8K HDR implies that DSC becomes unavoidable...but DSC's "visually lossless" criteria relies on the human eye and is statistically subjective at face value.

Any domain experts know how that actually squares in practice against automated colorimeter calibration?

DisplayPort 2.1 (which the monitor supports) provides sufficient bandwidth for 7680x4320@60 Hz 10-bit without DSC when using UHBR20. The press release unfortunately doesn’t clarify whether the monitor supports UHBR20 or only the lower UHBR10 or UHBR13.5 speeds. Of course, the GPU must also support that (Nvidia RTX 5000 only at the moment, as I believe AMD RX 9000 is only UHBR13.5).

I believe you're right regarding AMD's lack of UHBR20 on its cards. Fingers crossed for their next gen!

AMDs current workstation cards do support UHBR20, just not their consumer cards, even though it's the same silicon. Artificial segmentation on GPUs is nothing new but segmenting on display bandwidth is a strange move, especially when the market leader isn't doing that.

8K 60fps 4:4:4 8bpp uncompressed requires a 96gbit HDMI cable, which is labeled Ultra96 in HDMI 2.2 afaik: https://www.hdmi.org/download/savefile?filekey=Marketing/HDM...

DisplayPort over USB4@4x2/TB5 at 120Gbps would be required for uncompressed 12bpp.

Apologies for not tracking; the monitor in question is spec'd with HDMI 2.1 and TB4 I/O.

Apologies never expected when it comes to USB and HDMI naming and spec stuff. I have to look them up every time.

But, that’s 8K DSC or.. 24fps maybe? then. Weird oversight/compromise for such a pro color-focused monitor, perhaps Asus reused their legacy monitor platform. “8K HDR” at 24fps could be a niche for theater movie mastering, perhaps?
