Hello Blu, I am sorry to hear that you are having issues with your system and the HD4600. I would suggest you to install the original driver provided by ASUS and check if the behavior persists or not.
You can also try our latest graphics driver provide at the following link. https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=23714&lang=eng
Remember that our drivers are generic drivers and they are made for Intel Motherboards, but you can try it.
thanks for your help.
Unfortunately, the Intel driver and the Asus does not have solved the problem.
I also tried this way (without success).
I noticed that when I uninstall the Intel driver and leave the default to Windows:
Windows sets the refresh rate to 64hz.
When I install the Intel driver monitor refresh is set to 60hz.
The new Intel drivers have a feature that allows you to set a new profile with a custom refresh. Unfortunately only accepts 60hz. Higher or lower values not are allowed.
Thanks a lot,
