Q: external display issues (15" pro, mid 2015 retina)

my macbook pro (15" - mid 2015) is having intermittent issues when connected to an external display (a Samsung UN22F5000) via an HDMI -> DVI which is then converted to mini-display port via apple's adapter.   Every 5 minutes or so the display will disconnect and then reconnect after a second or two of static.  This happens repeatedly.  I've swapped the mini-display port adapter out, same issue.  I even mored the HDMI to the "DVI" port on the tv and the issue persists.  I dont seem to have this problem when connecting my other MBPro to this display using the same cable config (mid-2012 15" retina), or when it's hooked up to my dual display config at work.   Any ideas here?

 

Thanks,

David

    Hello drock3800,

     

    Thanks for using the Apple Support Communities!

     

    I understand that you are having issues with video on your display, specifically with one Mac where your other Mac computer’s don’t have that issue. I see as well that you have already completed a lot of great troubleshooting but the issue continues. 

     

    To continue the troubleshooting process, I suggest reading over and working through the suggested steps located in the following article. A lot of the steps you may have already completed, but there are several such as resetting the system and resetting the resolution that you may not have completed yet.

    Have a great day!
