What can make a GPU to stop displaying on screen after months of mining with the GPU without display? I was tracking my mining through HiveOS android application on my smartphone but today I decide to insert the GPU in a gaming motherboard but no display, returned the GPU into mining mobo and mining works but inserting hdmi cable I got no display still...
Happens no good reason why. Or there are good reasons. Do you have a display port on the gpu?
buy this cable

plug the HDMI end into the monitor
Sometimes this will fix the issue.
If the gpu has dvi output use this cable

other work arounds
strip all the amd and or nvidia drivers on the gaming pc.
try the card in each and every slot to see it it posts and you can view the monitor
if it does load the driver and see if you fixed it.
