R1
The short version
The CAC-1088 is Club3D's active DisplayPort 1.4 to HDMI 2.1 adapter, converting a DisplayPort output to HDMI at up to 4K120 or 8K60 with HDR using DSC 1.2, with no external power needed. Club3D's shop no longer lists the older CAC-1085, so this is the current option for connecting DisplayPort-only graphics cards to HDMI 2.1 TVs. The adapter is one-way, and no retail price could be confirmed here.

Common questions
Is it bidirectional?
No. Club3D describes it as unidirectional, so it converts only from a DisplayPort source to an HDMI display.
Why can't I find the CAC-1085?
Club3D's shop search no longer returns the CAC-1085. The CAC-1088 is the adapter it now lists for DisplayPort 1.4 to HDMI 2.1 conversion at 4K120 and 8K60.
