Troubleshooting • Raspberry pi 3b plus rev 1.3 bookworm no HDMI output

Hello, I purchased this board yesterday and everything is working so far besides ofc HDMI output on 3 TVs and 1 monitor.

I am a total Raspberry noob I managed to flash Bookworm 64 and 32 and some legacy versions from Rasberry Pi Imiger.
After a whole day of reading and trying i understand that on Bookworm "hdmi_" commands are not going to work also I need to use "dtoverlay=vc4-kms-v3d" (whatever it is :X)

I discovered via SSH commands that my Raspberry is detecting my TV connected to the HDMI port it can even detect the manufacturer and it shows what resolution it was trying to use but i may be mistaken here maybe it was something else.

Now I am on Bookworm clean flash of 64bit version if anyone has any ideas on what else I can try to fix HDMI before i just assume that something is just broken on this board.

(The tv that pi is connected to now LG 42LW4500 it is fhd but i have no idea about the refresh rate.)
