When demonstrating a digital visual system with multiple laptops, what should be confirmed?

Confirming that laptops properly display the resolution set by the EDID (Extended Display Identification Data) table is essential when demonstrating a digital visual system. The EDID table provides information from a display device to a video source regarding its supported resolutions and capabilities. If the laptops do not align with the resolutions specified by the EDID, it could lead to display issues, such as poor image quality, distortion, or complete failure to show an image.

Ensuring that the laptops can correctly interpret and render the resolutions helps to maintain a consistent visual experience across all devices during the demonstration. It is crucial in environments where multiple laptops are connected to a common display, as mismatched resolutions can degrade performance and impede the ability to showcase the system effectively to an audience.
