We have everything hooked up and running but the top system tray (not sure what Mac calls this) is not showing at all but if you move the mouse up into there you can get stuff but it's just not 'showing' anything like time, date, battery or wi fi icons like you would see on a monitor. Also the bottom of the screen is not showing all of the icons properly. They are cut off at the bottom. We've tried changing from 16x9 to 4x3 and nothing works. Any ideas? Would appreciate any help. Thanks!
