ASUS UX31A / Intel HD4000 HDMI issue

Hey guys,

I've recently upgraded to Windows 8 on my Zenbook Prime UX31A and micro HDMI port is not working at all. Basically, when I plugin microhdmi to HDMI cable to the port nothing happens. Neither laptop or TV detect a new screen. I've been reading online that this might be an issue with the driver.

I've tried multiple drivers from both ASUS and Intel's website and it's still a no go. Current drivers that I'm using on it are:

Can you please help?

Thanks,

Dragan S.
