Is gsync built into our motherboard or screen?

Does the 17 r4 gsync model motherboard have a different part number vs a 17 r4 non gsync motherboard?

I need to buy a motherboard and I need to have gsync. I can't find the info anywhere. It looks like the gsync is built into the motherboard but I can't find the part number difference.

 

Motherboard in short.

 

I'll tell you the truth but you're not going to like it.
Gsync on laptops is nothing more than Adaptive sync + DRM. Nothing more.
If you disassemble your system Bios (or even look through it with UEFItool), as well as read some very technical posts on this forum by actual programmers here, you will see reference to "Gsync Cookie." That is basically the Green Goblin giving the ODM their blessing to allow Gsync to function on their laptop. Monitor EDID's are also programmed into the supported list, and a monitor cannot be supported unless they (or someone) pays the Green Goblin their toll tax charge. If you don't Tithe to the Great One and bow down in worship, no monitor cookie for you! That's basically it.

If you're skilled enough, you can hack in your own Gsync cookie. If you know how.

That's the newbie form of the explanation but that's enough to get you started. If you want to know how deep the rabbit hole goes, you will have to do some searching.
@Mr. Fox can you help enlighten our lost soul ?

 

Not if the eDP goes through the cpu igpu first. It needs to bypass the iGPU for it to be even capable of running gsync.

But its true its not like on desktops where you actually use the nvidia scaler/controller. Which is a damn good image scaler by the way.
