Monitor using wrong gpu!

[seretur]

I recently bought a new monitor and tried to connect it to my pc in a dual mode together with the old one.
It did not work so i decided to use the new monitor alone but if i connect it with HDMI it works fine, when i connect it on Display port for some reason it decides that an intel hd graphic card is designated to the monitor, my geforce 1080 is working only on the HDMI.
While connected with display port i can't enter the nvidia menu panel and if i connect both i can enter it but i couldn't manage to fix the problem.
In the device manager when the monitor is connected by both port i can see the two monitor cards and clearly one is with dedicated and the other with integrated.

Is there a way to fix it? Can you give me any suggestion? Thanks in advice.

Firstly.... in the bios select the GPU as primary boot... 2nd with ddu install the 1080 driver. and if it is really using the intel hd then in the control panel there should be a disable option

Just to make sure, you aren't plugging any cables into your motherboard, right?

Only into your GPU? If that's the case, that's very strange indeed. The best option is to enter the BIOS and disable Integrated Graphics Passthrough (which allows the IGP to send video out from your PCI-E GPU). If the option isn't there, your next best bet would be to simply disable the Integrated Graphics in BIOS. It should be under advanced options or something of the like. If that option also isn't there, the quick and dirty fix would be to uninstall the intel graphics driver, which should disable it or force it to fall back on generic drivers, which usually don't have the proper software to even enable passthrough, so it should "fix" the problem.

In addition to those words of wisdom you can also set your preferred(aka default) GFX card in Nvidia control panel http://www.tomshardware.com/answers/id-1980891/setting-nvidia-graphics-card-default.html . I think it also allows the user to decide which GFX card(if two are being used but not in SLI) is should use for which monitor.

You're right, I forgot about that! Nvidia control panel is very versatile and important.

yes, are you plugging it into the displayport on your motherboard or your GPU.
