HD4600 - 2560x1440 144Hz

[DWard9]

Hi,

I am using an Alienware 17 R2 with an Intel HD 4600 and a Geforce GTX 980m.

I have attached an external display Asus MG279Q. This display supports a resolution of 2560x1440 at 144 Hz.

However I can only select that resolution with 120 Hz. 144 Hz is not an available option although it is displayed in the Intel support information.

Any idea how I can set this mode 2560 x 1440 (144p Hz)?

(and yes it is connect thru display port)

Hi ivanu

sorry but that is not answered in the FAQ.

Is there a list of supported video modes with refresh rates for HD 4600?

Thanks
