No image in TV after boot image

  • I have 10 year old sony tv with raspberry pi 4.

    libre elec boots and works with pc display, but with TV it shows only the colorful image and after that no signal

    i have tried with hdmi safe mode, different resolutions and so on but no luck

    is there any way that libre elec will change the resolution after boot ? i don't think my tv support full HD, only HD
