Win7 computer can not display full screen how to do

        Many friends will be very interested in seeing some new features. Some friends with strong hands-on ability will even go to the upgrade function, but in actual operation, it will inevitably encounter various problems. For example, a friend recently mentioned that after upgrading the Win7 Ultimate system, I found that the computer could not be displayed in full screen. What caused this problem? The following small series will tell you in detail!
1 First, let's go back to the desktop of the computer, then find a blank space and right click, select the screen resolution in the slide down menu.
2. After that, the window shown in the following figure will pop up, which is the screen resolution setting window. We need to pull the interface to the bottom, then adjust the resolution to the highest, which is the recommended value of the system. After that, let's just click the OK button at the bottom of the window to save the settings.
3. After clicking OK, a window asking the user whether to save the display settings will pop up on the screen. Let's click on Save Changes to complete the operation.
Generally speaking, after the system is upgraded or reinstalled, the fault that the interface cannot be displayed in full screen can be solved. You may try to return to the desktop location to see if your current display is full screen.
