Orange Pi 5 Ultra HDMI RX no video when connecting Walksnail VTX Ascent

Orange Pi 5 Ultra HDMI RX no video when connecting Walksnail VTX Ascent.
When I connect Walksnail Ascent VRX, the picture is fine, but when I connect VTX Ascent to VRX, the system doesn't see the HDMI RX. Specifically, it sees the source but can't lock it.
The settings are set to 1080p60.
I've tried different kernel and OS builds, but the result remains the same. What are the ways to solve this problem at the software level, since I specifically chose the Orange Pi 5 Ultra because of its built-in HDMI IN.
