Ok, how about only ioreg -n AppleBacklightDisplay -rxw0 or ioreg -n AppleDisplay -rxw0?
1st one didnt work or no response. just a new line
2nd one threw back a wall of text. heres an extract
"IOClass" = "AppleDisplay"
"CFBundleIdentifier" = "com.apple.iokit.IOGraphicsFamily"
"IOProviderClass" = "IODisplayConnect"
"IODisplayConnectFlags" = <00000000>
This is an external display, right? Because it doesn't look like an internal one. I tested maybe three or four LCD TVs connected to the HDMI port and all of them had "IODisplayConnectFlags" = <00000000>. But there's a question - since you don't have AppleBacklightDisplay in your IO register, where's your internal display?
yeh its ext display, running it in 'clamshell' mode as they call it, so i guess the internal display turns off according to normal system usage.
does this affect your edid goal? can test it later without ext display.
