Hi everyone,
I have a big problem with my raspberry pi4, i buy a nespi case 4 and a raspberry pi 4b with 4go ram with the 3 A supply. I use batocera 5.27.
I put the hdmi on my computer screen and i don’t have signal, i try on my tv and it work first time, then i try on my gf tv and nothing. I try so many option in the config file like, force hdmi, boost signal but nohting work.
Does anyone can help me solve my probleme?
If you need more information tell me.
thank you.

Hi, Thank you for reply, actualy no i havn’t tested this one, i’m on it right now.
Just a quick question about the boot.tar, what is this? do i have to use it somehow? Or just batocera?

No, it didn’t work, i try to modifie again the config file too. But i think the TV is too old… Q. Media ql3252c from 2011, maybe less (amazon sell it for the first time in 2011) i also check my HDMI câble it say HDMI 1.3.
Wednesday my gf and i go buy à new bigger one i think 😁😁
