2. Choosing between a 24-inch, 27-inch, or 32-inch monitor
Depending on your needs and budget, select the most suitable monitor model. Also, consider the distance between your computer screen and chair to ensure visual comfort.

- Another crucial aspect is the screen resolution. Higher resolution allows for more detailed display. For increasing screen sizes, recommended resolutions are: 24 inches (Full HD - 1920x1080p), 27 inches (QHD-2560x1440p), 32 inches (4K - 3840x2160p). With higher resolutions, smaller screens may shrink details and icons, necessitating scaling or zooming features to enlarge details to 120% - 150% for easier viewing.
