Resolution is one of the most important parameters of any projector. It determines the number of pixels that the projector can display and thus affects the detail and sharpness of the image. Common types of resolutions include Full HD (1920×1080 pixels), 4K (3840x2160 pixels), and XGA (1024×768 pixels). Higher resolutions generally provide a more detailed and sharper image, but may also require more computing power and can be more expensive.
