With this UI you can have a full header image (498x57) without having to use MUI_HEADERIMAGE_BITMAP_NOSTRETCH. That way the header will be properly resized on systems with different dpi.

Presuming you've placed it among other UIs, use:
!define MUI_UI_HEADERIMAGE "${NSISDIR}\Contrib\UIs\modern_headerbmp_full.exe"
