Which Intel HD GPU models support 8K monitor (e.g. Dell UP3218K) via dual-displayport 1.4 cable?

[MM16]

The Dell UP3218K 8K monitor uses TWO Displayport 1.4 cables to deliver its 8K 60Hz using a technique called MST and DisplayID.

The technique is described in this VESA document https://www.vesa.org/wp-content/uploads/2016/06/Display-Summit-USA-2016-AMD-VESA-SAH_Final_r1.pdf at page 10 for instance, also mentioned by Nvidia here https://www.nvidia.com/en-sg/geforce/products/10series/compare/ ("7680x4320 at 60 Hz RGB 8-bit with dual DisplayPort connectors").

Which Intel HD graphics versions support this MST-DisplayID tiling feature, so that I can connect this 8K monitor to TWO of that laptop's displayport?

(..which is provided via its two USBC-Thunderbolt3 connectors, e.g. via an USBC-Displayport adapter or via the Displayport output on two Akitio Node Pro:s https://www.akitio.com/expansion/node-pro.)

Thanks!

A bit of own followup:

7:th gen mobile https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/7th-gen-core-family-mobile-u-y-processor-lines-datasheet-vol-1.pdf is Displayport 1.2, I think those are too old for 8K@60Hz dual cable, I think that support started around Displayport 1.3-1.4.

8:th and 9:th gen mobile https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/8th-gen-core-family-datasheet-vol-1.pdf is still Displayport 1.2 only, duh.

There is an announcement here https://www.notebookcheck.net/Intel-Ice-Lake-Gen-11-iGPU-will-support-DisplayPort-1-4a-and-Display-Stream-Compression-for-5K-120Hz.336622.0.html saying that the upcoming Intel Ice Lake CPU:s will have Displayport 1.4 support.. so.. that's it, CPU:s released to market late 2019 will have the support, or?

Hello MM16

Thank you for posting in the Intel Community.

The current Intel graphics controller supports 4k@60Hz (https://www.intel.com/content/www/us/en/support/products/98909/graphics-drivers/graphics-for-7th-generation-intel-processors/intel-hd-graphics-630.html), for the Intel® Ice Lake processors we cannot comment about on non-release products.
