Use HDMI 2.0 Cable

Try with HDMI 2.0 High Speed Cable which supports 4K/60. Samsung manual says to use HDMI cables less than 6". Give a try and post your experience.

The Television can accept whatever the resolution is that is being sent out by the output device. The television is more of like a monitor, you would need to check the manufacturer of your device to see how to change the output resolution settings.

Yes its connceted to a 1.4 cable and a R9 295x2 AMD Video card. If I set it to 3840 x 2160 60hz I get resolution not supported on the tv. 30hz work but not great.

Remember that 1.4 connections are like that.

It's a limit of that connection (1.4). Sorry but that is all over the web, hope Samsung has a long explanation for you.

Problem solved

The only way to get 3840 x 2160 was by patching the drivers but after doing that I notice this card ONLY support up to 30hz meaning playing games at 4k was useless so I sold my card and got 2 gtx 980s I also change my cable and bought a monoprice slimline Redmere cable 18Gbps. So I got everything working now.. Thanks for all the help guys..

Hi spawn1980.

I just bought this card too under the impression it would output 3840x2160 to my Samsung UE65HU8500 via High Speed HDMI but am experiencing the same issue as you. 'Maximum reported resolution: 1920x1080' on CCC.

I've been chatting with the guys at XFX to try to resolve this issue but as it stands they have ignored my last email for 7 days. Did you manage to get the card to output 3840x2160 even at 30Hz or not? I've tried everything I can think of. Tried shorter HDMI cables...

I was reading into this a bit on the net and it looks as though by using either of the two adapters that come with the card (Mini DP to HDMI and DVI to HDMI) will not output any higher than 2560x1200. Is this the case?

If you did manage to get 3840x2160 from the card, whether 30Hz or not, please could you tell me which drivers you used?

Your help is greatly appreciated. This is my first AMD card and I'm coming close to never using one again...

Thank you!

Thanks spawn.

Will most likely give that a try tonight.

I finally received a reply from XFX this morning. They said this...

"Sorry for late response. I have contacted our engineer and they informed that the maximum resolution of DVI to HDMI is 3200x1800, miniDP must be used for 4k display. If the miniDP need to be converted to HDMI, the resolution will be limited by the adapter.
In your case, it seems the miniDP to HDMI included seems not able to support the resolution, so you would have to purchase a 4k compatible adapter. Sorry for the inconvenience caused."

Maybe if I get myself one of those I wont have to mess around with the pixel clock patcher etc.?
Will keep this post updated.
