A717-72G getting way better fps on external monitor attached.

Hello, I've had that issue for almost 6 months trying to resolve it with no luck. I was trying to play overwatch on lowest settings expecting stable 144 fps. However, I get 100 fps everage. I have googled a bit and there was info about nvidia optimus tech which is using intel gpu to output frames to the screen even if your gtx 1060 renders it. So i plugged my 144 hz monitor to my laptop to see if it would be better, and yes, it was. Is there any way to overcome the lowish fps on laptop screen itself?
I am feeling kinda sad because I am getting stable 150 fps in overwatch on outdated gtx 970 and i7 3770 with slow ddr3 ram and yet its only 100 fps average on the laptop...

That image is an exact copy of the original specsheet with both the ACER and Mfr part numbers. Google either number for the complete specs. It's possible other screens were used after publication and/or in other regions. But it's likely that they would've had the about same refresh times from the assemby plant. Better compatible screens are probably available. Jack E/NJ

Thank you for the answer. Now I am 100% sure its a regional thing for me since I could never find similar laptop in any other country store (the model name is 717-72g-77AM which simply doesn't exist in any US store). Also I've been running some apps and tests and it showed 144Hz, but its not actually relevant to my problem which I've described in my first post.
The actual solution to my problem which I have figured out by myself (neither acer support nor nvidia support could help me with that): I've just installed dual channel 2x8gb 2666MHz 15 CL ram instead of standard 8gb Hynix one into my laptop - my fps is easily FAR better anywhere I've tried so far. Still have no idea about fps difference between external monitor and actual laptop screen, but it doesn't really matter anymore.

Sorry, the stock LCD screen can't be driven above 120Hz max. Jack E/NJ

Thank you for the reply. However, in a nutshell my issue is: 160-180 fps using external monitor VS ~100 fps on the laptop screen. I want to get decent stable fps on my laptop without external monitor (let it be stable even 120 fps, as you say it can be driven above 120 hz).

UPDATE: P.S. Can you please actually explain the thing about 120Hz max? The model I have has 144hz screen in specs on the website, also I checked the LCD screen with aida64 utility - the screen model is AU Optronics B173HAN03.2, its listed as 144hz one everywhere on the Internet.

Only 3 LCDs listed in the specsheet. Two with 8ms refresh times (125Hz rate) and one with 25ms (40Hz rate). Jack E/NJ

The panel model in this list isn't even the same as mine which I got from aida. Can you please link specsheet if possible?
