8. 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






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

11. ____ panels offer the best contrast ratios of the display types - and are well suited for movies that require good contrast.






12. The LCD ____ provides the light that makes the individual pixels visible. The light itself is actually along the top - bottom - and/or sides - with a special layer that reflects the light throughout the display.






13. 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






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. 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.

17. 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.






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






19. 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






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






21. DVI-D ____ link cable.






22. ____ panels have relatively slow response times (6ms to 16ms) - and have a slight purple tint in blacks when viewed from a wide angle.






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






24. 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.






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






26. 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.






27. If you are concerned about dead pixels - review the ____ before purchasing.






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






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






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

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






36. 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.
