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.

3. 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






4. A ____ connection on a video card provides analog output and are rarely (if ever) used for computers monitors - but might be used on some HDTV systems.






5. The ____ contrast ratio indicates the difference that the monitor is capable of producing.






6. Screen size is often expressed in two different measures - the ____ screen size (also called the actual size) and the ____ viewing size that identifies the largest image size that can be displayed.






7. 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.






8. ____ 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).






9. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. SXGA = ____ x ____ (5:4 aspect ratio).






10. 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






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






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

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

18. 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.






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

21. The ____ contrast ratio indicates the difference that the monitor is capable of producing.






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






23. Monitor size is typically described using a ____ measurement.






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

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






29. ____ 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.






30. The ____ connection has all of the pins present in both the DVI-A and DVI-D connections. Most video cards and many LCD monitors have this connection.






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.
