PS4 works only in 1080p or lower

PS4 Questions PS4 Pro

Hi,
I have a ps4 pro where i replaced the hdmi ic and Port. When i connect it to a 1080p Monitor or TV it works without Problems. On my 4K TVs it try to Display 2160p (RGB) and i do not get any output on the screen. I can force the ps4 to Display 1080p on my 4k TV via safemode but when i try to Set it to 4k i get no output. When i disable deep color and hdr i get IT to Display 2160 yuv
but there is a barely noticeable static noise in the picture. Does anyone know this Problem?
Can this Problem occur from a Bad Solder Job?
I tested it with different hdmi cables. The Original Ps4 and PS5 One and an 3rd Party Cable. The PS5 Cable works slighty better but still gets the noise.

Best regards

Sounds like HDMI IC issue

Final Updste:
It was a Bad solder joint on the HDMI IC.
After some more try i managed to solder it probably.
Now the ps4 works in 4K HDR.
