Hi, I tried to connect the Oculus Rift to the HDMI port on my Lenovo Legion Legion Y520 but the HDMI seems only connecting to the internal 630 graphics. I tried setting PhysX to the 1050 but it always stays connected to the 630, it does not change despite forced setting to 1050. When I plug in an external monitor to the HDMI and disable the 630 in the device manager, the external monitor turns black. When I disable the 1050 the monitor keeps working. The Oculus is extremely laggy and cannot be used over HDMI since only the 630 feeds it. What can I do to connect the HDMI directly to the 1050 GPU?

OK, I found the answer: NVIDIA Optimus solution („MSHYBRID“) where the GPU is channeled over the internal 630 is the bottleneck and is not supported by VR headsets. They need to be connected directly to the GPU. It will never work with the Y520 and I returned it.

I'm not sure I fully understand the problem, but I was able to get the oculus to work with the y520. I've got the model with the gtx 1060 graphics card (specifically the Y520-15IKBM model), and it has a mini displayport on it (the other models apprently don't have one). I bought an hdmi to mini dp adapter (specifically the Cable Matters 4k ready adapter ). For some reason, this fixed my issue. Seeing as you have the model with the 1050, I don't think your laptop has a mini displayport, but I'm just leaving this here for future reference.
