    OK, this is now officially the second Sager unit I've had with this issue. If I plug the HDMi cable in, whether I use extend or duplicate display, my GPU utilization goes to .

    Any idea what's up? I've reinstalled the Nvidia driver and nothing. My old 880m laptop didn't do this but my new 980m machine does. It's identical. Even down to the SSDs I switched out from my old machine.

    I have Nvidia control panel forced to use the 980m always also. Read that this was the issue but surely that would take care of that? It looks like it's keeps downclocking or switching to the integrated GPU by mistake.

    Turn off Aero if using Windows 7. Or disable the second screen if it's unneeded.

    I'm on Windows 8.1. And the second screen isn't needed but seems a shame to not have my monitoring stuff there. How do you disable the second screen anyway? Also, I should point out, my 880m did not do this. Would rather find a complete fix rather than a temporary one.

    I don't have this issue... it's probably a 980M issue and may get fixed in later driver updates. For now, blame nVidia.

    Within Windows. Right-click on desktop > Screen resolution.

    Eh, had the same problem with my 285m (or was it the 680m?). Only then it would cap everything at 30 if connected to an external monitor. How annoying.

    I should probably do a reinstall of Windows 8 and all the drivers.... ugh. I knew just swapping SSDs out of my old unit and into this one would be a bad idea. Weird how things were running great until yesterday.
