# Guides for your displays and windows

Practical answers to common Mac display, window and Universal Control problems, with macOS's own fixes first.

## Fix a problem

- [Monitor arrangement keeps changing](https://universaldisplaymagnet.app/guides/mac-monitor-arrangement-keeps-changing): Why macOS moves your displays around after sleep or a reconnect, what to check first, and how to keep the arrangement.
- [Windows move after sleep](https://universaldisplaymagnet.app/guides/mac-windows-move-after-sleep): Why your windows end up on the wrong screen after sleep or a reconnect, the free checks to try, and how to put them back.
- [Universal Control not working](https://universaldisplaymagnet.app/guides/universal-control-not-working): A step-by-step check for Universal Control that won't link, keeps disconnecting or sends the pointer across at the wrong edge.

## Set things up

- [Universal Control between Macs](https://universaldisplaymagnet.app/guides/universal-control-two-macs): Set up one keyboard and pointer across your Macs, and line up their displays so the pointer crosses where you expect.
- [Split screen on Mac](https://universaldisplaymagnet.app/guides/mac-split-screen): Put two windows side by side with Split View or macOS window tiling, and know when thirds or an app are worth it.

## Choose a window manager

- [Scrolling vs tiling window managers](https://universaldisplaymagnet.app/guides/scrolling-vs-tiling-window-managers): Snapping, fixed tiling and scrolling compared with the same four windows, and the Mac tools for each.

## Compare with other apps

- [Universal Display Magnet vs Magnet](https://universaldisplaymagnet.app/compare/magnet): Two unrelated Mac apps with the same snapping shortcuts: when Magnet is enough, and when you also need tools for displays and workspaces.
- [Universal Display Magnet vs Rectangle](https://universaldisplaymagnet.app/compare/rectangle): Free Rectangle, paid Rectangle Pro and Universal Display Magnet: which one fits snapping, app layouts, display arrangement or several Macs.
- [Universal Display Magnet vs Moom](https://universaldisplaymagnet.app/compare/moom): Both save window layouts. Moom is built around custom window actions; Universal Display Magnet around your displays and all your Macs.
- [Universal Display Magnet vs ChainYourMac](https://universaldisplaymagnet.app/compare/chainyourmac): A dedicated scrolling window manager, or one app for your displays, workspaces, Universal Control and a scrolling strip: who should choose which.
