Perhaps my googlefu is just failing me but I cant seem to find a definitive answer for this.
Background
Windows 10 x64 OSD to different Dell models, laptops and desktops via SCCM 2012_1602.
Custom OSD background image in the x32 boot.wim and it has been working well with BIOS PXE booting.
The image is 1024*768. Screen sizes vary in resolution.
Dell is requiring us to move to UEFI booting on new models.
Changes Made
Swapped over to an x64 boot.wim since UEFI seems to require that.
Adapted the TS to detect BIOS/UEFI and format disk appropriately.
OSD seems to work find in all other aspects.
Issue
OSD background image shows properly when BIOS PXE booting.
OSD background image seems to be zoomed in or not scaled correctly when UEFI PXE booting.
Have tried using an MDT boot.wim and one made from the OS source disk, same result.
The image is 1024*768. Screen sizes vary in resolution.
Looking for Solutions
Ive found Niall Brady's solution for correcting a video resolution issue on a Lenovo Thinkpad 10. I dont think it is the same issue, the resolution of the screen seems fine, just the background image is not scaled properly. I did try his fix and it did not work to fix the background image scaling issue.
Does anyone have thoughts/information on this?
Or is there a fix in a future version of SCCM? We will be moving to newer version at some point, just not sure when.
Thanks
