HI,
FYI... since you already had hardware board then you can straight ahead to try out the Quartus design on hardware testing instead of relying on simulation.
Earlier you mentioned HDMI Rx is working while failure only happened on HDMI Tx.
- Then the question will be whether the failure occurs in Rx to Tx transmission path or on the HDMI Tx IP itself
- I saw you mentioned you modified HDMI IP a lot. Perhaps you can stick with original IP design first to see whether it works before you work on your modification. Just worry the design modification accidentally break the HDMI IP functionality.
- Also, I found below HDMI Tx only design. You can try it out and cross check with your design also.

Ideally the recommendation is to stay with Intel FPGA HDMI example design "untouched with exception on pin mapping changes", get it working first before you start modify the design.
Thanks.
