Macbook PRO M2 Max and 8k display

[Lazyass0]

Hi,

just checking 8k@60 compatibility and I found something strange regarding display option on acbook PRO M2 Max ...

For one display there is no 8k@60 possible over Thunderbolt, but if we look at two displays it clearly says one 8k@60 over Thunderbolt AND one 8k@60 over HDMI.

Now or is that mistake and they put 8 instead of 4 in that line, OR it works 8k@60 over Thunderbolt IF you also connect one 8k@60 over HDMI at same time ?

What do you think ? Has somebody tried 8k@60 over Thunderbolt ?
I have just send feedback to Apple and also contacted support but on support they don't know that and will also forward this to their team

Pretty sure that's a typo and should be 6k, considering it's specified as thus in every other place, I don't think there's a display port spec for 8k yet?

For 8k@60hz 10bit yes, it is DP 2.1 UHBR 20 which caps out at 80.00 Gbit/s ( 77.37 Gbit/s ) without compression using 4 lanes 8K, 10-bpc color, 60Hz requires 59.7 Gbps.

This is probably not implemented in any MBP yet, since it was defined from VESA last autumn Maybe they can enable it later since it is USB4/TB4 chipset ...
