Hdmi problem Mac Mini 2018
Hi,
i bought a new mac mini 2018.
Processor 3.2 intel i7
Memory 16go
Graphic Intel UHD Graphics 630 1536MO
I am using the hdmi port connected to my receiver and then projector.
I am using one display port connected via one TV full HD using an apple adaptater.
For the hdmi port, everything works fine except that the screen goes black intermittently and comes back after 3 or 5 seconds. The monitor and cable works well with other computers. I also checked the connection and upgraded the OS to the latest one. Nothing helps.
I unplugged the HDMI cable and plugged it into USB-C using an adapter. It still has the problem.
The only difference is coming from the black screen. Using hdmi direct, it’s coming blue like there is no source on projector. Using hdmi with display port adaptater, it’s coming black screen.
All the HDMI cables that i am using are quality standard. Version 1.3 or 1.4. I tried to switch many things. No good results..
Also, it happened usually when watching a movie through the Kodi app or directly on the desktop.
Strange things, it never happened when i am on safari doing some research or watching a video.
What do you think? I thought it was coming from the hdmi port or adaptater but it looks like not.
So, it’s coming from the cable using? The receiver? The projector?
The receiver has 4 input and one output.
I never had a probleme with any other input. I used to use a macbook pro instead of this new mac mini. Never had an issue as well. The output was and is still the same. It’s the projector.
All drivers are up to date on the receiver and projector.
The receiver is Yamaha Rxv 467 and Projector Epson TW-1000. (Yamaha is using 1.4a hdmi input and Epson Projector 1.3)
As i said, all the other sources have no problem: ps4, ps3, bluray, tv box,...
Then, i did a test not using the receiver and projector. I tried using my full hd tv on hdmi direct and display port with adaptater.
i had no issues on both.
Tv is a full hd sony classic from 2011/2012.
Therefore, I thought about a compatbility problem with some hardware or some issue on Osx. I read it happened in the past with old mac mini 2012 and 2014.
Or a crazy issue not compatible with some hdmi cable between the mac and my receiver.
What do you think? I am lost.
Hdmi from this new mac mini 2018 look not stable to me.
Forgive me if i was not enough clear. I tried to do my best.
I just ordered a new hdmi cable 2.0 with good quality in order of checking if it’s coming from there but i am not sure.
Please help.
Thanks a lot.
Mac mini 2018 or later
