The display exposes a small block of capability data called Extended Display Identification Data, or EDID. A video source reads that data and uses it as one input when building the list of resolutions, refresh rates, color formats, and related options offered to the operating system.</p> <p>EDID is descriptive rather than a guarantee that every advertised combination will work through every connection. The source, cable, adapter, dock, receiver, link bandwidth, graphics driver, and display input can impose additional limits.</p>
