When installing a new operating system or after installing system updates, your display may appear too large for the screen. This can also occur if you purchase a new monitor, especially if you go from regular to widescreen or vice versa. No matter the reason, having a display that's too large for the screen can be extremely frustrating. Luckily, the problem can be fixed with a few display-settings changes. These fixes can also be applied if the display appears to be too small.
Right-click anywhere on an open part of the desktop.
Click "Properties" and go to "Settings."
Choose your display from the drop-down menu. Click "Apply." If this doesn't solve the problem, continue to Step 4.
Adjust the screen resolution up or down. A higher resolution will solve the big-screen problem. Click "Apply." You may need to repeat this step if the screen still appears too large.
If you've purchased a new monitor, try using any software that came with the monitor to get the best display settings.
Don't adjust the resolution too high, or the screen will appear too small too read.
