The hatches of Skalp are not vector based, so Hybrid is necessary. But the hatches are made fine enough for profesional output.
The settings for screen and output do not match, nor can be compared. eg. Output ‘High’ is 300dpi, while Screen set to high will be depending on the used screen (probably 96 ppi - 170)
Good support for higher ppi monitors is something is worked on, hopefully, so you can ‘see what you get’
