So, one day I went on a trip...
In the midst of my trip, my brother took the HDMI cable off my computer and in the other
he put it back
When I came back, I realized my computer is now using the Intel Graphics 4600 instead of the GTX 960.

Because of this, most of my games aren't playable ( They used to be on ultra with 60 fps. nowadays it runs 10 fps on low... )
The problem is, I tried switching the main graphics card in the Nvidia Control Panel, BUT
Since the GTX 960 isn't the main graphics card, it refuses to open ( Says I don't have a Nvidia card connected ), with means: It is impossible

Strangely, both Geforce Experience and Device Manager recognizes it!
I would appreciate if one could explain 2 things:

1) How do I change my main graphics card

2) Does reconnecting the HDMI cable has anything to do with it?
( I saw somewhere saying that some monitors have a graphics card within then... )

Some computer information ( If needed more, tell me so I can put :p )

Processor: Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz
Processor Speed: 3193 MHz
Processor Graphics in Use: Intel(R) HD Graphics 4600
Shader Version: 5.0
OpenGL* Version: 4.3
OpenCL* Version: 1.2

I tried doing that, but it seems of no effort. I still can't access the Nvidia control panel, it still is using the Intel Graphics Card.
You have a idea of why?

Thanks to both of you! I did change cables to see if it worked, but I just put it again the motherboard :pt1cable:
Upon connecting on the GPU, it works properly! Thanks!
