I would like some expert to help me on this matter.

I have this full hd tv --> Samsung ue32eh5000, that tv has support for 4:4:4 / chroma subsampling
My GPU is Gigabyte GTX 970 G1.

I have my PC hooked up to my tv via HDMi-HDMI cable. My HDMI input on the tv is set to PC (meaning, PC mode is enabled).

My question is, is 4:4:4 chroma subsampling really enabled ?

Because, I read somewhere that for 4:4:4 chroma sub-sampling to work with Samsung TV you need a DVI to HDMI connector....

RGB output is always 4:4:4, it does not support anything else since by its very definition, RGB values are always provided for every pixel. In component video though, chrominance values can be provided for as little as 1/16th of pixels.

Since the TV will do chroma interpolation to fill in the missing values if it receives something less than 4:4:4, you could display a pattern of alternating lines or columns of different fully saturated colors. With 4:2:2, all pixels using interpolated chroma will be the wrong color.
