Hello.
Just started using rEFInd and faced the problem of resolution. It's either 1024x768 or 1240x720. I tryed changing screen resolution in refind.conf but I get error message that it doesn't support 2540x1440. Is there any way to adjust the resolution?

rEFInd relies on the EFI to set the screen resolution, and the EFI in turn relies on whatever video drivers it can find (typically in the motherboard or video card). These resolutions are limited in number, and aren't guaranteed to match your monitor's optimal resolution (although that's usually one of the ones that's available); you can't just set an arbitrary resolution. If you're using a UEFI-based PC, the failure message when you try to use an unsupported video mode should show a list of supported video modes. You must use one of them (or don't set the resolution at all).
