intel IRIS Xe with MST problem

laptop:ASUS ZenBook 14 UX425EA, CPU: intel i7 1165G7, to connect a synaptics VMM5200 MST hub (It's a DP1.4 to dual HDMI2.0b MST hub IC)

driver V27.20.100.8439 can works normally at dual 4K@60Hz.

driver V27.20.100.8853 one of the monitor can only output 4K@50Hz and unstable. 

driver V.V27.20.100.8890 is not normal.

I found the unstable driver cannot deal DSC correctly.

Hello @ATsai15

Thank you for posting on the Intel® communities.


We found another thread describing the same issue and the same hardware/software environment as this one. To avoid duplication of effort, we will close this thread.

We will continue working on this one: https://community.intel.com/t5/Graphics/intel-IRIS-Xe-with-MST-problem/m-p/1225738#M91273


Thank you for your understanding.

Best regards,
