My third monitor doesn't turn on. Mac could not find it, even after full system restart.

I've got three monitor, all works fine until Saturday.

Starting from today, the third monitor doesn't turn on, even after full system restart.

The monitor is linked through the HDMI port, and works fine if connected to another PC.

Second monitor connected to my iMac won't turn on. I have 2nd monitor connected via sitecom "CN-393v1.001 USB-C Multiport Adapter + PD". For some reason after sleep mode the second monitor won't turn on. there is no messages that there is no signal or some thing like that. problem is not permanent, from time to time it's working fine. the only solution right now is to disconnect the whole adapter from Mac and reconnect it. external HDD connected to the same adapter working with no problems.

Mac Pro 1.1 monitor no light, boot-up appears okay. Dead Monitor? My old Macpro 1.1 with plenty of HD space using 10.6.8 was working perfectly but when switched on again later the monitor was not showing a light and despite turning it on and off a few times I can't get it to come alive. Is there some way I can get it on again or should I consider it dead? Any help here will be much appreciated. Ta.

mac mini no dosplay Hi all. My Mac mini and monitor doesn’t communicate with each other all of a sudden. Same Mac mini, same monitor. Just doesn’t display anymore. Blank screen. The Mac mini can be re-boot smoothly, without any funny sound or heat problem as fast as I ‘feel’. I then connect the monitor with other computer, the monitor works as usual. May I know what can I do now? Since I can’t fix the Mac mini without a display.

Please give full details about your mac, system, displays, connections, OS version...

You may try resetting NVRAM.

Genius, didn’t think to reset the NVRAM! Now works fine, monitor turned on!

Thanks! ;)
