It is a rare issue. Let’s try to narrow down the problem. Using the VGA port, get into the BIOS and reset settings pressing F9 then, save changes with F10.
Turn the NUC off, change manually the TV video input setting to HDMI then, turn the NUC on, let see if you have video.
Test your system with 1 memory stick of DDR3L-1333/1600MHz at 1.35V SO-DIMM.
Hi Mike. Thank you for the response. The Monitor is a BenQ E2400HD. I think the standard of HDMI that it supports might be too old. That is why it can't properly get a handshake. I tried the Sony TV, which is newer, and it worked fine. When I set up my projector, the real reason why I bought the NUC, I will try that out as well.
Thank you so much for your support. Hopefully other people with this problem will check what HDMI version their monitor is.
