When I tried connecting 2 different monitors to the cpu, both had 'no video input' message. When I connect these 2 monitors to my notebook, both could show the images in the notebook. Logically it would mean the cpu would be the problem. However as I could hear the cpu boot up, the keyboard+mouse light on and all cables are connected properly, I wish to double-check is there a possibility that the monitors are not working but just able to mirror the images in the notebook cause it's driven by the notebook power?- please explain why yes or no to this.
So is it definitely the pc problem?
