 If you absolutely want to use the 4K resolution for whatever reason (shaders looking better, you have a non-standard wide format on your TV/monitor...), you can force the **STRETCH BEZEL** option too. Same thing, this is something you can do on a system-by-system basis. **WARNING** this has an impact on the emulation performance. If you absolutely want to use the 4K resolution for whatever reason (shaders looking better, you have a non-standard wide format on your TV/monitor...), you can force the **STRETCH BEZEL** option too.

 +==== When EmulationStation feels sluggish on a 4K TV====
  
 +There are some SBC + TV combinations where EmulationStation feels sluggish (default theme seems to be lagging behind, with a refresh rate like 10 FPS). It's really depending on your own configuration, but we have reproduced this with a Raspberry Pi4 and a couple 4K TV models. By default, ES should negotiate with your TV to fix its resolution to 1080p, but sometimes your TV brand doesn't accept it and stays at 4K/2160p resolution.
 +
 +To force 1080 in those cases, edit ''batocera.conf'' and add a line:
 +
 +  system.es.maxresolution=1920x1080
 +
 +This shouldn't be necessary for most TVs, though, and the default mode can be set back with ''es.maxresolution=0'' (or just comment out or remove the line in ''batocera.conf'').
