@XSOM I don't think that Pro X6 will get a 4K GUI. This would be a major new feature and will likely only appear in a new version.
I hope it appears in the X7 version. There are many devices on the market with this resolution. Users who want to work in Samplitude must purchase an FHD monitor, because Samplitude still doesn't have support for 4K. Magix should respond to the market. Today it is standard and Samplitude is behind.
