Weird 4K issue, external Monitor and GTX 970M

[Mehdmano]

Hi every one

I have a GS60 Ghost Pro With 4k Monitor and GTX 970M

I play COD 4 (2007) At 4k resolution and hit 90 FPS on my 4k laptop screen and its all fine but

With my Acer S277HK 4k monitor it lags even if fps are still the same (arround 90) when under mirrored projection ( same projection on both screens)

When i projet on external only it drops to 30 fps

I baught a brand new HDMI 4K proof Cable and no différence

Please help
