DisableMonitor VS Rectangle

DisableMonitor (free) - lets you apply a custom resolution to your internal or external monitors (e.g. 1920x1080) Available on GitHub

I'm wondering if the same is possible on an M1 machine—through a tool like DisableMonitor, can you force 8k resolutions on an M1? Or, if not, does selecting 4k run it truly at 4k (e.g. 1:1 rendering for blurrier visuals on the pro display), or does it render at 8k and downscale?

I use Screen Sharing to have my Macbook screen show on my iMac. Works flawless over Gigabit, except that cmd-tab sometimes lags. There are tools available[0] that allow you to set a higher resolution for a screen than what would be sensibly supported by the LCD panel. Although it doesn't do retina this way.

Rectangle’s installation is incredibly straightforward. Its immediate out-of-the-box functionality was a pleasant surprise. For anyone seeking to reduce the friction of window management on their Mac, Rectangle is a solution I wholeheartedly recommend.

Tip: I use Rectangle app to set up keyboard shortcuts to resize windows (I only have three shortcuts there: left/right half of the screen and full screen).

But Raycast also has some functionality in that direction.

Two more little utilities that I cannot live without on Mac:

A tiling window manager like https://rectangleapp.com/

Muzzle, which automatically silences desktop notifs when you're screensharing https://muzzleapp.com/

I suggest using Rectangle instead of Magnet; it has the same features but is free. I don't know what other Windows features you want to have.

I’ve used this app forever. Adds in all the window snapping features.

third-party window management apps like Magnet and Rectangle

Rectangle Mac - Move and resize windows in macOS using keyboard shortcuts or snap areas, similar to Windows.

I was a Spectacle user for years, but I recently switched to using Rectangle for window management. Rectangle has a few more options than Spectacle; I’m still getting used to it but I have no strong feelings either way.
