HDMI no signal when booting game

[mixalakis989]

Happy new year
I have a Recalbox 7 on Raspberry Pi 3b with a 256gb san disk. the system boots fine but when i run any game it shows me no signal. i tried 2-3 4k tvs and changed hdmi cables it works fine.

let me know if this is fixable

Thanks
Michael

It is a known problem between 4k TVs and RPi4, it will be fixed in the next version:

• Fix detection of 4k screen (#1384) (https://gitlab.com/recalbox/recalbox/blob/master/CHANGELOG.md)
