Goodbye :-)

Just to let you know, I tried the latest OE6b5 (5.95.5 w/Kodi 15.1) from here... http://openelec.tv/get-openelec and the problem with no signal when using sync display to video was there. So I don't think it's unique to your builds. I'm now back to stable OE5/Kodi14.2 and that works properly on my Haswell Mac Mini.

I wish I had more time to spend on this, but I'm overwhelmed with other priorites.

EDIT: I think it's worth noting that unless you need the "Prefer VAAPI render method enabled" (presumably for HA of de-interlacing?) you can get the same quality video in the mainstream builds. On the latest stable OE build... set Kodi limited, force xrandr full with autostart.sh, TV limited. Perfect levels, contrast, and about as smooth a grey ramp as you can get. It was NOT clear at all from the introduction in post #1 that this is the case. It might save both you and some folks like me wasted time, by being more clear about who might benefit based on the content they watch. This is seemingly of no benefit to 24fps progressive content.

You cannot and this the thing you totally don't understand. But yeah - choose what you are happy with, user has choice and this is the OSS spirit we have here.

It's very possible I don't understand. I've been learning a lot about limited vs full levels lately so there might be something I'm missing still. Can you explain? I'd like to know.
