Many KDE4/Qt4 applications have poor support to high DPI screen, including Amarok, Clementine.Īll GNOME3 core applications are perfectly engineered for high DPI screen. Gwenview's image viewer is a bad example. This is caused by missing HiDPI support in source code. However, here might be some graphics, like icons and images, are blur. After configuration, tool bar icon size is big enough.Īlmost all KDE5/Qt5 applications work out of box in KDE. Set Zoom correction factor to 200% (depends on your scale factor). Open menu Edit -> Preferences, choose Interface in the dialog.Ĭhoose Larger for all icon sizes. However, you can do a little configuration to make it much better. Cursors and control box of shapes are small.Inkscape looks poor on high DPI without configuration: Here are some community made high DPI icon theme for GIMP:Īfter install this icon theme, toolbox icon in GIMP will become normal. Radio button, checkbox and scroll bar are small in KDE.Toolbar icons are scaled bitmap picture so they are not clear and sharp.Note: you must reboot system to make these settings take effects.Īlmost perfect. In System Settings -> Fonts module, check if Force font DPI was set to correct value. You can change scale factor in the opened dialog: In System Settings -> Display & Monitor module, scroll down and click the Scale display button at the bottom. If the file is empty, consider generating an example config file to ensure the correct format: Here is no option available on YaST or KDE System Settings, you need to modify /etc/nf and add the following option: SDDM cannot detect your screen DPI so it won't scale to fit. SDDM is the default desktop manager in KDE 5. After that, boot menu will always scale up to resolution of your choice. To change it, open YaST -> System -> Boot Loader, in Kernel Parameters tab, change console resolution to a specific value, NOT Autodetect by grub2. In high DPI devices, texts of boot menu are too small.
You should balance what you want: a larger space to show four windows at the same time, or a nice and beautiful desktop.īy default, GRUB automatically detects the resolution of screen. However it will make the available desktop space smaller. Increasing scale factor could make fonts and user interface bigger and sharper. If you have a 27 inch 4K display (resolution is 3840x2160), you want to display 2 pixel width for 1 actual pixel width, the scale factor is 2.
