I tried passing my laptop HDMI output through the Arty board, and also a SNES mini console.
The result is a mostly black screen that keeps turning off and on again. If it's on, the display is really distorted and the colors aren't correct:
I know that my device is working because with the demo that's installed in QSPI pass through is working.
I've been trying different things all day long and now I'm really out of ideas what the problem could be. The monitors that I tried it with all support 60Hz. I also tried removing the reset signal or putting it on a button. I am honestly out of ideas. Next stop for me would be to start reading the DVI to RGB sources and I'd really like to avoid that. :)
Arty Z7 HDMI Pass Through Problem

I've been trying all day to pass HDMI through my Arty Z7 20 board, with almost no success.
This is my block design:
DVI to RGBI TMDS clock range is >=120MHz (1920x1080 preferred)
RGB to DVI TMDS clock is also >=120MHz. It doesn't really matter, I tried all clock setups.
The clocking wizard is set to 125MHz input clock and 200MHz output.
These are my constraints:

Please can anybody help me?
