Yes, you can scale the UI up in both UVI Workstation and Falcon. It's very nice on a 4k screen. Definitely a win there. I didn't have any trouble rolling back to the old version when this problem showed up, so I'd think it would be safe to at least try the new version, since you can uninstall and install whatever version you need. For Falcon there are a bunch of actual new features, so even more of a win.
