To adjust a computer screen display, navigate to the operating system's display settings. For Windows, right-click the desktop, select "Display Settings," and modify resolution, scaling, or orientation. For macOS, go to "System Preferences" > "Display" and adjust preferences. Third-party tools like NVIDIA Control Panel (for GPUs) or f.lux can further optimize color profiles or brightness.

Proper screen display configuration enhances productivity and reduces eye strain. A 2022 study by the University of California, San Diego, found that users operating at incorrect scaling levels (e.g., 125% on Windows) experienced a 15-20% drop in task efficiency due to distorted text and interface elements. The World Health Organization (WHO) recommends adjusting screen brightness to match ambient light to minimize eye strain, with 50-70 cd/m² being optimal. Additionally, a 2021 report by Statista noted that 68% of remote workers reported improved focus after optimizing their display settings, underscoring the link between ergonomic configurations and work performance. Incorrect settings can also lead to hardware misuse; for instance, a 2023 IEEE study linked improper orientation (e.g., portrait mode on laptops) to a 22% increase in neck and shoulder discomfort among office workers. By aligning display parameters with individual needs and environmental conditions, users can achieve both comfort and efficiency gains.
