The display resolution of the laptop I've used to test all this up is actually 1600x900, I added other higher ones before because I expect to use this usb thumb drive on other machines for troubleshooting purposes.

As per grub docs the gfxmode setting also accepts a comma separated list of resolutions, in which case grub will try the resolutions in the list in the order that they appear, and set the first one that works successfully. Supposedly 'gfxmode': 'auto' would also work according to grub docs, in that grub would select the maximum detected resolution automatically, but it didn't work for me. So here's what I did (keep in mind this applies for ventoy 1.0.51, which is the latest at the time of this writing) - on grub/grub.cfg, around line 2079, you have this: After experimenting on grub/grub.cfg it seemed clear that trying to fix or workaround whatever is going on in GUI mode was not going to work - it looks like whatever on ventoy that resets the resolution before booting the iso is bypassed in CLI mode. I did try to just leave display mode on 'GUI', just set the resolution to the maximum resolution and booting, but it seems while the display mode is set to GUI and when you choose an ISO, ventoy will switch to (low-resolution) console mode right before booting the ISO, which ends up still constraining Strelec to a low-resolution.Īnyway, I needed a more permanent workaround, so I went digging on the EFI partition of ventoy.

But after dismissing this prompt everything will still be working normally, and at this point you can go back and select Win10 Strelec iso, and it (hopefully - again, it did for me) will boot in full resolution.
