I have a late 2014 Mac Mini that don't send video signal to my TV, via HDMI (no adapters, my mac came with HDMI port built in). Sometimes it sends signal, but it's rare, I need to restart the Mac several times to get a signal. The HDMI cable is working.
I've tried everything, restarted NVRAM, SMC, put the Mac to rest. Nothing solves the issue.
HELP!

If the cable is bent or damaged it may only work some of the time. If it isn’t fully seated in the port, it may not work all the time either. If there is anything that got lodged in either port it may also fail. Use a flashlight on both ports and cable tips are all clear from debris and the connector in the port is parallel to its outer casing. If there is no obvious sign of physical damage, then try another cable. If it still failing part of the time you may need to bring the Mac in for service to verify there isn’t some other issue.
Preponderance of reported problems does not mean preponderance of issues. It is easy to extrapolate from the numbers on the Support Community, but individual posters are not counted on the board, nor number of times a single poster replies on their own thread.
I strongly recommend working with a specialist to isolate your problem if the cable does not appear to be a problem.
There are specialists who make house calls, including myself in my local area.
The cable is 100%
I've seen a lot of Mac mini users with same problem, but nothing that I do Works!
