Often, when you install a new graphics card or a new monitor, the screen resolution is decreased automatically by the system, leading to the text and images appearing larger. Generally, installing the new monitor or graphic card driver fixes the issue.  The higher the screen resolution is, the more detailed and sharper the image quality. Further, the type of pixel density also remains an important part of image quality. The pixel resolution can be changed both manually and automatically. For Full HD monitors, the native resolution is 1920 x 1080. However, ultra-wide monitors have higher resolutions. You require checking the native resolution of your monitor, and after updating the graphic card driver, you can change the resolution of the screen from the Control Panel to your monitor's native resolution. That will resolve to look smaller and sharper.
