Optimus Laptop w/duplicate external monitor limits laptop to 60hz. Fixable?

I recently built a streaming PC to live stream the performance of these gaming laptops. I'm currently working with the AERO 15x. I'm capturing the stream with an Elgato HD60 Pro on the Streaming PC with an external monitor via HDMI from the Stream PC and HDMI into the Capture Card into the laptops HDMI.

Everything works except one thing. When in-game, the laptop limits its Hz to 60 regardless of the frame-rate.

There's several workarounds on this but nothing so far on a solution that is specific as mine. Everything covered that I have seen is not for laptops.

I have this AERO 15x with its 144hz panel and I would like to enjoy it while capturing the stream at 1080p/60.

 

You have v-sync disabled?

AFAIK HDMI doesn't limit FPS, so it would be odd if it was capping the game's rendering engine to 60FPS.

My guess is the capture card isn't going to capture over 60FPS though.

 

The 60s is limited to outputting 1080p60hz so you won't be able to enjoy higher from the 60s source. Your laptop itself should still be able to use 144hz though.

 

I can get this working just fine on my main laptop as it does not use optimus technology.

Apparently on laptops that do use Optimus technology when you plug in an external display, that display uses the dedicated GPU and the laptop screen is right off of the integrated GPU. When you fire up the game for whatever reason you’re getting the frame rate that you’re supposed to get but the frequency on the laptop display limits itself to 60 Hz

I’ve been working hard on this for the last 48 hours and have learned quite a bit.

I’m all ears if someone has evidence to debunk my findings. As I would really like to get this to work.
