Bad Performance when connecting Laptop to TV

[Fbh]

Hi guys.

I'm having issues with Performance on my Laptop when I connect it to my TV (direct connection over HDMI).
Performance in games is taking a significant hit. For example, areas in Quantum Break that would at most drop to 55fps when playing on my laptop screen are now dropping to mid 30fps and I really don't know why.

I've asked this in other places but I tend to get the same replies and none of them have worked.

- Is your integrated graphics card taking over ? No, it's still the dedicated GTX1050ti doing to work
- Are you displaying on both the laptop scren and TV? No, I have it set to only display on the TV
- Is the game displaying at a higher resolution on your TV? No, the game is allways set to 1080p and mid setting when playing on both my TV and my Laptop screen
- Have you updated the drivers? yes, all the drivers on my laptop and on their newest version.


So, any suggestions?

Laptop Spects:
Quad Core i7 7700 HQ 2.8 Ghz
16 Gb ram
Gtx 1050Ti


Thx

does the gpu or the display do the scaling?

As far as I know, the TV.
But where do I have to check to be sure?
