[SOLVED] Syslinux resolution higher than monitor's

So, I'm making a persistent USB Live system to use as a repair tool and portable computer. I'm using syslinux as bootloader.

I want to set a graphic menu with a background splash. Let's say that I set the resolution to 1366x768, my laptop's native one. What happens if I try to boot that system in an old computer with a graphic card and a monitor which support up to 1024x768?

Why not just try it and find out.  I don't use syslinux on the machine I'm on, so I can't at the moment.  You wouldn't even need a different computer, just set the resolution higher than your current system can use, and see what happens.

Yeah, the problem was of really simple solution, even if I didn't think about it. Once in a while, it's nice to find the answer to a question on my own

A resolution too high behaves just like an unsupported solution, i.e. one which doesn't get outputted by

hwinfo --framebuffer

In other words, the vesa menu isn't loaded, and the basic 640x480 menu is loaded instead.

It would be nice to somehow load the highest resolution supported, but I don't think it's possible. Anyway, having a bootmenu which looks polished when I use it as booting OS on my pc and looks instead like those uber-professional recovery tools (to be effective it must look bad xD) when I use it to restore some other PC is good enough.

Topic solved, we can close here.
