UEFI PXE OSD Background Picture size

[act_cpsb]

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

if you add a restart computer step, does it improve ?

A restart in general or after the video fix?

The computer restarts several times during OSD naturally and it does not improve in those instances. Ill try a reboot after the video fix.
