Incidentally, it was observed that the new iMac can support an external 8K 120Hz display: https://x.com/vadimyuryev/status/1850929080281321899 https://x.com/vad

Not sure how that's possible. With 80gbit you can only do 8K 90hz. 120hz would need the 120gbit of the 3 lane alt mode of thunderbolt 5.

  Maybe some sort of compression?

    That level of compression would kill latency and cause artifacts.

      Either Display Stream Compression or 4:2:2 chroma subsampling will easily make 8k120 fit into 80Gb/s with minimal added latency and artifacts that are barely visible to the trained eye.

        Must be subsampling because DSC gets you to 70hz at 8K.

        They fixed the spec sheet. Now they report 8k60hz.

        That's one way to do it. :)
