Occasional ContributorHDMI Intel FPGA IP as Receive with AXIS fails in Analysis & Synthesis of Quartus 24.3 Pro
Hi @M_DK_FPGA ,
I understand your reason to turn off the "support Aux" and "deep colour" with reason to support your custom 24 bit pixel data.
However , turning OFF support Aux and deep colour will make the output in-stable (blank most of the time).
Also, This will only save minor logic utilization. That why we make those two as default to suit most of the use cases.Currently AXI Bridge is setting to 16BPS (16x3 48bits).
If fewer bits are requires, you just need to pad the LSB without disable the AUX and Deep Colour.
Detail about the implementation you may refer to- HDMI user guide 5.1.19. AXI4-Stream to Clocked Video Converter (AXI2CV)
- Intel AXI Streaming Video Protocol Specification: 2.2.10. Packing RGB444 onto an RGB888 Interface
Hope that able to help you to move a step forward, let me know if further clarification is needed.

Occasional ContributorHi Your Intel Community Team,
After my above reply with question, I got a mail asking "Did it solve your problem?".
Based on this, I would like to point out that, that the problem is still open based on the contradictions in the documentation and tool, as I pointed out in the reply, where I also have an open question.
Any attention to this problem is greatly appreciated.
Regards,
