Display properties often include screen resolutions (ex. 400x300, 1600x900, 1920x1080, etc.), color (saturation, hue, gamma, brightness, contrast, etc.), the display you want to use (a desktop monitor, laptop screen, or an external display, such as a TV or projector, if you connect), and other options such as color depth (often 16-64 bit), display rotation (if you want everything to appear upside down), and refresh rate (measured in Hz)
Yes! Fool's Gold is actually called Iron Pyrite. It is cubic formed iron based crystal that is is a yellow to brass color. It is reflective giving you a "shiny" appearance. Gold on the other hand is a brighter yellow and is the same brightness whether it is in the shade or in the sun! If you shade pyrite with your hand, it will go dull. Gold will stay Yellow! I should also mention, if you hit pyrite with a hammer or another rock, it will shatter or break. Gold should just flatten out. Here is a comparison picture between Pyrite and Gold - http://www.homegrownfun.com/wp-content/uploads/smaller-gold-and-pyrite-400x300.jpg
