Interface Display

All Known Implementing Classes:
AbstractDisplay, UnixDisplay
@PublicApi @Immutable public interface Display
Display refers to the information regarding a video source and monitor identified by the EDID standard.

The getEdid() method returns the raw EDID (Extended Display Identification Data) byte array, a 128-byte (or longer) structure that monitors transmit to describe their capabilities. Use the EdidUtil class to parse this byte array into human-readable fields such as manufacturer ID, product ID, serial number, display dimensions, and supported resolutions.

Example: extracting monitor manufacturer and dimensions: 

for (Display display : hal.getDisplays()) {
    byte[] edid = display.getEdid();
    System.out.println("Manufacturer: " + EdidUtil.getManufacturerID(edid));
    System.out.println("Product ID:   " + EdidUtil.getProductID(edid));
    int hCm = EdidUtil.getHcm(edid);
    int vCm = EdidUtil.getVcm(edid);
    System.out.printf("Size: %d cm x %d cm%n", hCm, vCm);
}
