I'm wondering if there are any tricks for resolving this issue, or if there is some other way to connect a second display without resorting to USB.Ĭonsole log around most recent failure: 10/2/14 10:14:16.956 AM WindowServer: Received display connect changed for display 0xb4135b0ġ0/2/14 10:14:16.957 AM WindowServer: Found 19 modes for display 0x0b4135b0 ġ0/2/14 10:14:16.968 AM WindowServer: WSDisplayPipeTransactionEnd returned error e00002beġ0/2/14 10:14:17.015 AM WindowServer: Received display connect changed for display 0x3f003dġ0/2/14 10:14:17.015 AM WindowServer: Found 1 modes for display 0x003f003d ġ0/2/14 10:14:17.015 AM WindowServer: Received display connect changed for display 0x1a49c79eġ0/2/14 10:14:17.015 AM WindowServer: Found 1 modes for display 0x1a49c79e ġ0/2/14 10:14:17.015 AM WindowServer: Display 0x1a49c79e changed state to offlineġ0/2/14 10:14:17.049 AM WindowServer: Display 0x0b4135b0: GL mask 0x1 bounds (0, 0), 19 modes available I'm guessing that there is something going wrong with the graphics chip or HDMI interface logic.
My best guess is heat (if I leave the box off for a long while it starts working again) but everything I've tried to control heat hasn't worked. I took the same cable, connected it to a HDMI-Thunderbolt adapter, plugged it into the Thunderbolt port and it comes right up.
#Will late 2012 mac mini 1080p
The system is in the state where it is ignoring the HDMI port, and I did the following test: using a Belkin HDMI cable to a 1080p monitor with an HDMI port, I connected it to the Mini's HDMI port and nothing. I never have an issue with the display connected to the Thunderbolt port. Rebooting doesn't help, although if I leave the system off for a while, it will sometimes come back. It goes blank and OS X does not recognize that a second display is connected. When I hook up two displays to the Mini (one Thunderbolt, one HDMI) it will configure and work properly for a time.Īfter 1-2 hours, or if I do something graphically intensive (start a game) the HDMI display will drop out. I have a late 2012 Mac Mini running OS X Mavericks (10.9.5).
