    65This page contains information on how to optimize the JOSM interface for a high-resolution display.

    1091. Proper HiDPI-support was added with Java 9 and some improvements were made in the following versions, so make sure you are running the latest Java version.
    11 2. An [wikitr:/WikiStart up to date] JOSM version is required.
     101. An [wikitr:/WikiStart up to date] JOSM version is required.

    1312You can expect best results with even scale factors, e.g. 200%, 400%, ... but other values are supported as well.

    1515== How to enable HiDPI mode ==
    16 
    1716If HiDPI mode is not enabled out-of-the-box, here are ways to activate it.
    1817
    1918=== Windows ===
    20 
    2119On Windows, you can activate scaled display mode system-wide. See for example [http://pccleaningtools.com/how-to-enlarge-display-text-in-windows this] extensive help page.
    2220
    23 For Windows 7, the option is called ''Display / Set custom text size (DPI)'', for Windows 8 it is called ''Display / Change the size of all items'' and for Windows 10 it is ''Display / Customize your display / Change the size of text, apps, and other items''
     21For Windows 7, the option is called ''Display / Set custom text size (DPI)'', for Windows 8 it is called ''Display / Change the size of all items'' and for Windows 10 it is ''Display / Customize your display / Change the size of text, apps, and other items''.
    2422
    2523=== Linux ===
    26 
    2724You can activate HiDPI-mode for one application by running it with the `GDK_SCALE` environment variable set to 2, 4, ..., e.g.
    2825{{{#!bash
     
    3027}}}

    3230== Tweaks ==
    33 
    3431 Background imagery:: By default, the tiles of the background imagery are scaled by the same factor as other GUI elements. This ensures appropriate font size, in case the background imagery contains text and symbols. However, it leads to reduced image resolution.
    3532
    36  Under [wikitr:/Help/Preferences/Imagery Imagery preferences] / Tab ''Settings'' / ''Tiles zoom offset'', you can set an offset of 1. This makes JOSM fetch tiles of one zoom level higher and double the image resolution. Currently, this setting only applies to main map area and not the download dialog.

    3734
    38  Menu font size:: The font size for the main menu can be scaled by a certain factor using the advanced preference value `gui.scale.menu.font`. It is intended for relatively small adjustments. (JOSM r12923 or later)
     35 Menu font size:: The font size for the main menu can be scaled by a certain factor using the advanced preference value `gui.scale.menu.font`. It is intended for relatively small adjustments. (JOSM r12923 or later).
    3936
    4037 Icons sizes:: There are advanced options `iconsize.*` to tweak the default icon sizes. In particular `iconsize.smallicon` will affect the icons in front of menu items, but also on some other places, e.g. in the panels on the right.
     
    4239 HiDPISupport Style:: [wiki:/Styles/HiDPISupport This] style scales the drawing of the map area using MapCSS tools. It was created at a time of poor HiDPI support in Java and should only be required in exceptional cases.
    4340
    44  Image scaling (deprecated, experimental):: The advanced option `gui.scale` was used to scale the GUI, basically trying to implement what is now available as Java 9 HiDPI support. It only got as far as scaling images. Further development is not planned as it is obsoleted by the Java 9 features. This option may be removed in a future release of JOSM.[[Image()]]
