Hi,
I received my UE55HU7200 this Monday and so far very pleased.

Now I would like to display some 4K video from my PC to the TV. I have a GTX 760 and tried NVIDIA drivers 340.52 & 344.65. I have set up HDMI port 4 since 1 & 2 I used for TV / XboxOne) and renamed it to PC.

Also I have set the option HDMI UHD Color to "on" on the tv.

When I set the TV using resolution 1920*1080 all OK. However, when putting my TV to 3840*2160 (native) the tv goes blank and the tv gives the "no signal" message.

Any idea what I am forgetting here?
Cheers,
Dirk

You're spot on. When searching for this I found the following at http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-760/specifications

1 - 3840x2160 at 30Hz or 4096x2160 at 24Hz supported over HDMI. 4096x2160 (including 3840x2160) at 60Hz supported over Displayport. Support for 4k tiled MST displays requires 326.19 driver or later.


Is there a whole different cable for that or can I use a display port output to HDMI converter?

Ah, I see. The adapter is the way to go then.

Yeah, the TV doesn't have it.

Although when setting the resolution to 3840x2160 at 30Hz it has the same effect (and it states that it is supported)...

1. I just want to use it for 4K video (not gaming) so 30hz should do right?
2. Any idea what could than still set the TV to go blank?
