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. 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.
