GOP set/get/list is the only interface with uefi graphics we can use from bootloader. From loader, we only can try to use resolutions listed by gop list, even if the hardware does support better. This is the firmware limit (check for update?). Once operating system is running, X11/DRM drivers can switch to use better resolution.
