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.
