Resolume Forum

MacBook Pro M1
Mac OS 13.2.1
Resolume 7.14.4 & 7.15.0

When I mirror my internal screen to an external display I experience two similar display bugs: Both the preview windows and the advanced output window show an image only in the bottom left quadrant. In the preview window the content gets scaled to this area, in the advanced output window content is hidden when moved outside of the quadrant.

The only workaround to avoid this behaviour is to make the external display the main output and have the internal display mimick the other displays' resolution & refresh rate. However, this helps only sometimes.

Just do a Resolume window resize.

The issue is, that when you're enabling the Display mirror after starting Resolume, your built in display goes form HiDPI mode to no HiDPI, and that needs a UI refresh to populate.

If you're mirroring displays, you won't be able to send output to your external display.

Unfortunately, a window resize doesn't fix the problem in this case. I had it help before, but not here. The error also occurs when mirroring is activated before starting Resolume.

Same issue here with MBPro M1 13 inch, same os, resolume 7.15.0
