Use integrated Intel GPU for external display

Jump to solution

I have Alienware 17 R3 and recently decided to plug a second monitor to it through HDMI. The issue is that I can't make it work on the internal Intel GPU and it's working on the internal Nvidia 980M.

Intel Graphics settings can't even detect the monitor, and Nvidia card shows that one display is connected.

 

 The Intel graphics settings doesn't detect the external monitor and only shows the display of the laptop.

 

I want it to use the integrated GPU because the Nvidia GPU fan turns on the full power and then slows down, repeatedly. And I also don't like to use it when working on normal stuff like browsing or working.

Whenever I disable the Nidia driver, the external monitor doesn't work.

The second monitor is normal IPS FHD 60Hz 5ms display. The model LG 22MP48HQ-P

The troubleshooting that I have done:

  1. Disconnected the HDMI and connected it again multiple times.
  2. Updated both drivers to the latest releases.
  3. Updated windows to the last build with al drivers.
  4. Uninstall both drivers one at a time and reinstalled them.
  5. I connected another laptop that only has a CPU without an external GPU.o the monitor, and the Intel graphics settings detected the monitor and it worked fine.
  6. Tried to turn off the laptop display and turn on the second one but it's still working on the Nvidia.
  7. Rebooted the laptop multiple times.
  8. Tried to change multiple power options to min, max with no luck.
  9. Booted the laptop to the bios to see if a related value can be changed from there, didn't find any.
  10. I searched on the internet on similar cases and couldn't find anything related.
  11. Tried other displays and TVs as well, same issue.

I also read that the HDMI port is physically connected to the Nvidia card and nothing I can do about it unless I connect the second display to the USB C port with a converter. but I am not sure about this and I appreciate if you guys can confirm or deny this.

If you actually want to have your external monitor powered by your intel igpu then you need to use your TB3 port and the appropriate displayport adapter.  This should then only use your igpu.  In fact it will not even use your nvidia gpu because that's the way this laptop is wired.  External monitors connected to your hdmi or mini display ports are wired though your nvidia gpu.
