Using Monitor-Relative Coordinates for Borderless Mining Window Placement

guide

Borderless Mining includes a setting that controls how the mod interprets the position you give it for your game window. That setting is Use monitor-relative coordinates, and understanding it is the key to getting the window to land exactly where you want it, especially on multi-monitor setups.

What the Setting Does

The Use monitor-relative coordinates option changes the frame of reference for window placement. When it is active, the coordinates you supply are measured from the monitor itself. When it is not active, the coordinates are treated as absolute, meaning they are measured from a fixed origin rather than from the edge of a particular display.

In short, this option lets you describe where the window should sit relative to the screen it appears on, instead of describing that position in absolute terms.

Why the Distinction Matters

On a single-monitor system the difference between the two approaches may be easy to overlook. The moment a second display enters the picture, the two modes diverge. Absolute coordinates refer to one shared coordinate space that spans your whole desktop arrangement. Monitor-relative coordinates refer only to the individual monitor. If you move the window to another display, or if your monitors are arranged in an unusual layout, the same numbers can produce very different results depending on which mode is selected.

Choosing monitor-relative placement means the numbers stay meaningful per display. You are effectively saying "this far from the edge of this monitor" rather than "this far from the origin of the entire desktop."

How to Operate It

Open the Borderless Mining Configuration screen.
Locate the Use custom dimensions option and make sure it is turned on. Custom window dimensions are what the coordinate setting applies to, so this needs to be active for your placement values to take effect.
Find Use monitor-relative coordinates and toggle it according to how you want your coordinates read. Turn it on to measure from the monitor; leave it off to use absolute positioning.
Enter your desired window position values. With the option enabled, those values are interpreted relative to the monitor.
If your game window does not appear where you expect, switch the option to the other mode and compare the result. This is the quickest way to confirm which frame of reference matches the numbers you have.

The setting is a toggle, so no confirmation step is required beyond selecting the state you want.

Borderless Fullscreen — when this is on, the mod switches to a borderless fullscreen window at the moment Fullscreen is turned on.
Fullscreen Resolution option — this adds an entry to the Fullscreen Resolution slider that enables the mod.
Borderless Windowed — the video mode name associated with the mod's borderless window behaviour.

A Note for macOS Users

The Fullscreen Resolution option is disabled by default on macOS, because that platform already handles native fullscreen well. On systems other than macOS, that particular option has no effect.

Practical Summary

If you want your window placement values to be read from the edge of the monitor rather than from an absolute desktop origin, enable Use monitor-relative coordinates inside the Borderless Mining Configuration screen, with Use custom dimensions already turned on. If the window lands somewhere unexpected, flip the toggle and test again. For most multi-monitor arrangements, monitor-relative coordinates are the more predictable choice because the numbers stay tied to the display you are targeting.
