Hello.

I have connected my Samsung Ue49ks7000 to my R7 260x and with custom resolution I been able to achieve 4K@60Hz. The problem is the screen keeps going to black and then turning on again, like random and continuous blinks.

Any suggestions please?

Thanks you very much.

Hello jcferraz,

Samsung TV often need to be set to “PC” for the HDMI you use to connect to the PC.
It is also often needed to set the TV to UHD Color.

Waht brand/type HDMI Cbale are you using ? or in ither words, you sure that one is capable of supporting 4K 60 Hz or 18Gbps ?

Hello.

You are right and the answer was the cable. Now I’m able to achieve 4K@60Hz. 

I was wondering… Is it possible to achive 10b color deep with CAC-1070 and my graphics card? My TV has 10b but Crimson only allows me 8b.

Thanks again for all your help. Great tech support!

To allow support for 4k@60Hz at 4:4:4 the Bits per Color needs to be at 8Bit otherwise the signal gets bigger than HDMI2.0 has bandwidth for. So that Crimson driver most probably just jumps automatic to 8bpc and does not allow you to change.
