DisplayPort Sink | 2 Pixel per Clock Video | Output not correct

Hi,

I am using a DisplayPort IP core as sink, two 2.7 GB lanes, 1920 x 1080.

It works perfectly with 1 pixel per clock.

For a new project I need video data with even and odd pixels output

So I configured the IP core with 2 pixel per clock and after generation the video data output port of the clock recovery core has a width of 48 bit as expected.

But only the lower 24 bits contain video data, the upper 24 bits are always 0.

The pixel clock output of the clock recovery core amounts to 74.5 MHz, the clockx2 output 149 MHz. So the clocks seem to be correct.

Is there some additional setting i have to configure to get a 2 pixel per clock 48 bit video output?
