I am running the 0137 BIOS that you linked to
I purchased a new set of 1.2 cables: http://www.amazon.com/gp/product/B003TSTDHQ/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I observed the same behavior: I can see the NUC splash screen, can enter the Intel Visual BIOS but as soon as it passes off to Windows, the signal is lost
This is the only TV I have that has a DisplayPort [reason for its purchase]
Any thoughts here? I love the NUC form factor, support... not so much
I am not from Intel and I don't yet have that exact NUC (it is on order) but I have tried DisplayPort (on an ASUS monitor - not a TV) and can probably try again. I am not sure but I sort of recall attaching a second monitor to the HDMI and having to use the Windows dual monitor settings somehow to make it clear to Windows which monitor I wanted to be the primary. I think after that initial unexpected setting that it worked as desired. Of course another thing to double-check (probably okay) is that you are running Intel's display driver (rather than some generic VGA driver). And I think that I've used some mini-DP to HDMI cables for a TV without much trouble.
