We just ran into the "MDT WinPE Booting into UEFI Resolution Issue" ourselves.
Have you tried modifying the Wizard.css file? We had the same problem booting models into UEFI that had screens supporting very high resolution. Evidently, WinPE 10 adjusts the DPI based on detection as has been mentioned. It looks like we were able to fix this by converting "font-size" "pt" values in the "Wizard.css" file to "px" values using a conversion chart such as this: http://websemantics.co.uk/resources/font_size_conversion_chart/ So, for example: ---------------------------------------------- * { font-family: Segoe UI, MS Sans Serif, Sans-Serif; color: black; font-size: 10pt; font-weight: normal; } ---------------------------------------------- Should be updated to: ---------------------------------------------- * { font-family: Segoe UI, MS Sans Serif, Sans-Serif; color: black; font-size: 13px; font-weight: normal; } ---------------------------------------------- There are only a few "font-size" values to update in the "Wizard.css" file. Some of the CSS is actually commented out at the top too. We've tested this using WinPE 10 in Legacy and UEFI and the wizard looks correct in both. It would be nice if we could get this fixed in the next MDT update. This electronic message contains information generated by the USDA solely for the intended recipients.
