I have just bought the new 34010 today and have had a nightmare so far. All the years of building PC's and I've never had problems like this. I set the machine up in the back room with the machine hooked directly up to the tv. Everything boots up works fine I brought it into the living room and plugged it into the hdmi in on my yamaha ax861se amp and I couldn't get a picture. I've run a full size PC previously though this port with AMD graphic cards and not had a problem. For the last two years I've run an apple tv through it without any problems. I also use a hdmi splitter to send the signal to my projector as well. Again, all my previous devices didn't have a problem with this. So during fault finding I removed the splitter and plugged the hdmi out from the amp directly to the tv. Brilliant, I have a picture. Not brilliant I can't use my projector now. So I thought, oh well, I'll leave the projector for now, it might be a cheap splitter box causing the issue. So I used my nuc for a while and then changed the source on my amp to my sky box. Switched it back later and it crashed my nuc. Tried a few times and every time it changes source the nuc crashes and reboots!! Come on, its a fresh windows 7 install. I have to assume its a HDMI handshake issue or something related to the intel graphics.
PLEASE intel something fix this. You have ignored the original posters problems. This is the first time I have bought an intel product and will liely be my last if I can't get this fixed.
