Googling around and including the phrase "level shifter" lead me to: http://wiki.minnowboard.org/MinnowBoard_MAX#Weak_HDMI_signal_causing_some_monitors_to_not_work https://bugzilla.yoctoproject.org/show_bug.cgi?id=7027 Thanks for the tip! As it turns out, I'm using a passive HDMI splitter: http://www.amazon.ca/Portta-PET0301D-Switch-1-5-Feet-Support/dp/B0030AZ44O/ref=sr_1_3?s=electronics&ie=UTF8&qid=1448475845&sr=1-3&keywords=hdmi+splitter and it's causing me issues. If I plug my MinnowBoardMAX directly into my monitor, then apply power to the board, the HDMI works fine. I'm still curious to know how others are solving this issue with the level shifters, it would be nice to be able to continue using my splitter (or maybe a powered splitter?).
