It seems that 7th gen and later Intel processors can support HDMI 2.0, but only with an external "LSPCON" (Level Shifter and Protocol CONverter) component on the motherboard.
As I've mentioned before, going through DisplayPort also works and does not require a LSPCON. I love how it mentions future generations won't need it. Unfortunately

I wonder if they will skip 2.0 and go to 2.1 when they finally get around to updating that design. If I recall HDMI 2.0 like USB 3.2 and PCI 4.0 does not require a hardware upgrade. The protocol changed but older hardware should use it depending on if it can handle the new requirements. This was one of the reasons AMD did allow for awhile, PCI 4.0 on older Ryzen chipsets.
If HDMI for the last two versions is like this it really doesn't make sense to not allow it on certain older computers. Probably just a way for Intel to sell more chips maybe. I could be mistaken but from memory this is what I recall, Nick
