Cannot Achieve 144hz with Alienware 15 and Asus VG248QE

[lordrenrew]

Did massive searching a could not find an answer.

The Asus VG248QE supports DisplayPort, Dual-link DVI-D, and HDMI ports. Currently I am using an Apple Mini DisplayPort to DVI adapter, it looks like it's dual link, but I do not believe it's active.

No option to on the Nvida Control panel to change resolution or frame rate. Can only be achieved through the CPU control panel which I've heard is normal for laptops. When I try to do a custom resolution and bump up the refresh it says "The custom resolution exceeds the maximum bandwidth capacity".

Is the simple solution buy a Mini DisplayPort to DisplayPort cable or is it not possible the output ports are connected to the CPU and not GPU? Will buying the right cable magically put resolution and refresh rates into the Nvidia Control Panel?

I believe this is the DVI Adapter I have: http://www.amazon.com/Original-Apple-Displayport-Adapter-Mb570ll/dp/B014Z7YJ4Q/ref=pd_rhf_dp_s_cp_4?ie=UTF8&dpID=21EhsV1ioIL&dpSrc=sims&preST=_SL500_SR135%2C135_&refRID=0R7WPFHCQC44Q5QAEKPJ

Thanks guys!

The adapter in that link is not dual link dvi(according to apples site) so it will not support 1080p@144Hz. You'd need a mini displayport to dual link dvi adapter and those are not cheap.

But where the monitor has a displayport just get a mini displayport to dispalyport cable.

Understand that they are expensive. Thanks for confirming that it is not dual link. Since the monitor supports a DisplayPort I should purchase a Mini DisplayPort to DisplayPort cable. That would fix the problem correct?

Yes, assuming the gpu supports it.

I have an NVIDIA 980M.

Going back to one of my previous questions. Getting the right cable will that allow me to change refresh rates in the NVIDIA Control Panel? As it stands no such options are present and the only settings that show up are "3D Settings".

Yes with the proper cable it should show up as an option on the control panel.

No you cant because the NVIDIA is manually conected as rendering GPU to the ports of onboard iGPU, so you just can setup the resolution and refresh rate at intel driver.

there is a post on another forum that explain that change the driver to intel default driver should enable 144hz refresh rates but couldnt never reproduce and confirm that solution.
