CAC-1310 HDMI or CAC-1070 adapter 10 bit YCbCr 4:2:2, YCbCr 4:2:0 TV

My dilemma is my Samsung 49ks7000 TV isn’t receiving 10 bit in support from my GTX 980ti 2.0 HDMI port even though other users are able to see the option with lower GTX 960 on similar 10 bit panelled 60ks7000.

This made me think it may be a cable issue but when I came to order the CAC-1310 I noticed that it didn’t support my TV’s 10 bit YCbCr 4:2:2, YCbCr 4:2:0 but covers the  RGB 4:2:0, RGB 4:4:4 @10bit So is there anyway me been able to see the option with a different cable or the CAC-1070 adapter through the 1.2 display port to the HDMI 2.0a port on the TV?

Hi Optical10,

In general …

CAC-1310 is and HDMI2.0 Cbale certified by HDMI.org to support full bandwidth and full specs over 3 meters, so that is most probably not the issue.

This is what the Adapter CAC-1070 supports:

  • Setup

Setups with TV’s normally work best by making a custom resolution, in this case for: 3840*2160 at 60 Hz with Timing Standard set to CVT-RB (Reduced Blanking ).

(For setups with Monitors Timing Standard can remain on “auto”.)

On most  TV’s you will need to do some settings  like  “Enhanced Mode”/ “PC-Mode” and/or  “UHD Color” for the HDMI 2.0 port in use.

Please make sure the HDMI port of the Screen/TV supports 4K 60 Hz, often not all HDMI inputs support that.

Please make sure the Software of the TV is updated

You screen is most probably “telling” your system (by EDID at boot) it can do 4:4:4 in 4k60Hz.
This will make your system automatically jump to 8Bit BPC. BPC at 10 bit with 4k 60Hz will make the signal too big for HDMI2.0. Making a custom resolution will “over-rule” that auto settings part.
