I do know that Dell has released several bios updates for the hybrids  
as well, so its possible an updated bios would help, if you're not  
already running the latest.

I'm still running the original bios on mine, (1.0.4), due to dell's  
bios updater for some reason not working when I try to run it off a  
freedos/memdisk usb stick, but the reason I'm even bothering to look  
at updating is to see if the newer bios kills off the phantom lvds  
output (laptop panel) the original bios claims to have, which causes  
some interesting issues with kernel mode-setting[1]. That phantom lvds  
*could* be relevant to your case as well, not entirely sure -- a buddy  
w/a hybrid had similar-ish issues with a Samsung (iirc) HDTV. But I  
believe he at least got bios output on his TV.
