Restore the recommended pixel display
1. Right-click on the desktop and click on Display Settings from the context menu.
2. In the settings page, under the customize your display option, go to Advanced display settings.
3. Under the Resolution option, make sure the pixel resolution is set to the recommended level. If not change the resolution to the recommended value from the drop-down menu.
(Also, note that any pixel resolution set to the value below 1260*768 will stretch the image causing distortion.)
4. Click on Ok to apply the setting changes.
5. Restart the system.
I Hope This Helps You Out.
