HD4600 UHD Displayport MST

[safas]

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.

Hi Seppdog,

After investigation we've determined this feature to be fully functional in our driver and your issue appears to be panel specific either with just your specific panel you physically have or with the model you have. I apologize for the inconvenience, and I'll be closing out this case now.
