I just set up a 4K display, and googling has found me basic fixins: https://urldefense.proofpoint.com/v2/url?u=https-3A__www.makeuseof.com_tag_linux-2Dhidpi-2Dsupport-2Dfor-2Dgnome-2Dkde-2Dxfce-2Dcinnamon-2Dand-2Dfirefox_&d=DwICaQ&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=PRl7GrNK8n6DuVgh4ktAsasUIdCgBggpIOupwJTZ6IU&s=PZhZGO9zyfMYDIcEVM7L1f9YBEIhWUkn6eSEk6wLly8&e= I also found the Default-hdpi theme.
