We don't emulate monitor EDID ... Also the serial number for HID devices is (ab-)used to signal remote wakeup support (see commit 7b074a22dab4bdda9864b933f1bc811a3db42845). > I think with the touchscreen idea that means qemu never needs itself > to have a view of where it's displays are logically left/right/above/down > which is probably fortunate.
