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?
Please try updating the driver to latest driver. Here you can download it:
It is also necessary to use an HDMI 1.4a cable.
