Hey, sounds like you finally got there then Lyndomlim.
I watched 'My Week with Marilyn' last night on my X35/Mini3D/Darbee and it looked fantastic, such natural colours you could almost smell the autumn leaves in the garden.
I'd planed to run a fresh calibration (having another go at BT 1886 with the sensor facing the projector), but I've just been too busy enjoying it. Lamp is still as bright at 70+ hours as when I checked it at 15 hours.
I once spent a 7 hour session fighting with the custom gamma controls on my old HD350 just trying to get greyscale and gamma spot on and it still didn't look a patch on an autocal after 30 minutes, so another thanks to Tom (and Lumagen in my case) for this brilliant development.
EDIT: I will have a try with the enhanced HDMI next time I get the calibration discs/gear out, but don't have a problem with shadow detail at the moment in Superwhite, so may not show any improvement in my set up.
