Hello,

We are going to need to review their schematic.
Can they take a scope capture of the clock signal at 1080i and 1080p?
Does is happens with other video sinks?
Does the video sink support 1080i?

Regards

Hello,
Sorry for the delay.
I reviewed the schematic and it looks correct.

Are the 5 video sink the same monitor model?
Have you tried different video sources?
The DP139 does not care if it is 1080p or 1080i, so this has to be some mismatch between source and sink.

Just for background, I see on the video that you selected 1080i@60 fps so basically you are actually watching a image @30fps, can you select 1080i@120fps ?

Can you try your video source and video sink without using the dongle?
