"HD 4600" - 4k resolution works with "Standard VGA driver" but fails with Intel one

I have Seiki 4k TV I am using as a monitor, connected to HD 4600 integrated via HDMI port. 3840x2160x30Hz resolution works fine during BIOS screens and in Windows 7 64-bit with default "Standard VGA drivers". When latest 15.36 drivers are installed they do not allow to select resolution higher then 1280x1024. When I am trying to set custom resolution 3840x2160x30Hz I am getting message that "this mode exceeds bandwidth" even when I am using "Advanced mode" and setting all values to make sure it does not.

I have tried "test" drivers but they made no difference.

Could you help, please?

Hello gmygmy,

Please try updating the driver to latest driver. Here you can download it:

It is also necessary to use an HDMI 1.4a cable.
