Stream output in 1080p, record in 4K?

[sensible]

I'm using a 4K canvas, can I record my stream in 4K but have the stream output set as 1080p?

I have the computer power to do it, but not the internet connection to upload 4K stream. Plan to use the 4K footage from the recording in videos later though.

Yes, the Output tab has a Recording tab, and a Streaming tab. You can set them up independently. And as you noted, that means plenty of extra computation to do 2X rendering. Have you tested 4K recording to make sure you have Disk I/O, etc to sustain 4K?
