Overview
PCGamingWiki lists ultrawidescreen support as unknown/unconfirmed for BOOK OF HOURS, and the only fix found is a community hex-edit of UnityPlayer.dll combined with Borderless Gaming to force a custom resolution - not an official or maintained mod. No native ultrawide menu option was found, so this is rated conservatively as fix-required with unverified stability.
