UT3 received - screen blank on 4K TV

[jamba]

Just received my UT3 and the screen is bank on a 4K TV. Connected to a 1080p (it works) and the Screen Settings only shows a resolution for 1080p.

Upgraded to latest firmware and still shows a blank screen on the 4K TV. Please help...

I had the same in my menu. only 1080p.
Reboot the box a few times and 4k may show up in the menu.
It did on mine.
