Adjust down resolutionSee is outside monitor, or that LED display, screen, that is absolutely can realize full screen, and if it is LED display, can be adjusted through the LED display software, you can display the proportion
Not set, the resolution of the notebook is too low, and the resolution of the projector is high, it will not be full screen, display driver re install once try, and if not, it is necessary to change the graphics card
On the desktop, right-click --AMD Catalyst control center--, my digital panel panel - Zoom option (number of flat panel) - on the right, the scanned pointer draws to the right for scanning!
An external display can be full screen unless the hardware does not support it.Reason：Due to external display and notebook or desktop display resolution may be different, in the computer connected with the second display default settings for the copy case, window will be displayed in the display resolution resolution is low, resulting in relatively high screen appear on the black side.Solution steps:Change the default copy in the windows projection settings to extensionsExternal display is equivalent to the computer screen, you need to set the two screen display; hold down the win+p key (the key is the windows logo and the letters on the keyboard p key), will set out the projection display. Generally, the default is replication (two screens are exactly the same resolution and display content). For full screen, you can choose extensions (two screens with different resolutions and different displays).2 to determine the relative position of two screen, set the main screen, the mouse can pass to determine which sideExpanded into the mouse on the main screen, can also be on the second screen. The order of the screen can be set up in the video card driver, or in the window resolution which is the main screen, which is the second screen, and their relative position. (relative location determines which side of the mouse can go through to the second screen).
