You shouldnt be even able to see it under Display adapters since it is disabled by default on G751JY, so no need to worry about it. This laptop model has no optimus so you will be using the dedicated GPU all the time.

I'm not entirely sure how you managed to even make it show up - but you can't use it either way. The only way I know to make iGPUs show up that are not on by default is modifying your BIOS and I doubt that's what's happening here.

You appear to basically be trying to cheat the system into thinking the device is there and enabled by installing the specific set of drivers, but it's not - this is likely the reason it won't install properly. The iGPU is simply disabled on the software and maybe even hardware level. Perhaps one day, when and if DX12 comes with this magical iGPU/dGPU mixup thing, then maybe it might be worth looking at this, but for now, the Iris Pro graphics are of no use to you.

This is why I found it so pointless to get a 4860 model - it's one major feature over the 4710 is the much improved iGPU that you can't even use. It has 100MHz higher turbo clock and is the epitome of a mobile Blast Furnace. Not worth the money at all.

yes it always was in this models
no optimus = no igpu

Did you not read what we wrote? It doesn't matter what drivers or OS you have, you can't use the iGPU.

If that's not why the laptop has it ?
What is Optimus ?

Optimus is NVidia's tehnology for switching between a dedicated discreet GPU and an integrated one when graphics power isn't needed (though the Iris Pro is actually quite a powerful GPU) but the JY and JT don't have this because of the 980M...they just don't.

I have no idea why they put that sticker there, it's the first G751 I've seen with that sticker out of the 15 or so JT and JYs.

It'd be nice if they can make the iGPU on that work together with the dGPU using DirectX 12 using the new tech, though, but I imagine the extra thermal load would overpower the cooling system when running full pelt.

never seen that sticker on a G751 before,as the G751 does not support Optimus it's pointless

NVIDIA® GTX 980 M Optimus™ Support : Yes
I have Windows 10 Pro x64 with DirectX 12 feature.
There's no way to be active Iris Pro?
thx for your information

Just because the 980M supports Optimus does not mean it is enabled at the hardware level for your machine. In fact it is not. You have been told many different times and ways now, please accept it as the fact it is. Instead of repeatedly putting effort posting here and fighting with it, your time may be better spent researching this to remove doubt from your mind.

The integrated graphics are physically not accessible. This is well documented and considered a feature on the laptop as many do not like the restrictions and issues associated with Optimus. The sticker is probably there as a general licensing agreement between Asus and Intel to include the sticker on processors that have Iris graphics, certainly little thought went into the result of them advertising the inaccessible hardware on your device.
