It is strange that 1024x768 is not supported. That is the standard resolution for most UEFI BIOSes that I know of.
Are you sure you have set the resolution in the UEFI menu page of ventoy.json and not just in the first page in VentoyPlugson?
If you press 'c' in Ventoy menu and then type videoinfo you can see what modes are supported.
e.g.
set pager=1
videoinfo
Of course QEMU will give different results from a real system.
