Running on HiDPI screen

Running Bisq on a HiDPI screen (2k, 4k, etc) with default settings often leads to small text.

This article covers how to fix this issue on Linux.

Command-line fix

Adjust scaling with the following prefix:

JAVA_TOOL_OPTIONS="-Dglass.gtk.uiScale=1.4" /opt/bisq/bin/Bisq

/opt/bisq/bin/Bisq is the default application directory on Linux. If you run another operating system, you'll need to replace that path with the one for your OS.

You can adjust the scaling factor as you wish, of course, and add any runtime options for Bisq as well.

GUI fix

To have this setting apply automatically when running Bisq from a menu icon, you'll need to adjust the launcher files to run a script with the fix in it.

1. Create the script, say /opt/bisq/

JAVA_TOOL_OPTIONS="-Dglass.gtk.uiScale=1.4" /opt/bisq/bin/Bisq

2. Make it executable.

chmod +x /opt/bisq/

3. Update the launcher (/opt/bisq/Bisq.desktop and/or /usr/share/applications/Bisq.desktop).
