lizard050,
I've never had a problem going direct with my ETD. Even with my little netbook 1st gen atom loaded with windows 10 preview. I've been testing with xlights 6000 channels all week. Etd has been found every time. Now I've probably been lucky,and I run my display direct connected from my show computer for 2 years.
Check your xlights set up. Delete any left over settings. Set up e1.31 protocol with 32 universes. Reboot ETD and controllers, and try a test. I don't understand that you have a yellow fast blinking light and no output. It says to me a configure problem in the software. I'm only giving you what works for me. I'm just offering, maybe something you over looked or you could try.
