The laptop display is routed to the iGPU only, so you are bound by switchable graphics (which GPU gets to do the workload essentially). You cannot run the laptop display on the GTX 970m, but the HDMI port is routed to the GTX 970m.

Not sure what you mean - both devices show in Device Manager:

Then what you see depends on how your system is configured.

Using the laptop display:

and using the HDMI port:

You can see the 970m is directly driving the HDMI output (which is braindead) and the onboard graphics drive the laptop display; however, the 970m GPU can be used for the laptop display, but the actual rendering is always through the HD530 itself (so even thoguh you use the grunt of the 970m, the resolutions and refresh rates are limited by the onboard graphics).

When you use the HDMI port, the 970m is used directly, but then the resolution and refresh rates are limited by the HDMI standard (which is why it is braindead - should have used DP there).

That's my understanding of the situation, would appreciate clarification of I'm wrong.

Thank you hindesite for this! With this hint I could successfully run C&C Red Alert 3 in all its glory with my GTX980M
