Since I have been doing "Try Zorin" with Z16 Lite USB, my BIOS screen on startup and also Grub Menu have changed from full screen to smaller centred window.
I have done several reboots into both Zorin 15.3 Core on HD and Windows on same HD via Grub.
In the past, a reboot would fix it, but not this time.
PS: Once Zorin 15.3 or Windows boots, screen resolution is correct.
Whilst both BIOS and Grub screens work OK they are just not full 1280x800 resolution.
Any ideas how this has happened and also how to fix?
PS: Once booted into Zorin 15.3 (or Windows), the screen resolution is correct.
