Resolume Forum

Hi. I have some problem with aspect ratio when using Resolume on Macbook Pro M1. When external monitor is connected, MBP display proper aspect ratio, but when I use Resolume, aspect ratio is different (for example circle is more oval). This issue sometimes happen, sometimes not. I can fix it by changing scale W to 110%, however could be nice to know why is happening. I've tried several monitors and projectors with the same result.

Different on the output or the Resolume monitors?
Do you conenct the external display after starting Resolume or before?

On external monitor/projector. Mostly projectors. I connect projector before launch Resolume.
MacBook Pro M1 2020, OS 14.2.1, Resolume Avenue 7.13.2.
