For a game released in 1998, The Settlers III handles widescreen surprisingly well, though achieving it depends on which version you own. While the original game natively supports only three 4:3 resolutions (640x480, 800x600, and 1024x768), modern re-releases and community tools have unlocked full widescreen and even 4K support. settlers.jakelee.co.uk Widescreen Support by Version History Edition (Ubisoft Store / Ubisoft+):
This version is the most "plug-and-play" for modern displays. It features native widescreen and multi-monitor support, automatically detecting your desktop resolution. It also includes support for 4K Ultra HD and Windows 10/11 compatibility. Ultimate Collection
The base GOG version still primarily uses the original resolutions. To get widescreen, you must use community patches like Settlers United , which enable resolutions up to 2560 x 1440 and beyond. PCGamingWiki Community & Professional Fixes

For owners of the original game or the "Classic" release on GOG, the community has developed a solution centered around DxWrapper (a replacement for DirectDraw) and custom launchers.
We must address whether widescreen gives you an "unfair advantage." In The Settlers III, the fog of war is based on unit line of sight, not the screen edge.
For a more tailored widescreen experience, you can use third-party patches. These patches are designed to modify the game's behavior, allowing it to run smoothly in widescreen resolutions. For a game released in 1998, The Settlers
The Settlers III’s engine was not designed to be flexible. The game’s resolution is dictated by a simple configuration file, but forcing a modern resolution like 1920x1080 through conventional means usually results in a crash or a visual mess. The core challenges are:
Released in 1998 by Blue Byte Software, The Settlers III (Die Siedler III) marked a pivotal shift for the beloved city-building and RTS hybrid series. Moving from the DOS-era 2D sprite work of its predecessors to a full 3D isometric engine, it offered a vibrant, cartoonish medieval world. However, like most games of the late 90s, it was built for a 4:3 CRT monitor. Resolutions like 800x600 or 1024x768 were the peak of its ambition.
For modern players with ultrawide or standard 16:9/16:10 monitors, booting up Settlers 3 today presents a problem: black bars, a stretched UI, or a tiny, postage-stamp-sized game window. Fortunately, the dedicated community has ensured that the Roman, Egyptian, and Asian legions can march across modern displays in full, glorious widescreen. 16:9 (1920x1080): Perfectly playable
To understand why widescreen is such a sensitive topic for Settlers III, one must first understand its engine architecture. Unlike early 3D games where the camera is a free-moving object in space, Settlers III uses a fixed orthographic (isometric) 3D engine.
In 1998, developers Volker Wertich and his team made a critical decision: the game world is a finite grid. The UI—the status bars, the command menus, the minimap—was hard-painted into the same frame buffer as the game world.
When you run a standard hex editor on the S3.EXE file, you will find that the game’s internal logic relies on a specific "safe zone" of 1024x768. If you force a modern resolution like 1920x1080 via a simple registry hack, a horrifying thing happens: The game renders the world perfectly, but the UI remains glued to the center of the screen. Suddenly, your wood supply icon is floating in the middle of your wheat field, and the "Build" menu obscures your barracks.
This is the "UI Lock" problem. It is the primary reason why for nearly fifteen years, the community insisted that The Settlers III could never truly support widescreen.
