If kvm comes back before monitors (likely as less electronics to reset), won't it have bad info about the monitors to give out when asked?
EDID is stored in an i2c eeprom and is powered by the video cable, so it is readable even if the display is off as as far as I understand it. Certainly VGA pin 9, pin 18 on hdmi and DVI pin 14 provide +5V power to eeprom. Displayport on the other hand does not provide eeprom power over the cable so those can only be read while on. -- Len Sorensen
