It seems that due to hdmi_safe=1 in config.txt (see #3115), only one HDMI port works, the other shows the rainbow. It should be easy to fix by settings that option for both ports. See https://www.raspberrypi.org/documentation/configuration/config-txt/video.md and https://www.raspberrypi.org/documentation/configuration/config-txt/conditional.md

Linked PR did not fix the issue. https://www.raspberrypi.org/forums/viewtopic.php?f=91&t=243899 and some other threads show that it might be easier to return a splash screen and mention the problem in Talos documentation.
