No HDMI Signal after launching Game

dtrunk90

Hello everyone,

I’ve flashed batocera-5.26-rpi4-20200527.img.gz onto an 128G micro sd card.
The system is booting, EmulationStation is showing up but when selecting the following games the TV screen turns black and showing “No HDMI signal” after a couple of seconds:

SNES
- Classic Kong
Ports
- MrBoom

The following games are working though:

GBA
- Space Twins (showing up a GBA device for a couple of seconds, TV screen turns black, “No HDMI signal” notification and after some seconds again the game is working)
C64 games seem to work as well (showing a blue cmd)
Ports
- Doom

I didn’t tested all pre-installed ROMs. Just the ones mentioned above.
So some games are working, some are not working.
It’s a fresh install on an RPi4.
What’s wrong?

EDIT: Just checked. The screen turns black sometimes without doing anything while staying in EmulationStation.

Hi! Can you try 1080p video setting using this post?

Try too: config_hdmi_boost=5

Tomstrug With these configs it won’t start anymore. I can see the batocera boot screen and then everything is black and stays black. ssh is not working anymore as well. Without config_hdmi_boost=5 (keep it 0) it seems to work now. I’ll give feedback after a couple of testing hours. Thx!

Yes, everything seems fine. No HDMI signal errors anymore. Thx again.
