 * Appendix B of the EDID 1.4 spec defines the right thing to do here.
 * If the timing given here matches a mode defined in the VESA DMT standard,
 * we _must_ use that.  If the device supports CVT modes, then we should
 * generate a CVT timing.  If both of the above fail, use GTF.
452
 *
453 454 455 456 457 458 459 460 461 462
 * There are some wrinkles here.  EDID 1.1 and 1.0 sinks can't really
 * "support" GTF, since it wasn't a standard yet; so if they ask for a
 * timing in this section that isn't defined in DMT, returning a GTF mode
 * may not actually be valid.  EDID 1.3 sinks often report support for
 * some CVT modes, but they are not required to support CVT timings for
 * modes in the standard timing descriptor, so we should _not_ treat them
 * as CVT-compliant (unless specified in an extension block I suppose).
 *
 * EDID 1.4 requires that all sink devices support both GTF and CVT timings
 * for modes in this section, but does say that CVT is preferred.
