ____ monitors use a single value for the screen size. These monitors can use the entire screen for displaying images - use a liquid crystal material and transistors to display images.






34. 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
