 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'').

If you ask for a 4K 3840x2160 resolution, but with a bezel that is HD 1920x1080, by default Batocera will add black borders around the bezel, like on the picture above. If you want your display to be full screen, you can either:
  
   - switch to a lower resolution (like 1920x1080)   - switch to a lower resolution (like 1920x1080)
