Hi. I've been using Recalbox on a Raspberry Pi 5 connected to a FullHD LG TV for months without any problems. But when I tried to connect it to a (quite old) Sony LCD with a 1366x768 resolution panel, It had no picture while booting and in EmulationStation. The weird thing is that I had it configured to automatically start Kodi after booting, and then it just showed Kodi at 720p. I tried to leave Kodi, no picture again. I tried to use HDMI safe mode, no luck there. I also tried to force 1366x768, 720p and 1080i resolutions, no luck there either.

This TV has only one HDMI input, and it seems it doesn't support 1366x768 resolution in any input other than the VGA one, but in theory it supports 1080i. Does anyone has any suggestion on how to solve this issue?
