Hello everyone! I have tried my best to investigate and be able to solve this problem, but have been unable. I have a Raspberry Pi 4 B (4gb ram) with Batocera 5.25, the problem is that my TV is 4K and the games are not working "fluently". I am sure that if I can change the resolution to 1080 (full HD) or 720p everything would be better. I don't know how to exit the interface to access the Linux configuration, or how to modify the resolution.
I thank you in advance for any help!
