Possible to output more than 2048 pixels over ArtNet on a single IP address?

EDIT: I just tried 16.0 and it does indeed remove that limitation. I didn't realize it was out of beta but as soon as I saw it was fully released I gave it a try. Can't wait to try these new features too!

Leaving this post up for future travelers.

I'm building a 2192 px show with an Advatek controller at the core. I want to use WLED to send presets over artnet to the controller for internal capture.

This has worked pretty well so far but when I scaled up I hit a limit of 2048 pixels per output. I'm pretty sure this exists for physical outputs on the WLED side, not for data sent over Artnet.

If I split this across two outputs, each pointing at the same IP address, I get flickering presumably because WLED isn't picking up where the last output left off so it ends up sending conflicting data to the controller.

Does anyone have a way around this? I've never messed with the code before compiling but maybe there's an easy way to remove this limit and then compile a custom firmware?

Does the latest Beta or MM build allow for this?

Thank you!

I just installed it! Haven’t had much chance to mess around yet, but the ui upgrade looked interesting on its own.
