GTX 1080 no display

[sukotto85]

Hi all,

I am having a massive issues with no image displaying on my 4k TV.

I have a Samsung 4k TV won't display when I select the 4:4:4 mode. This mode is required to play games at 4k 60fps.

This feature worked fine on my GTX 680.

I just can't understand why it won't display any image for me.

Has anyone else had this issue?

The TV works fine until I select HMDI UHD Colour.

Which is the option you need to get 4k 60ps.

I just can't understand how my GTX 680 has no issues, yet this card does.
