Diplay Port RX subsystem 2.1 for Kintex-7

Jump to solution

Hello,

Does the DP RX Subsystem 2.1 works fine at 120 fps in stereo video mode with resolution 1600x1200 for each stream ?

(2 streams so 240 fps)

 

The DP support 1.2a standard but the document about the Display Port doesn't talk about the support of 3D clearly.

 

Where does the 2nd stream will be presented on ? on AXI4S Video Str2 ?

 

Furthermore I would also need to know if switching from mono to stereo is dynamic.

 

Best regards,
Andrea

Hi @andreac_avnet,

 

I didn't answer because I thought they were related to 3D...

 

Where does the 2nd stream will be presented on ? on AXI4S Video Str2 ?

Yes in the case of MST

 

Furthermore I would also need to know if switching from mono to stereo is dynamic.

This is related to 3D which is not supported.

HI @andreac_avnet,

 

Theoretically, the DP IP should support 2 streams 1600x1200@120Hz (in MST) as it is in DP10.2 bandwidth

 

However, I do not think the DP Subsystem IP does not support 3D. In the DP spec, 3D is done on in-band stereo and this is not supported by the core:

Dear @florentw,

Thanks so much for your fast reply.

 

But you didn't ask those 2 questions:

"

Where does the 2nd stream will be presented on ? on AXI4S Video Str2 ?

 

Furthermore I would also need to know if switching from mono to stereo is dynamic.

"

Can you give me and answer ?

 

Best regards,
Andrea
