I have a AN515-53-55G9 and when I play a game with the internal monitor I can play most games up to 140 fps and I hear the fans for the gpu kick on as soon as I load it, when I plug an external monitor the fans shut off and I struggle to maintain 30 fps, I unplug the hdmi and everything comes back on. Is there a setting or option Im missing?
