[Solved] High Sierra10.13.6 : Graphics EVGA GTX 750 Ti HDMI port Not working

[machackaddict]

Hi

I am trying to run dual monitors, I have graphics from the DVI port but the HDMI port is not giving me any signal. In systems prefs/Displays/gather windows - Both monitors show up, but I cannot get a signal on the other monitor. I have changed the HDMI cables but no joy.

Here is my config.plist

Here is my config.plist

No need to paste it into the thread - Attaching it is quite enough.

 

[machackaddict]

ok, didn't know how to attach it, but suppose I can pasted into a Text file, then attach that in future.

I have fixed the issue, It was something daft, The DVI port was working on both monitors, when I plugged in the HDMI to the main monitor, it was not auto switching to that input. So changed the input and it now works. Thanks
