I current have 3 monitors and was looking for a solution to fix the scaling between a 4K monitor and a 1080p monitor.

Most applications scale when switching monitors but Eclipse doesn't. The font is either large in 1080p or small in 4k. The zoom function sets the size for the whole application and not a single window.

Edit : I am using Eclipse Oxyen on Windows 10

    There are many known issues with using hi res displays with Eclipse. Please update your post (rather than adding a comment) to specify your operating system, and what version of Eclipse are you using. – skomisa Mar 27 '18 at 19:02

I can think of two ways to go about this.

Windows 10

Customize the scaling of each monitor.

  • Go to Windows Settings > System > Display page.
  • Select the display to customize.
  • Scroll to the Scale and layout section.
  • Choose the % of the Change the size of text, apps, and other items option.
  • Repeat for each monitor as desired.

Eclipse IDE

Customize the CSS of themes.

  • Close Eclipse.
  • Edit the desired theme: 
    $ECLIPSE_HOME/plugins/org.eclipse.ui.themes_XXX/css/**/*.css
  • Restart Eclipse.

CSS has multiple ways of specifying font size. Supposedly there is even a means to size fonts relative to screen resolution. You'll have to play with Eclipse's CSS engine to see what it supports.
