Why is there no HDMI 2.1 compatibility?

The Fancy Sync Box is HDMI 2.0, this means it maximum output resolutions are:

  • 4K 60hz
  • 2k 120hz
  • 1080p 144hz

It is HDR Dolby vision compatible. But why not HDMI 2.1? We will use a PS5 as an example, this applies to the Xbox:

The PS5 is compatible with HDMI 2.1, it does not necessarily offer higher quality, other than 4k 120Hz. The Fancy Sync Box uses HDMI 2.0b, which does 4k 60hz and 2k 120hz. The PS5 hardware limits triple-A games from running at 2k 120hz, let alone 4k 120hz. The hardware cannot support these resolutions. So although Sony advertises HDMI 2.1, it is not necessarily an indication of improved quality, more slightly better compatibility. For example, Fornite, a small game with regards to graphics & map size, only runs at 2K 120hz, as the PS5 cannot support higher due to graphics & CPU limitations. In addition, if your TV is 60hz, you cannot operate at 120hz anyway.

The Fancy Sync Box does not downgrade performance, it just caps it at a level which in 99% instances, will not affect you. This device is also HDCP 2.2 compatible, meaning Netflix, Disney, etc are not blocked.
