Hi all,

My specs:

Intel i7 12650H

RTX 4060 Laptop Graphic Card

Long story short but I've upgraded the stock 1080p panel to a 1440p 165hz IPS panel (N156KME-GNA to be exact). It's also featured in the Asus ROG Zephyrus G15 laptop which features a Ryzen 5 5900HS and RTX 3080 Laptop Graphic Card.

I was just wondering is it possible to get freesync from the panel working with the discrete GPU?

It does work if using the intergrated intel graphic card and shows VRR and adaptive sync options both in Windows settings and intel command centre. I've confirmed it works with both Nvidia's pendulum demo and AMD's windmill demo. The iGPU shows no tearing with vsync off but when using the dGPU, tearing is visible.

Can anyone explain this? I assume the iGPU and dGPU are connected to the laptop's panel differently?
