No output on monitors

[RAGNES7]

I have connected 2 monitors to my PC and they both have thier power supplies in the wall.

This is a new PC I just built it last night. When I built it all outside. I had some output on monitors. But once I setup everything and mounted monitors on wall and turned it all on...

The Cooling fans and everything in the case works fine. Power is coming to monitor, but both monitors say " no input" 

Both are connected using HDMI cables, one from graphic card and other from Mobo.

 

How to fix this? 

I haven't installed Windows or anything. Everything stock.

Well usually, the motherboard won't allow monitor output at the same time as the GPU. That helps reduce unnecessary strain on the CPU as it doesn't need to do any graphical work if the GPU is doing it all anyway. So definitely fix that.

 

Secondly, are you certain nothing changed between moving the PC and mounting the monitors? Did the GPU come loose? Any power cables come un done? Is the HDMI cable you're using okay? Try switching that out and see if it makes a difference. Perhaps it doesn't support high resolution.

I did put it in car after building it to move it from one house to another. I'll check the GPU

Graphic card is stuck
