Nexys video HDMI in EDID

[Ruskuls]

I'm designing custom FW  for Nexys Video development bord.

In my design I'm using two Nexys video development boards, each board has identical FW.

For both Nexys Video development boards video stream are fed from DisplayPort output. To convert DP to HDMI I'm using CSV-6200H Multi Stream Transport Hub DisplayPort 1.2 Dual Monitor to HDMI

When this set-up is connected to the computer it can regonise Nexus devices, but computer become unresponsive.

If Nexys HDMI in is connected directly to the same PC, it works like a charm.

Weirdest part that with higher resolution (854x2880@60Hz) PC is working, but if resolution is reduced to 854x1920@60Hz it stalls /stutters.

 

won't work with Computer GPU Titan pascal / RTX 2070

Works with different input resolution Nvidia Quadro K620 / P600

My assumption - issue is CSV-6200H, but I would like to hear Your opinion.

Could You suggest converter from DP to HDMI, to be compatible with Nexys Video board?

P.S. Currently I'm waiting for different DP1.2 to HDMI

Hello @Ruskuls,

I also think that the CSV-6200 converter is the reason you are having problems. We recommend that the users should use a direct connection with the PC through a HDMI cable, without a converter.

We currently don't know what converter could be compatible.

Your PC stalls when you reduce the resolution if you are using the converter or if you are using only the HDMI cable?

Cheers,

Hi @Ana-Maria Balas

Yes, PC stalls when converter is used.

Problem were solved with DP 1.4 cable.

Thanks,
