The ability to choose 1 or 2 bit rendering on a per-plugin basis is not yet a released feature. It will be released in late 2025.

Seeing 2-Bit Images with a Demo

When 2-bit was released with firmware version 1.6.x or higher, we enabled it automatically with the Redirect and Alias plugins, since they were primarily used for images, it was a great way to show-off the functionality if you properly formatted the images you were targeting.

Thanks to a community contribution, a few easy steps lets anyone see the glory of the 2-bit upgrade for images.

  • Set the Web Address to: https://2bitdemo.scottlabs.io

  • Click Save

That's it! Now a random 2bit image will be displayed on the frequency you set in your playlist.

Enable 2-bit for your Device

This feature is available to any account with firmware version 1.6.x or higher (1.5.12 is 1-bit only).

You can now set the palette at the device and playlist item levels.
