What chroma format does the Samsung 4K Q90R TV support in 4K@120hz signal? Does the Q90R support: 1) 4k@120hz 4:4:4/RGB or 2) 4k@120hz 4:2:2 or 3) 4k@120hz 4:2:0 And does the tv support HDR in 4k@120hz? I'm asking this because apparently the Q90R is not receiving a HDMI 2.0 -> 2.1 upgrade as its bigger brother the 8K Q900R. This means that the bandwidth of HDMI 2.0 is the limiting factor for perfect HDR 4k@120hz at chroma 4:4:4/RGB. Is anyone aware what is the best level of 4k@120hz that the Q90R can handle? Samsung has just told us that Q90R is capable of 4k@120hz but hasn't elaborated on it any further. The customer service people also have no clue about HDMI bandwidths and actual limitations. What's for certain 4k@120hz 4:4:4/RGB shouldn't be at any means possible with HDMI 2.0b.
