[SOLVED] Is it possible to run 8K with HDMI 2.1 at 60Hz 10bit ycbcr 4:4:4 color

[Amigo1982]

Hi,
If i buy 8K TV with HDMI 2.1, 10 bit panel and i have HDMI 2.1 cable and Graphics card RTX3060 Is it possible to run 8K at 60Hz 10bit ycbcr 4:4:4 color. in Windows 10.
I am not interested at RGB color or chroma 4:4:2/4:2:0 etc. Will play no games but image quality is best at ycbcr 4:4:4
For example i am now with LG OLED65E8 TV which is 10 bit but because it is HDMI 2.0 i can get max 8 bit at 60Hz ycbcr 4:4:4 at 4K. I CAN run 4:4:4 60Hz 10 bit BUT RGB color I see confusing info on internet. Is it HDMI 2.1 limited to 8k 60Hz RGB only or can run ycbcr Please if somebody has the hardware (8K TV + card + cable, all this with 2.1 version HDMI) to check and confirm!

The short answer is no. 8K, 10-bpc color, 60Hz requires 59.7 Gbps. HDMI 2.1 caps out at 42.6 Gbps*. Compression is required to achieve either 8K 60Hz or 8K 120Hz.

EDIT: The HDMI spec says HDMI 2.1 is capable of 48 Gbps, but this is the raw bandwidth. Accounting for 16b/18b encoding, it drops the usable bandwidth to 42.6 Gbps.
