We're not hi-dpi aware yet, so this is how Resolume will look on a high-res monitor. Interestingly enough, a lot of people are actually loving this, because it gives them enough screen real estate to show all their layers.
The scaling will probably need to become a user preference at some point. It's going to be a while though. It's currently on the roadmap for Res 6.
Until then, apparently you can fix hi-dpi awareness by hacking manifest files: http://www.danantonielli.com/adobe-app- ... plays-fix/
. To be clear, we haven't tried this on Resolume.
