    HD4600 UHD Displayport MST

    Seppdog

      Hi!

       

      I have a Panasonic TX-65AXW804 UHD TV and I connected it via displayport to my pc.

      The problem is that with UHD (3840x2160) resolution I can only select 60Hz. But the TV can also 24Hz and so on.

      At 1920x1080 I can select all refresh modes but the TV stays black.

      When I switch the displayport to SST on the TV side, I can select all modes correctly according to the specs:

      All FullHD modes and UHD at 30Hz (maximum for single stream) and it works.

       

      With older drivers, the PC show me the TV as 2 different Monitors.

      So it looks like the driver dont detect the TV correctly in MST mode.
